Qm-1 coal gasifier
This series of coal gasifiers, developing from and taking good advantage of dry-type ash disposal coal furnace,are new intelligent high-effect environment-friendly products put forward by our company, in which patent slag-removing revolving ash pan and automatical slag removing structure are used.
Coal gasifier Characteristics: special pagoda-shaped heat-resistant iron grate, furnace wall always protected by slags, strong effect of slag breaking, slag loosing and ventilation, the concept abandoned that gas furnace is the same as pressure vessel basically, heating tempreture autocontroled.
Operating Principles: continual coal gasifier uses 0-80mm pea coal as ideal fuel, which largely increases the gasification intensity, accelerates the 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 and 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 nviroment-friendly standard.
Coal gasifier Safe and Reliable: continual coal gasifier uses national invention patent technology, eliminating the hidden trouble of traditional coal gasifier's easy explosion.
Not Be Restricted by Coal Sorts: continual coal gasifier can use varieties of smoke run coal such as original coal,powder coal and peal coal, or anthracite coal(peal coal whose powder less than 30% is ideal fuel).
Using a dedicated inflamer: The furnace is equiped 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 Labour Intensity: traditional coal gasifiers need poking the fire for over ten times to test the condition inside the furnace and prevent coking, which not only increases the labour intensity but also damages people's health. Continual coal gasifier solved all these problems.
Coal gasifier Serviceable Range: Because the furnace has broadened coal sorts used and reduced producing cost, it is widely used in the enviroment-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 regenerater, 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, allumim, fire-resistant materials, glass products and existing kiln,with very good effect.
