Product Details

Two-stage Coal Gasifier

Two-stage coal gasifier produces gas by burning coal

It has two gas outlets, the upper gas outlet and lower gas outlet, upper gas contains tar, which can be disposed by

electric oil remover and recycled, lower gas contains no tar, dust of which can be cleaned by cyclone dust collector

All the gas produced are cooled indirectly and the waste water is condensed liquid sewage, which reduces the disposing

amount of waste water containing oil and phenol

Waste water and tar are stored in steel containers to prevent harmful substances from evaporating or leaking

Waste water can be disposed by combustion

The coal gasifier reduces cost and increases profit as a result of energy-saving, because of burning gas, it is able to comply with the environment protection standard

Applications: heating furnace fuel in metallurgy, construction materials, glass industry; raw materials and fuel in chemical industry
