Single Stage Coal Gasifier

QM Series single stage coal gasifier is developed on the basis of dry-ash bottle ash handling gas stove, it learned the dry-ash handling characteristics, and uses a patented rotating ash tray Cleaner, automatic slag institutions, I introduced a new generation of intelligent energy efficient environmentally friendly products.
Coal gasifier Characteristics: 
special pagoda-shaped heat-resistant iron grate, furnace wall always protected by slags,Powerful broken slag, loose the slag, breathable role, Fundamentally eliminate the gas stove is the concept of pressure vessels, Realize the heating furnace temperature automatic control.
Operating Principles: 
continuous coal gasifier use 10-80mm pea coal as ideal fuel, which largely increases the gasification intensity, accelerate the gasification reaction, improves the gasification rate of coal, and makes charcoal react with vapour to form combustive air such as carbon monoxide and hydrogen, so as to reach complete gasification ,produce gas continually and steadily.
Environment-friendly Target:
As was testified by Henan Environment Testing Centre, it has no smoke when the coal is burned and the discharge amount of both sulfur dioxide and soot complies with the GB9078-1996 environment-friendly standard.
Safe and Reliable: 
continuous type coal gasifier uses national invention patent technology, eliminating the hidden trouble of traditional coal gasifier easy explosion.
Without being limited by the coal:
continual coal gasifier can use varieties of smoke run coal such as raw coal,powder coal ,pea coal, or anthracite coal(pea coal whose powder less than 30% is ideal fuel).
Using a dedicated inflamer: 
The furnace is equip with special ejected inflamer according to different specification and different using condition,having the advantages of use flexible, burning sufficient, functioning stable, useful time prolonged and so on.
Reducing Labor Intensity:
traditional coal gasifier need poking the fire over ten times to test the condition inside the furnace and prevent coking, which not only increases the labor intensity but also damages people's health. Continual coal gasifier solved all these problems.
Serviceable Range: 
Because the furnace has broadened coal sorts used and reduced producing cost, 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,glass melting gas furnace, ceramic gas furnace, smoke exausting 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, aluminum, fire-resistant materials, glass products and existing kiln,with very good effect.
