ABSTRACT:
A method is disclosed for initiating operation of a coal gasification plant which includes a gasification reactor and gas cleansing apparatus fabricated in part from materials susceptible to chloride induced stress corrosion cracking the presence of oxygen. The reactor is preheated by combusting a stoichiometric mixture of air and fuel to produce an exhaust gas which is then diluted with steam to produce product gas which contains essentially no free oxygen. The product gas heats the reactor to a temperature profile necessary to maintain autothermic operation of the gasification process while maintaining air oxygen-free environment within the plant apparatus while chlorine is liberated from coal being gasified.
