About product
Circulating Fluidized Bed Coal Gasifier utilize the entire height of tall vessels for gas–solids contacting, with no distinct interface between bed and freeboard. The corresponding flow regime is usually fast fluidization for combustion and gasification of solid fuels. Operating conditions, riser geometry, hydrodynamics, heat transfer, solids feed, and particle recirculation all have a significant influence on the operation and effectiveness of the system. Circulating fluidized bed coal gasification is a clean industrial gas production technology. There is no tar in gas and no wastewater discharge.
Circulating Fluidized Bed Coal Gasifier Process
Add 0-1.2mm pulverized coal fuel from the middle of the furnace through the coal loading system, and react with 550C and 650C high-temperature preheated gasification agent (air + water vapor. Oxygen-enriched, etc., gasification agent can be flexibly selected). CO, H2, and a small amount of CH4 are generated; the unreacted ground material is returned to the furnace through the return device for a high-rate cyclic reaction; the gas is cooled to about 700C through the air preheater; the temperature is continued to continue to be cooled to about 220C through the waste heat boiler; and then After cooling and dust removal by cyclone dust collector, cooler and bag filter, it enters the desulfurization system; finally, the clean gas is pressurized and sent to the gas point. According to the different needs of users for gas, 600C -700C hot raw gas and 35C clean gas can be provided.
