Single Stage Coal Gasifier
Coal Gasifier features: 1.Easy to operate 2.Heating uniformity 3.Supply gas continuously and steadily Composition of Single Stage Coal Gas:CO: 23-27% H2: 12-17% CH4: 2-3.5%CO2: <5%N2: 50-54%
Crude Coal Gas Technics of Single Stage hot gas station:
Single stage coal gasifier generater coal gas with the temperature from 450-550 °C, after that it goes into the gravity dust collector to remove dust and tar, after that coal gas go throught the cyclone dust collector for secondary cleaning, then coal gas was transported to use.
