In the combustion process, it is found that the addition of small amount of hydroxide of alkali and alkaline earth metal to the anthracite is more effective in order to suppress the evolution of SO2 gas, since the large portion of sulfur contained in anthracite is remained in the ash with a form of sulfide and sulfate. Under this experimental condition, however, it was observed that the SO2 gas corresponding to about 20 % of sulfur content in anthracite was released at 1000℃.
