Link for citation: Mrakin A.N., Afanaseva O.V., Kuleshov O.Yu. Calculation of heat transfer intensity of gas fuel combustion products. Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 5, рр.109-115. The relevance of the research is determined by the modern trend in the field of thermal power engineering and heat engineering for the transition from traditional gaseous fuel (methane) to the use of hydrogen, methane-hydrogen mixtures, as well as thermochemical conversion gases. Switching to new non-design fuel is justified by considerations of reducing the negative impact on the environment and increasing the thermal efficiency of fuel combustion plants. In this case, the use of fuels with a composition different from the design one will affect the heat transfer processes. The main aim: carrying out a comparative analysis of indicators of the intensity of radiant and convective heat transfer of combustion products of non-design fuels, such as hydrogen, methane-hydrogen mixture and thermochemical conversion gases. As an assumption in the formulation of the problem and objectives of the study, the constancy of the heat release power in the apparatus due to changes in the amount of fuel burned was taken. Objects: heat exchange surface of a fire-tube hot water boiler. Methods: carrying out numerical calculation using traditional approaches to determine the indicators of the intensity of heat transfer in the system «combustion products – metal wall of the pipe of thermal power plants». We also used the relations tested earlier by other authors to calculate the thermophysical parameters of gas mixtures. Results. According to the results of the performed comparative calculations, we can conclude that the transition from the use of conventional fuel (natural gas/methane) to its thermochemical conversion gases under the considered conditions has almost no effect on the integral heat transfer performance. To a greater extent, this transition is caused by changes in the intensity of heat transfer for products of combustion of hydrogen and methane-hydrogen mixture, which will affect the operation of thermal power and heat technological installations. At the same time, it is necessary to conduct additional research on the combustion kinetics of thermochemical methane conversion gases, their thermophysical properties, etc., because the hardware design, type of the catalyst used and operating parameters of the process will affect the composition of obtained synthesis gas.

Water consumption behaviour and the use of technology among households in Durban, South Africa

Abstract Freshwater resources remain under constant pressure due to population growth, economic development, and changing weather patterns. Water supply utilities generally struggle to keep up with the growing demand for freshwater resources and consequently adopt demand management policies to address supply challenges. As water consumers, households can play a major role in water conservation. This paper examines the impact of biographic characteristics on water consumption behaviour and the adoption of water-efficient technologies in the city of Durban, South Africa. Probit regression models are estimated using survey data collected from 300 household heads sampled across the city. Among other results, the study finds income as the most consistent determinant of water consumption behaviours and the adoption of water-efficient technologies. Furthermore, the level of education was also found to be a consistent determinant of the adoption and installation of water-efficient technologies. These results are significant and serve to guide water utilities when implementing demand management water policies.

СОВЕРШЕНСТВОВАНИЕ СИСТЕМЫ ТЕПЛОИЗОЛЯЦИИ СТЕН МНОГОКВАРТИРНЫХ ДОМОВ ВТОРИЧНОГО ЖИЛИЩНОГО ФОНДА Г. САРАТОВА

The technical condition of many apartment buildings of the secondary housing stock in Saratov, built from 1977 to 1999, does not meet the current regulatory requirements in the field of creating optimal indoor climate parameters. The system of external thermal insulation of the "wet" type with a rigid fastening of the insulation is very common for the insulation of the external walls of these houses. It has been established that due to the fact that the masonry joints and its irregularities are not filled with mortar, the underestimated thickness of the insulation, a thin layer of the protective layer of plaster, as well as violations of the installation technology of the thermal insulation system, gaps are formed between the insulation plates and the walls, there is an access of cold air to the masonry of the walls, which leads to the appearance of condensate, freezing of walls, an increase in humidity and a decrease in the temperature of the indoor air in apartments. The penetration of cold air through the walls leads to increased heat loss, cooling of the masonry mass and a shift in the "dew point". As a result of the instrumental examination of houses, it is found that the freezing of moistened insulated walls led to an increase in their heat loss by 10-20%. An alternative system of point thermal insulation has been studied, in which the insulation boards are attached to the wall using hinged fasteners, excluding deformation and destruction of the protective plaster layer 10–20 mm thick and the insulation. The optimal thickness of the insulation brand PSB-S 25 for the climatic conditions of the city of Saratov is determined. The technology of mounting a movable thermal insulation system is improved using a deep penetration primer and glue for applying insulation to the plates, which makes it possible to reduce the mass of the structure and reduce the cost of installation work. The effectiveness of the use of a movable thermal insulation system to improve the energy efficiency of multi-apartment buildings of the secondary housing stock in the climatic conditions of Saratov is shown

