Product Description

Coal Gasifier is designed to be high production capacity, high gasification efficiency and better adaptability to various coals, high gas calorific value, and only need two worker to operate it, our coal gasifier can cope with different type heating furnace, kiln, steam boiler and ect.
Our company design and manufacture environmentally friendly coal gasifier that based on the air and steam as gasification agent and is the advanced equipment that produce mixed gas. The equipment is suitable for gasifying coking coal, coke and other fuels, are widely used as furnace kiln of machinery, metallurgy, chemical industry, glass, building materials, light industry, food, textile industry.


The features of coal gasifier
1. Small investment of the main equipment, run fast.
2. Safe and convenient using, simple operation, can save 20% fuel than direct coal.
3. Compared with the heating furnace of direct fuel, use hot gas can save energy economy more than 60%
4. Have a significant effect of smoke prevention and dust control, meet environmental protection requirements, is the important equipment of hot working system.
5. Gas outlet temperature is 400-550 ° C, the heat energy utilization rate is extremely high.
Advantages of coal gasifier
Firstly, It can raise the utilization of heat and coal can be fully burnt, so the energy comsumption can be reduced. Compared with burning the coal directly, It can save 20%-40% energy.
Secondly, By using this equipment, the temperature can reach 1500° C in the connected kiln or furnace and the temperature difference is low.
Thirdly, It is conforming to the industrial furnace emission standard GB9079.88. Slag is discharged in wet form which is free from pollution and social benefits.
Fourthly, It can greatly improve the working environment, reduce the labor intensity, so it has been well-received since it was invented.


The technological process of coal gasifier
1. In the first place, using the lift machine to add coal into the stoker, then adding coal into coal gasifier by stoker, steam and air as gasification agent from the bottom of the furnace into the bellows drum charging, coal and gasification agent oxidation, reduction at high temperature in the coal gasifier, at last, produce gas.
2. The second, gas into the gravity dust collector in the first place, use the gravity of dust for settling and conduct a preliminary dust. Then enter the cyclone, through the effect of centrifugal force to remove most of the coal powder and dust. The hot gas after a whirlwind dust removal through a number of settling chamber, partition water seal, through the hot gas pipe to the gas equipment for using.
