Product Description

The Environmental Protection and Advanced Technology Two-stage Coal Gasifier Widely Used in A Variety of Industries


Two-stage Coal Gasifier produce gas is divided into the upper section of the gas and the gas.Gas in the upper class I advanced electric tar precipitator, and dust removal heavy tar, its working temperature is between 90-150 degrees Celsius, in indirect cooler, gas bai in indirect cooler cooling to 35 to 45 degrees Celsius.The period of gas by the cyclone dust removal, dust removal after the temperature is around 450-450 degrees Celsius.Then enters the waste heat exchanger, while for gas cooling recycle gas sensible heat, gas temperature dropped to 200-230 degrees Celsius;Again into the air cooling device cooling, the temperature dropped to 35 to 45 degrees Celsius.After being indirect cooling of gas in the upper and the lower section of the gas into the secondary electric light oil traps again to take off the oil and dust removal.After cooling and purification of the gas by pressure and pressure, used by the gas pipeline.

Advantages of Our 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.

Structure Characteristics of Coal Gasifier


Coal feeding section: Practical and reliable coal-level detector cooperates with stoker to realize automatic coal feeding and guarantee coal gasifier is in full charge layer operation.

Pyrolysis section: Furnace liningGasifying section: Water jacket structure is adopted and self-produced steam is used for gasification.

Coal feeding mechanism: Advanced upper roller, middle flashboard and lower bell jar mechanism is adopted, which is characterized by simple operation, easy maintenance and good gas-tightness.

Slag collecting mechanism: Wet slag removal from both sides is made by ratchet wheel & detent with hydraulic drive. Self-designed plough-type special plate is adopted for slag removal, which is characterized by steady drive and smooth deslagging. Our plough-type plate has been used in many types of domestic and imported coal gasifiers and is well received.

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.

Two-stage coal gasifier is specially designed for gasifying bituminous coal, by which light tar can be carbonized out from coal in pyrolysis section. The gas calorific value produced with this type is higher than that of produced with KM1Q series. Also it has better environmental protection performance. Big carbonization sectional area and coal storage, slow coal bed lowering and long carbonization time make coal carbonized completely.


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 , the heat energy utilization rate is extremely high.