Numerical Simulation of an ICP Plasma Torch and an HF Generator Taking into Account Their Mutual Influence

In developing electrotechnical plasma equipment, one of the most important issues is the coupling of a power source and a nonlinear load (in this case, a ICP plasma torch). The following factors affect the power supply operation: the method of gas supply to the plasma torch, operation mode, gas consumption and composition. The power supply can influence the plasma flow pattern in the plasma torch through the volt-ampere characteristics. The article addresses matters concerned with studying the processes in the ICP plasma torch electrical technology installation and revealing regularities influencing the plasma flow generation. An ICP plasma torch and its power supply are numerically simulated with taking their mutual influence into account. A 2D axisymmetric model of the operation of a plasma torch that uses argon as a plasma-forming gas is considered. The gas flow is described by the turbulent k-ε model. A power supply equivalent circuit is proposed for its implementation in the Comsol Multiphysics software package. The possibility of coupling a power source and a plasma torch in one model is shown. The distributions of velocity, temperature, and electrical parameters over time are obtained. By using the proposed approach, it is possible to analyze the sensitivity of the electrotechnological processes in the ICP plasma torch to the power source electrical parameters. This article is the first one in a series of studies on simulating the "power supply-plasma torch" system.

Numerical investigation of the aerodynamic and wake characteristics of a floating twin-rotor wind turbine under surge motion

To elevate the power capacity of floating wind turbines and cut costs, development towards large-scale systems is underway. However, this requires solving the problem of fatigue loading on large, flexible blades, as well as corresponding improvements to production and installation technology. As an alternative to larger turbines, twin-rotor floating wind turbines have been proposed. The aerodynamic and wake interference characteristics of this twin-rotor are not yet well understood. In this study, we have investigated the power and wake characteristics of a twin-rotor floating wind turbine based on unsteady Reynolds-averaged Navier-Stokes turbulence model for a comprehensive analysis. Specifically, the power and wake recovery of a twin-rotor floating horizontal-axis wind turbine (FHAWT) under surge motion are compared in detail with those of a single floating wind turbine and bottom-fixed case, while both the effects of the three wind directions (β = 0°, 45°, 90°) and spacing ratios (S/D = 1.2, 1.375, 1.5) are considered. The results suggest that the mean power of the twin-rotor is enhanced by a maximum of 13% under surge motion compared to the single rotor, the small spacing ratio promotes the power gain. Surge motion plays a significant role in wake interaction between the twin-rotor and facilitates wake recovery. As compared to the baseline case, both power and wake recovery performance of the twin-rotor are boosted at β = 45°, with an increase in power of 12.7% as opposed to the single rotor. The modified Jensen wake model is proposed for the far-wake region and a modified Gaussian wake model is also suggested for different cases. This study can provide affiliated guidance for the application of the twin-rotor floating wind turbine.

