• Abstract

Energy audit plays key role in identifying energy conservation in the industrial sector. They help to identify various energy losses to find solutions to avoid such losses. In this project concentration is focused on the heat loss due to dry flue gasses. To accomplish the task Kottagudem Thermal Power Station (KTPS) VI Stage is selected. This power plant is 1×500 MW capacity, coal fired. The steam generator is Single Drum, controlled circulation, rifle tube, radiant, single reheat, dry bottom, two pass, and balanced draft, out door. The various parameters of the selected power plant boiler were measured such as fuel consumption, steam pressure, steam temperature, Gas Calorific Value of fuel (Coal) used, fuel proximity analysis, flue gas temperature, flue gas analysis etc. The losses were found out using traditional heat transfer formulae. The main objective in these theses is to find the losses due to dry flue gasses and to reduce the heat loss by introducing a modern type soot blower which has a special feature when compared with the existing one and proposing some of the methods to improve the performance. It is suggested that by introducing special modern soot blower and by changing the blowing medium i.e. from Steam to Water the heat loss can be reduced from 7 % to 4.69% and there by the efficiency of the boiler can be improved. The introduction of the suggested modern soot blower is a difficult task and is costly procedure. But the modernization is must for the future scope to meet the demands and annual monetary savings of the thermal power plant.
