Effects of Gasification Parameters on Performance of Gasification Based on Two-stage Coal-slurry Gasification

Gasificatio island based on two-stage coal-slurry gasification is established using software ThermoFlex.Gasification parameter that effects gasification performance of two-stage coal-slurry gasification are analyzed,and effect of two-stage coal ratio on gasification performance is studied.The results show that as two-stage coal ratio increases,effective gas content decreases,and cold gas efficiency firstly increases and then decreases.There is an optimal value of two-stage coal ratio.Considering gaqsification temperature and cold gas efficiency,the optimal two-stage coal ratio is 0.1 ~ 0.15.