Research on Installation Technology of Super Large Radial Gate of Dam in Complex Environment

Taking the installation construction of super large radial gates of Nam theun1 hydropower station in Laos as an example, due to the lag of civil construction period and the dam structure, it is not convenient for large lifting equipment to enter the installation face directly. This paper introduces the application of "Bailey beam + Gantry crane" lifting radial gate technology under the conditions of large construction interference, heavy construction task and tight construction period, The installation of super large multi hole radial gate was successfully and quickly realized, which ensured the water storage and power generation schedule of the power station. According to the normal construction sequence, the radial gate of the spillway should be installed normally with large lifting equipment in the open hole state after the civil construction junction, and the upper concrete construction should be carried out after the radial gate is installed. During the construction of the dam and the arc gate, the civil engineering is in the process of sluice construction, the concrete of the dam body is rising, the multi-process and multi-professional construction is intensive, and there are multi-directional intersecting operations, which causes great construction interference. Combined with relevant cases, this paper focuses on the installation technology of super large radial gate in the high temperature and Rainy Zone and the complex environment with limited construction site conditions, so as to provide reference for the implementation of similar projects and actively explore new advanced technology for the industry.

RETRACTED: Study on the design of composite beams under complex environment in mountainous areas

The mountain area is faced with complex conditions such as vertical and horizontal valleys, complex geological topography, many earthquake fault zones, high seismic intensity, fragile ecology, and changeable climate. The traditional concrete bridges have a heavy weight, high consumption of sand and gravel materials, large structural dimensions of steel box composite bridges, high steel consumption, and poor overall horizontal performance of steel plate composite beams, which are not suitable for mountain construction conditions. Therefore, based on the construction environment and application requirements of highway bridges in mountainous areas, the structural scheme of steel box-steel plate composite beam is put forward in this paper, and the design of a 25 m–50 m standard-span steel box-steel plate composite beam is studied. The results show that the steel box-steel plate composite beam structure scheme is adopted, which has excellent mechanical characteristics of steel box girder and simple structure of steel plate girder. It has the mechanical characteristics of “balanced transverse force and excellent longitudinal force”, so it is a reasonable choice for small radius curved beam bridge in a mountainous area, so it is a reasonable choice for small radius curved beam bridge in a mountainous area. The steel box-steel plate composite beam adopts the integrated technology of manufacture, transportation and installation, which can better meet the road transport conditions in the mountain area. The longitudinal assembly of the manufacturing unit as the installation unit can ensure the rapid and high-precision installation of the construction site, and the assembly construction of the bridge in the mountain area has been realized. The technical and economic comparison shows that the mechanical performance of steel box-steel plate composite beam is similar to that of steel box beam and obviously better than that of steel plate girder. The steel consumption and construction period of steel box-steel plate composite beam are similar to that of steel plate girder, and are significantly less than that of the steel box girder. Therefore, the steel box-steel plate composite beam is a good choice for mountain bridge construction.

The Energy Prices Act 2022: A barrier to net zero?

This legislative note evaluates the recently introduced Energy Prices Act 2022, particularly with respect to the impact that it might have on the renewables industry and the UK's ability to meet its climate change targets through the installation of renewable energy technology. The Act comes at a time where the UK and many other countries are gripped by both a global energy crisis and a cost of living crisis which has resulted in significant struggles, with some households in the UK being forced to choose whether to heat and power their homes or pay for food. The Energy Prices Act 2022 was introduced to reduce the financial burden of energy bills, and also to limit the profits made by low carbon generators. Since the enactment of the Act, further developments have been made in both of these fields. This legislative note will evaluate the contents of the Act itself, along with the further developments which have taken place and will analyse the potential impact that these changes could have on the renewables industry.

Rain Water Harvesting Technology: Drinking water fulfillment and water conservation nearby landfill area

The drawback of groundwater quality occurs due to minimum treatment of waste management in the landfill. The research objectives are to know the groundwater quality around the landfill study site, rainwater potential for drinking water purposes, and decreasing runoff due to rainwater harvesting technology implementation. The well water samples were collected from eight wells surrounding the landfill. Rainwater samples were collected from rainwater harvesting technology installation. Water quality parameters consist of total coliform, pH, and Total Dissolved Solids (TDS). Water conservation was observed by infiltration and precipitation. Total coliforms of well water are higher than rainwater. Furthermore, based on acidity and TDS values, well water is higher (pH 6.5-8.5 and TDS 188.8 + 128.7 ppm, respectively) than rainwater (pH 6.1 + 0.2 and TDS 8.4 + 1.4 ppm, respectively). Based on three parameters, rainwater is more proper for drinking water than well water in the study site. Rainwater harvesting technology is able to reduce runoff by 58.42% with the rainwater catchment area around 7,095 m2. Waste management in landfills should concern with groundwater pollution. Rainwater harvesting technology is a potential solution for drinking water supply in water crisis areas.

