Analyses of Boiler High-temperature Corrosion in a Coal-fired Power Plant Using Indonesia Coal

Indonesia coal used in a coal-fired power plant deviates from designed coal greatly due to its high-volatile components which can increase the possibility of high temperature corrosion of boiler.By combustion optimizatiom tests,sampling and analyzing O2,CO and H2S in flue gas,decreasing the reducing atmosphere in the combustion area,the high temperature corrosion caused by the change of coal had been reduced,and thus eusure the safety and economic operation of the unit had been ensured.
