Double stage coal gasifier, mechanicak coal gasifier, gasifier with good permeability coal gasifier with environmentally
Double stage coal gasifier
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.
Features:
1 It is with high and stable calorific, large elasticity of operation, high degree of automation, low labor strength
2 Two-stage coal gasifier do not make environmental pollution, significantly saving water, covering small area, low cost for long term operation.
3 According to different customers’ requirements, we can use mechanical or hydraulic, with good permeability effect. It is suitable for bituminous coal gasification process.
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.
