two-stage coal gasifier, coal gas generator
coal gasifier, coal gas generator
Brief introduction:
Because of burning gas, it is able to comply with the environment protecting standard. Now that the prices of energy increases and the environment protecting requirements are stricter, this kind of coal gasifier should be your best choice.
The main types : Φ2.0m, Φ2.6m, Φ3.0m, Φ3.2m, Φ3.6m.
Working principle:
Two-stage coal gasifier produces gas by burning coal. It has two gas outlets, ie, 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.
Application:
it is widely used in the environment-friendly and energy-saving technological renovation of gas-processing heating furnace, gas forging furnace, gas crucible furnace, gas mold furnace, grilled ladle gas furnace, sand resin heating gas regenerator, glass melting gas furnace, ceramic gas furnace, smoke exhausting refractory kiln and tunnel kiln, as well as the renovation of furnaces that burn coal or oil, kilns, and equipment that needs heat such as metallurgy, chemical industry, alumina, fire-resistant materials, glass products and existing kiln, with very good effect, ect.
