Selling XH2Q Hot-detarring Gasification Furnace
Double 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 gasifier is higher than that of produced with XH1Q series and it has better environmental protection performance. Big carbonization sectional area and coal storage, slow coal bed lowering and long carbonization time. Simple structure,convenient maintenance and small investment.
Structure characteristics:
Coal feeding section: Practical and reliable coal-level detector cooperates with stoker to realize automatic coal feeding and guarantee coal gasifier is full charge layer operation.
Pyrolysis section: Furnace lining’s inside:This structure was designed after the strict calculation of heat transfer and heat exchanger, which can improve heat transfer efficiency. So thar the coal can be dried and carbonized fully and effectively in this section, as well as the volable matter can be pyrolysised and it will mix in the gas to improve the gas calorific value. Also it is helpful for the gasification of lower gas.
Gasifying 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.
Technical Process of XH2Q Hot Detarring Coal Gasification Equipment
The gas at upper section enters an electrostatic precipitator at the operating temperature of 90~150ºC. The tar fog drops and dust in the gas are polarized, gather to the wall of polar pipe and flow to tar tank by itself. The gas at lower section is removed with large-particle dust through a dust hopper, enters a cyclone dust collector for centrifugal dust collection, and the dedusted gas has the temperature of about 450~550ºC. The gas at upper section and lower section is mixed and delivered to a heating furnace through a gas delivery pipeline.
