Two-stage coal gasifire produces gas by burning coal. It has two gas outlets, 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 protecing standard. Now that the prices of energy increases and the environment protecing requirements are stricter, this kind of coal gasifier should be your best choice.
