The model of a 400 MW IGCC power plant was established by using the commercial software GT PRO.On the basis of accuracy verification of the gasification model

the effects of reaction temperature

coal slurry concentration and oxygen purity on syngas composition and performance of the IGCC power station were investigated.the results show that

with an increase in reaction temperature

the cold gas efficiency and power efficiency decreased

while the plant net power output increased.Increasing both the coal slurry concentration and oxygen purity were beneficial to enhance the cold gas efficiency and power efficiency but decrease the plant net power output.According to the influencing degree

the order of the above three influencing factors was: coal water slurry concentration

reaction temperature

and oxygen purity.
