Power generation potential of municipal solid waste through direct flame incinerator

Abstract

This study was carried out to assess the power generation capacity of 4 types of waste material. In this study combustion temperature, steam temperature, steam pressure, mass reduction, gaseous emission and ash content production was calculated for wood, yard, mixed and combined waste at various time interval. In this study fabricated direct flame incinerator was used. This study is based on the cycle from waste collection to waste combustion then to steam formation and further more to electricity production and at end to the gaseous emission. From the study experimental work it was obtained that the combustion of wood, yard, mixed and combined waste produced 482.2 °C, 121 °C and 35 psi as highest combustion temperature, steam temperature and steam pressure respectively at different time line for all the waste material. Moreover from combustion of wood waste produced 66g of ash content and 98.35% mass reduction was calculated. For the yard waste incineration, 54g of ash produced and mass reduction was 98.65%. While for mixed waste the amount of ash produced was 151g and mass reduction was 96.22% and similarly for combined waste, 97g of ash was obtained and mass reduction was 97.57%. The incineration treatment technology is cost effective, easy to operate as compare to other waste treatment technologies.
