Energy Analysis and Efficiency Assessment of Water Tube Boiler

Abstract

Energy is most precious thing, so it can be used most efficiency way. Most types of energy now a day's use in form of electricity, which is mainly generated in steam power plant and rest of source are wind, hydro and solar. The heart of steam power plant is boiler and to maximize efficiency of power plant, there is need to increase efficiency of boiler. The boiler efficiency can be evaluated by direct and indirect method, in direct method the energy gain by working fluid is compared with energy content of fuel while in case indirect method various losses compared to the energy input. Present work is concern on energy analysis and efficiency assessment of water tube boiler for sugar industry. By using catalyst what kind of effect on exhaust gas, combustion quality, environment friendliness, economy and up to what extent efficiency increase. By increasing boiler efficiency one can save fuel input to power plant and also earn carbon point and can increase profit to plant. From considering overall analysis and results it is concluded that, the pre boiler efficiency measured by O2 gas analyzer remains same as defined value without using solid combustion catalyst. It also shows that the efficiency of the pre-boiler leads to increase of the order of 2.82%, 2.86%, 2.35% and 2.4% related to four different observed boilers with use of solid combustion catalyst, which is more supportive and required for the reduction of cost. The overall 2.61% improvement in the boiler efficiency as well as 3.3% reduction in baggase consumption. The overall saving of rupees 41, 19,000 with this efficiency is done after using the catalyst.
