Henan Hongji Coal gas producer for steel furnace is the process of producing syngas–a mixture consisting primarily of methane (CH₄) carbon monoxide (CO), hydrogen (H₂), carbon dioxide (CO₂) and water vapor (H₂O)–from coal and water, air and/or oxygen. Historically, coal was gasified using early technology to produce coal gas (also known as "town gas"), which is a combustible gas traditionally used for municipal lighting and heating before the advent of industrial-scale production of natural gas.

A Main body

B Coal load system

C Blower system (the steam mixed with water, blow in to the coal gasifier with blower)

D Ash discharge (rotation wet type auto discharge, no pollution to the enviroment)

E Dust collect system (water seal dust collect)

F Control panel (motor control, humidity instruction, power source together controlled)

G Computer control system (optional)

H Steam system (hot steam recycle, water & steam separator, self relief device, control valves, pump etc.)

I Operation platform(steal structure, for the worker inspection the coal gasifier.)

•  Ash layer: the coal come down from the top, the gas agent go up from the bottom.
•  Oxide layer: also called burning layer, thermal chemical reaction, the O with heat in the air reaction to become CO2, release heat.
•  Reduction layer: the coal after heat and together with steam complex reaction become to CO, H2,CH4, O2,CO2,N2 etc, and release heat.(CO2+C→CO↑, H2O+C→H2↑+CO).
• Carbonization layer: under 400-500℃, the volatile and other materials come out, the coal become to coke, the coke come to the reduction layer for chemical action.
•  Dryer layer, to dry the coal gas.
