The results show that in the high temperature zone of coal combustion and gasification elemental mercury is thermal stable form of Hg.

化学热力平衡分析结果表明，在煤燃烧和气化的最高温度区域里，单质汞是汞的主要形式；

Drying, low-temperature carbonisation, and cracking of gases occur in the upper zone, while permanent gasification of charcoal takes in lower zone.

干燥，低温碳化和气体打击发生在上层，而永久气化木炭在较低的地带占地。
