We know that coal is a solid fuel. Coal is a major energy source in India. There are some disadvantages in using solid fuel for combustion. We can overcome these disadvantages by converting coal to combustible gas.

The advantages of coal gasification and a little idea about coal gasification is discussed. Moving bed, fluidized bed and entrained bed gasifiers are some of the gasifiers. spouted bed gasifier is a distinct method of contacting solid and fluids. An experiment is conducted in a spouted bed gasifier with coal of free swelling index 0, 4 and 7 are tested. Gases of heating value up to 3.61 MJ/m3 were produced at atmospheric pressure and temperatures to 9300 C. Characteristics of spouted bed gasifiers are presented. Applications and modifications are included.
