QM-1 Coal Gasifier

      • Power】: 

        7.5-55(kw)

      • Coal gas output】: 

        4-30(t/h)

      • Application range】:  it is widely applied to steeling rolling furnace, annealing furnace, forging furnace, glass furnace, aluminum melting furnace, copper furnace and ceramic furnace. 

Advantages

Wide application, energy-saving and environmental friendly;

By adopting special pogada heat-resistant furnace grate, furnace grate will be protected by coal slag forever. With strong slag-breaking, slag-loosing and ventilating function. 

QM-1 coal gasifier has no coal type limit, can apply almost any kind of coal; continuous coal gasifier can adopt crude coal, spray coal, particle coal, bitumite and anthracite. 

QM-1 coal gasifier is characterized by uniformity in the respect of coal adding, slag removing and air distributing. With simple operation, convenient regulation, reliable running. 


QM-1 Coal Gasifier

This series of coal gasifier is developed based on dry type coal ash removal coal gasifier. It absorbs advantages of dry type coal gasifier and adopts patent ash removal system. With special device, coal ash can be discharged automatically. It is new generation energy-saving equipment launched by our company. It holds strong slag breaking, slag loosing and ventilating function, which can totally remove the concept that coal gasifier is pressure vessel. Furnace temperature can be controlled automatically. 

Working Principle

After screening, coal which meet gasification standard will be charged into coal gasfier. Self-produced steam will be blown from furnace bottom and mix with air used as gasification agent. After physical chemical reaction, coal will produce combustible gas. At upper stage, coal gas will be filtered by cyclone and electric tar precipitator. At lower stage, dust in coal gas will be removed by cyclone dust collector. After mixing, coal gas will be conveyed for customer’s use. it is widely applied to steeling rolling furnace, annealing furnace, forging furnace, glass furnace, aluminum melting furnace, copper furnace and ceramic furnace.
