In order to compare and analyze the effects of different types of MSW incineration on power generation performance

a system model of waste incineration power generation process was constructed using Aspen Plus based on a900 t/d waste incinerator with 3 different types of medium-temperature and medium-pressure type steam turbines. Under the rated working conditions

2 different types of MSW were selected as fuels for incineration

and the flue gas temperatures under different excess air coefficients were compared to study the power generation of the 2 fuels; by using 2 other steam turbines with different parameters

the power generation was compared and analyzed. The results showed that the MSW with high calorific value increased the flue gas temperature and the thermal efficiency of the unit. The difference in flue gas temperature between the two MSW fuels was 167.7 ℃; and it increased the steam turbine brake horsepower by 58.6%

which had a significant improvement on the steam turbine brake horsepower. A certain value of the excess air coefficient causes the percentage of combustible components in the flue gas to plummet toward 0. Changing the steam parameters changes its brake horsepower. The waste fuel selected has a significant effect on the power generation efficiency of the waste incineration system

the lower the water content and the higher the fuel calorific value the higher the efficiency; as the excess air coefficient increases

the combustion is adequate

but the flue gas temperature gradually decreases; the steam parameters of the steam turbine have a significant effect on the generator brake horsepower

up to a 10.63% decrease in brake horsepower.
