Double Stage Cold Coal station

The gas from two stage coal gasifier is divided into the

upper one and the lower one. Upper gas temperature is

90-150℃ After the removal of heavy tar and dust by electric

tar catcher l, it goes into the indirect cooler and it is cooled

to 35-45℃ lower gas temperature is about 450-550℃ after dust removal when it goes into the cyclone dust collector first.After that, it comes into the waste heat exchanger to cool the gas and recover the heat from it and gas temperature is reduced to 200-230℃ before entering the wind cooling system where the temperature is dropped to 65-80℃ after the wind cooling process.Through indirect cooler,lower gas is cooled to 35-45℃ by circulating cooling water. After all the process, upper gas and lower gas go to the electric light oil catcher ll for second oil and dust removal.The purified gas is then pressurized and transported to user through pipes.