IMPROVEMENT OF THE PROCEDURE OF PROFESSIONAL SELECTION OF PERSONNEL FOR WORK AT HAZARDOUS PRODUCTION FACILITIES OF THE OIL REFINING INDUSTRY

The analysis of the state of accidents and injuries during the operation of hazardous production facilities of the Republic of Belarus has been carried out. It has been determined that a significant proportion of the reasons associated with the "human" factor necessitates the formation of behavioral attitudes of employees to comply with industrial safety requirements and the introduction of effective procedures for professional selection and behavioral audit of personnel to work at hazardous production facilities. The selection of methods for diagnosing professionally important qualities of personnel for work at hazardous production facilities of the oil refining industry of the Republic of Belarus was carried out using the example of the profession of an operator of technological installations. A model has been developed for assessing the professional suitability of personnel based on fuzzy inference systems. The architecture of an information system for assessing the professional suitability of personnel for work at hazardous production facilities of the oil refining industry of the Republic of Belarus is proposed.

The technology of installation of breast implants in the subpectoral space while preservation attachment of the abdominal part of the pectoralis major muscle

The paper describes the technology of installing breast implants in the subpectoral cellular space while maintaining the attachment of the abdominal part of the pectoralis major muscle and evaluate the results of its application. A retrospective analysis of the results of primary breast augmentation in 762 patients operated by the authors in 2010–2020 was carried out.The space for the breast implant was formed following a certain sequence of actions. The boundaries of the receptacle were: inside – the place of attachment of the pectoralis major muscle to the sternum, outside – the abdominal part of the pectoralis major muscle and the pectoral fascia, passing to the bundles of the anterior serratus muscle, at the top – thoracoacromial vascular bundle, below – VI rib and fascial node, formed by the transition of the thoracic fascia and the aponeurosis of the abdominal part of the pectoralis major muscle to the anterior wall of the sheath of the rectus abdominis muscle. Conclusions. 1. The technology of installing implants in the subpectoral cellular space, while maintaining the distal attachment of its abdominal part, allows achieving the stability of the position of the implants and avoiding rotation and malposition of the implants. 2. In terms of up to 3–4 months after surgery, a higher location of implants on the chest is often observed. 3. The decision on the need and degree of mobilization of the abdominal part of the pectoralis major muscle should be made individually. 4. The technique cannot be used when the width of the implant base exceeds the width of the pectoralis major muscle at the level of the IV rib, and, therefore, limits the choice of larger implants.

Online Multiphase Flow Measurement of Crude Oil Properties Using Nuclear (Proton) Magnetic Resonance Automated Measurement Complex for Energy Safety at Smart Oil Deposits

The necessity of a flow express control of oil dispersed system (ODS) properties, such as crude oil, oil products, water–oil emulsions, and polluted waters, is substantiated. This control is necessary for the production and preparation of oil for transportation through the pipeline and oil refining, oil products, and wastewater treatment systems. A developed automatic measuring complex (AMC) is used to implement the concept of digital oil deposits. The primary measuring device is a relaxometer developed by us based on nuclear (proton) magnetic resonance (PMR). The design and operation algorithm of the AMC and the relaxometer are described. Equations have been developed to determine the ODS characteristics using the measured PMR parameters. This makes it possible to determine the flow rates of crude oil, the concentration of water in the oil, the concentration of asphaltene, resins, and paraffins in the oil, as well as the density, viscosity, and molecular weight of the oil. Additionally, it is possible to determine the dispersed distribution of water droplets in emulsions in oil production and treatment units. Data on this distribution will improve the management of separation processes. It has been established that the implemented control of multiphase ODS using PMR parameters (relaxation times, populations of proton phases, and amplitudes of spin-echo signals) makes it possible, using AMC, to assess the consumption of electricity in technological processes at the digital oil deposits, as well as during the transportation of oil and oil products through pipelines. AMC makes it possible to reduce electrical energy consumption in technological installations and reduce pollution emissions into wastewater. The advantages of using the developed AMC are shown in examples of its application. Such as an assessment of the influence of the gas factor on electricity consumption during oil transportation through pipelines or compensation for the additional moment of resistance on the shaft of the submersible motor, which is caused by surface tension forces at the interface of water droplets in the emulsion.

