1.single-stage coal gasifier, 2.Burning temperture: above 1200 degree, 3.Low consumpt, 4.small gasifier - details see: https://www.machineto.com/2011-china-professional-gasifier-manufacturer-10366877

The single section gasifier is also called single section gasifier. It is manufactured by adopting the long points of various similar enterprises and is consequently advanced in design and reasonable in construction. Two kind of slag/ash discharging methods are adopted, i.e. discharging slag with wet ash pan driven by worm and worm gear or removing ash with water-seal jacket equipped with screws driven by conical gear, both of these two methods are stable and reliable in operation. The furnace body adopts the complete water jacket structure. The self-produced steam can satisfy the requirement of both coal gasification and steam sealing for poking hole. Coal-feeding adopts manual or electrical drum-type double bell jars.


According to different supportive purification equipment of single section gasifier, it can be divided into hot gas station and cold gas station.
Process flow of single Hot Gas Station,Saturated air,which is formed by self-produced 0.294MPa steam and air from blower, isused as gasifying agent and comes into gasifier from the bottom via a check valve. Block coal is broken up and filtrated to size of 13-25mm or 25-50mm. Then the coal is fed into coal bunker by coal feeding system and be fed into stove. Gas produced by stove is removed dustsby gravitational dust cleaner and cyclone dust cleaner and finally be send to user.

arameters and appearance of the product is subject to change without prior notice. The Suffix letter “G” after the model stands for the high air pressure stucture of the gasifier.
