Gasifiers an overview ScienceDirect Topics

An entrained flow gasifier operates at a much higher temperature than a fluidized bed gasifier (it is more like a pulverized coal furnace) and requires more oxygen but also produces a higher-quality gas product. After gasification the product gases must be cleaned to remove dust,

During gasification, the coal is blown through with oxygenand steam (water vapor) while also being heated (and in some cases pressurized). If the coal is heated by external heat sources the process is called "allothermal", while "autothermal" process assumes heating of the coal via exothermal chemical reactions occurring inside the gasifier itself. It is essential that the oxidizer supplied is insufficient for complete oxidizing (combustion) of the fuel. During the reactions ment