Gentle Driving of Piles (GDP) at a sandy site combining axial and torsional vibrations: Part II - cyclic/dynamic lateral loading tests

Gentle Driving of Piles (GDP) is a new technology for the vibratory installation of tubular (mono)piles. Its founding principle is that both efficient installation and low noise emission can be achieved by applying to the pile a combination of axial and torsional vibrations. Preliminary development and demonstration of the proposed technology are the main objectives of the GDP research programme. To this end, onshore medium-scale tests in sand have been performed on piles installed using both impact and vibratory driving methods (including GDP). While the results of the installation tests are presented by Tsetas et al. (2023), this work focuses on the post-installation performance of GDP-driven piles under a sequence of slow/large-amplitude (cyclic) and faster/low-amplitude (dynamic) load parcels. The field data point out the influence of onshore unsaturated soil conditions, which result in complex cyclic pile stiffness trends due to the interplay of pile–soil gapping and soil’s fabric changes. The pile stiffness under small-amplitude vibrations is strongly correlated with the previous response to large load cycles, and noticeably frequency-dependent for load cycles with a period lower than 1 s. Overall, the post-installation performance of GDP-driven piles appears to be satisfactory, which encourages further development and demonstration at full scale.

Focus is on the installation performance of GDP-driven piles, which is discussed with the aid of structural and ground monitoring data. The comparison between piling data associated with GDP and standard axial vibro-driving points out the potential of the proposed installation technology, particularly with regard to the beneficial effect of the torsional vibration component. The findings of this study encourage further development of the GDP method and its future extension to offshore full-scale conditions.

Дослідження ефективності схеми керування напругою конденсатора уніфікованого регулятора якості електроенергії для зменшення коливань напруги

This article investigated the effectiveness of using a unified power quality regulator (UPQR) to reduce voltage fluctuations in electrical networks with a rapidly changing nonlinear load. It is proposed to use a voltage control scheme on the URYAE storage capacitor based on an FIR filter in order to minimize rapid voltage changes and the flicker indicator, as well as the total coefficient of harmonic distortions in the distribution system. The final simulation of the study is carried out using MATLAB/Simulink. To demonstrate the effectiveness of the proposed control scheme, a comparison of simulation results with a PI controller is made from the point of view of improving the specified power quality indicators. The initial data for performing calculations of voltage fluctuations are information on the parameters of the electrical network and the graph of a random, rapidly changing electrical load. Rapidly changing loads cause rapid changes in the network voltage, the amplitudes of which can reach unacceptable values, for example, in the case of frequent start-ups of an asynchronous motor with a large starting current. Voltage fluctuations can also be caused by technological installations, the operation of which is accompanied by active and reactive power surges , such as the drive of reversible rolling mills, arc steel melting furnaces, contact electric welding installations, etc. The main task of the research is to improve the quality of electricity, and, as a result, to increase the service life of electrical equipment and to ensure the conditions for the normal technological process of electricity consumers. Indicators characterizing voltage fluctuations were quantified: voltage change range (δUt) and flicker indicator (Pt). The effectiveness of the new capacitor voltage control scheme for reducing higher current harmonics compared to the classical one based on the PI-regulator is verified.
