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 $SO_2 gas, since the large portion of sulfur contained in anthracite is remained in the ash with a form of sulfide and sulfate. Under this experimental condition, however, it was observed that the SO_2$ gas corresponding to about 20 % of sulfur content in anthracite was released at $1000^{\circ}C$.

無煙炭의 燃燒에 있어서 $SO_2 가스의 發生을 抑制하기 위하여 小量의 알칼리 혹은 알칼리 土金屬의 水酸化物을 添加 시키는 것이 效果的이라는 것을 알았다. 그것은 燃燒時에 無煙炭中의 黃分의 大部分이 黃化物 혹은 黃酸鹽의 形態로 炭分中에 固着되기 때문이라고 생각된다. $1000^{\circ}C$로 加熱할 때는 添加劑를 가한 無煙炭中의 黃分의 약 20%가 SO_2$ 가스로 發生한다.
