The influence of regional industrial structure on the suitability of biomass energy development: A case study of 30 counties and cities in a cold region of China

The development of the biomass economy contributes to economic growth and social development. The study of biomass energy economy from the perspective of industrial structure type has the significance of promoting the optimization and upgrading of industrial structure, promoting the development of green industry and other aspects. It helps to promote the sustainable development of the economy and society. And industrial structure is a major component of the socio-economic system. Therefore, it is necessary to study the impact of material energy supply and demand from the perspective of regional industrial structure type. The objective of this study is to explore the relationship between the type of industrial structure and the development of biomass energy from the perspective of the economic direction, so as to fill the gap in this research perspective. Based on the three major industries generally regarded to constitute GDP - agriculture, industry, and service - the regression results of STATA software were used to calculate biomass potential according to crop distribution status. Using the ArcGIS analysis tool, the biomass break-even model related to resource supply-demand has been used to obtain the break-even status of the research area under six industrial structures in the past 20 years. According to research results, the break-even degree of biomass energy supply is between 0.109 and 1.236 when the industrial structure types of counties and cities are service-agriculture-industry and industry-agriculture-service. This is suitable for biomass energy development. When the industrial structure type of counties and cities is service-industry-agriculture, the break-even degree of biomass energy supply is between -0.428 and 0.277, which is not suitable for biomass energy development.

Research on the Linkage between Land Consolidation and Rural Industrial Development Based on Land Spatial Planning

Under the background of the rural revitalization strategy, rural industries are gradually developing in the direction of spatial stratification and product diversification[1]. As a carrier of space, land is naturally inseparable from land consolidation to realize the reconstruction of industrial space. Based on the situation of adapting to the new stage of rural transformation and development, under the framework of land spatial planning, this paper explores the governance advantages of organic connection between land consolidation path and rural industrial development. Nan'an Town, Wenshui County, Shanxi Province, a typical demonstration area of industrial transformation under the land consolidation strategy, was selected as a research case, and comprehensively discussed from the perspective of industrial restructuring and spatial reorganization under the role of land consolidation. While continuously promoting its characteristic pear orchard industry, combined with land consolidation suitable for local industrial development, the site has built a new type of industrial structure at the village scale, replacing the traditional primary industry with characteristic industries, and gradually extending and expanding on this basis. At the same time, the industrial space reorganization was realized through land consolidation, and the "production-life" composite space and the "production-ecology" composite space were gradually formed, and the transformation and development of the countryside was realized. Land consolidation and rural industrial development promote each other, linkage development, the resulting economic benefits, social benefits, ecological and environmental benefits are obvious, the current rural economic development and land consolidation reform will have a positive reference and demonstration effect.

Advantages of Pre-Engineered Building over Conventional Building

In these days, the cost and time of construction is in more priority for the client with the large working area for various uses. For the economically and minimum loss of material, pre-engineered building system (PEBs) has many advantage, because it gives more column free space at low cost. Pre-engineered metal buildings are more reliable for various uses like complex industrial facilities, warehouses and distributioncenters, stock-house, shopping malls, resort, motor court, office, cabin, service complex, aircraft-hanger, athletics and fun stadium, study places, temples, hospitals, and any types of industrial structures. In the pre-engineered metal building system, the rigid frame consists of slab, wall are connected with primary member (beam and column). This frame can spanlarge spacing without any intermediate columns. The frameswidths are spaced at spacing between 15 m to 60 m and span can increase with column-free up to 300 m in proposed building structures. Therefore in this paper, an attempt has been made to analyze a pre-engineered metal building with a span of 40 m with the help of finite element based software ETABS (2013). For the comparison, for the same span of 40 m length a conventional steel building is analyzed in same software. The results were found from both analysis indicated the pre-engineered steel building is economic with the conventional steel building as well as stablealso.

Problems encountered when assessing the technical condition of some types of industrial structures on the example of coal bunkers for a power boiler

The assessment of the technical condition of the structure in industrial facilities is sometimes very difficult, even for experienced construction specialists. First, this applies to facilities in which there are quite specific cubature constructions, as objects located in the coal mine facility, or coal-fired CHP plants. In the case of energy plants, such a typical construction that causes the most problems when assessing the technical condition is coal or fine coal storage tank usually in the form of bunker batteries supplying power boilers. In practice, access to the interior of such bunkers is possible only when the power unit is put out of service (boiler extinguish) in order to repair, upgrade or expand it. In presented paper on the example of two coal bunkers (from a battery consisting of four such constructions) of one of the power plants located in southern Poland, the authors want to present and discuss some specific problems that occurred in the assessment and analysis of the technical condition of this type of specific industrial structure.

