The composition of the two-stage Pyrolysis hot gasification is very simple, consisting only of a coal gasifier, a cyclone dust separator, and a water seal. This process can control a higher temperature of gas, greatly utilizing the sensible heat of the gas. At high temperatures, the tar in the gas is also transported in a gaseous form to burners for combustion, significantly improving the gas calorific value and saving coal consumption.

  This process has achieved perfect results in industries such as glass and foam alkali, with an energy-saving effect of 5-10%.
