Coal Gasifier
Feed Size : 800mm
Capacity : 140-350Nm3/h
Application Fields : Coal Gasifier is widely used in machinery, metallurgy, building materials industries such as heating workshop with hybrid generator gas equipment
Introduction : The main features are less investment, easy operation, safe and convenient to run. This machine can save 20% fuel than burning coal directly and save more than 60% than furnace with oil fuel.
Coal Gasifier designed by Hongji is advanced equipment for producing mixed gas with water and steam as gasifying agent.This machine is applicable for gasifying fuel like coking coal or coke. Coal Gasifier is widely used as heating furnace in mechanical metallurgy, chemical, glass, construction, light industry, food and textile industry.
Coal gasifier characteristics:
The main features are less investment, easy operation, safe and convenient to run. This machine can save 20% fuel than burning coal directly and save more than 60% than furnace with oil fuel. It has remarkable smoke prevention and dust control effects, which is the important equipment in heating system and has reached enviroment protection requirement.
Coal gasifier working principle:
Solid fuel can be gasified into combustible gas with vapour medium. Because the vapour medium is mixture, the output is mixed combustible gas which is called mixed gas. Hot gas produced after primary dust removal is conveyed to gas heating furnace nozzle and erupts firing, with the oxygen supply of hot air conveyed from hot air pipe around the furnace, which generated high temperature to heat the furnace and reach the furnace��s required heat value. The temperature is very even because the innar fuel is gas. This furnace is widely used as different types with certain temperature range including steel rolling furnace, annealing furnace, forging furnace, steel pipe furnace, glass furnace, aluminum melting furnace, copper furnace, ceramic furnace, etc.