Application of Terrestrial Laser Scanning to Study the Geometry of Slender Objects

Slender objects are a special group among the many types of industrial structures. These objects are characterized by a considerable height which is at least several times bigger than the diameter of the base. Mainly various types of industrial chimneys, as well as truss masts, towers, radio and television towers and also windmill columns belong to this group. During their operation slender objects are exposed to a number of unfavourable factors. For this reason, these objects require regular inspection, including geodetic measurements. In the paper the results of geodetic control of geometry of industrial chimney with a height of 120 m has been presented. The measurements were made by means of terrestrial laser scanning technique under rather unfavourable conditions (at night, during snowfall, with low air temperature) which allowed to verify the real usefulness and accuracy of this technique in engineering practice. On the basis of point cloud, the values of deviations from the vertical for main axis of the chimney have been calculated. Using point cloud, the selected horizontal cross sections of chimney were analysed and were compared with the archival geodetic documentation. On this basis the final conclusions about the advantages and limitations of the using of terrestrial laser scanning technique for the control of geometry of high industrial chimneys have been formulated.

Seismic analysis of an asymmetric fixed base and base-isolated high-rack steel structure

Since, in the case of plan-eccentric, externally-braced, high-rack storage structures made of steel, damage to the central part of the structure can cause damage to the stored goods, and thus higher earthquake-induced costs, an investigation has been performed into the seismic performance of such structures. An actual structure was analysed both as a fixed base variant, and as a base-isolated variant. The extended N2 method (pushover analysis) was used, and the results obtained were compared with selected results obtained by nonlinear-dynamic analysis. The response of several different mass-asymmetric structural variants, corresponding to different occupancy levels of the structure, was analysed, and the results obtained are presented as floor plan projection envelopes of the top, relative and base displacements, as well as the storey drifts. An interesting result obtained in the research was that asymmetry can increase the damage in the supporting structure on the flexible side, and that the central part of the rack structure remains in the elastic region only when the eccentricity is small. In fact, from the seismic point of view, full occupancy is not the most critical condition, but rather lower occupancy, which could cause eccentricities ranging up to 10% or 15% of the larger floor plan dimension; this could lead to damage propagation in some of the columns. The application of base isolation has a positive effect on the management of seismic performance, even in the case of higher levels of occupancy and larger mass eccentricities. It is pointed out that an eccentricity of 5%, which is prescribed in Eurocode 8, might not be sufficient in such structural types, and that similar concerns could be present in other types of industrial structures with a similar ratio between live and dead loads.

Pump-set clusters in China: Explaining the organization of the industry that revolutionized Asian agriculture

This paper studies the pump-set industry in rural China, which has led to the widespread diffusion of inexpensive and readily repairable pumping technology in countries such as Bangladesh, Pakistan and Viet Nam. To do so, we first describe the rise of China’s pump-set industry, which includes hundreds of small family-owned enterprises that are doing business in a manufacturing cluster located in a single small town in southern China. We then discuss the advantages and disadvantages associated with this type of industrial structure. We conclude by examining the dynamics of the industry that have emerged during the past decade and speculate on future developments of China’s pump-set industry and the ways that it may continue to support the further expansion of food production in Asia.

A planning‐level model for estimating quantities of wastes generated by the demolition of structures during remediation

AbstractA model is presented to estimate quantities of wastes generated by the demolition of various types of industrial structures. It is intended to be used for preliminary planning purposes in the absence of any detailed structure‐specific information. Detailed material quantity estimates compiled for structures at the U.S. Department of Energy's Fernald site in Ohio were used to develop the statistical relationships in the model. The model provides estimates of the total quantity of wastes, the quantities of waste concrete, and the quantities of wastes that originate from at‐, below‐, and above‐grade portions of a structure.

Earthquake Protection Through Seismic Isolation

The basic problem in designing earthquake-resistant low- to medium-rise structures it that their fundamental frequency of vibration is in the range of frequencies where earthquake energy is the strongest. The building, therefore, acts as an amplifier of the ground vibrations, with the floor accelerations increasing over the height of the building. The goal of the seismic design should be to reduce the accelerations in buildings to below the level of the ground accelerations. To do this the building must be flexible.the necessary flexibility can only be achieved by using base isolation at the foundation level. After a slow start the use of isolation is increasing rapidly in the United States for buildings, retrofit, bridges, and certain types of industrial structures. The concept was met initially by considerable skepticism by the structural engineering community, but is now on the leading edge of seismic design and is being selected where levels of earthquake protection beyond code minimums are required.

Use of rock breakers for shattering concrete masses at the Dneprogés-II hydroelectric plant

1. Experience with more than four years of operation of rock breakers has demonstrated that they can be successfully used for construction and repair work under any conditions, near transmission lines, existing equipment, residential buildings, and bridges, without removing people and equipment from the work zone and without interrupting the parallel technical processes. 2. The use of rock breakers is especially effective for the reconstruction of different types of industrial structures where it is necessary to destroy old foundations, masonry, and concrete masses.
