Design & Fabrication of Coal Gasification Plant Prototype - Blogger

The steam is generated on the surface of the gasifier because of the heat transfer from the gasifier reactor to the water jacket. The steam produced from water jacket is 10 kg. Syn gas produced from 1 kg coal = 2.156 + 0.82 + 0.0056 - 0.011 = 2.13 kg. Syn gas produced from 5 kg of coal =10.65 kg /h.
