熔融床煤气化技术研究现状

Research status of melting gasifying

从中国能源和环境的角度出发,分析了煤气化的重要性,重点介绍了铁浴、盐浴及渣浴气化工艺的主要原理及技术。早期的熔融床气化技术由于存在熔渣析铁和熔盐再生等问题,没有的得到很好的推广发展,但是随着近年来熔融还原炼铁技术和熔盐气化-燃料电池联合技术的发展,熔融床气化必将得到人们的重新重视。

From the standpoint of China＇s energy and environment, the importance of coal gasification was analyzed. The principles and technologies of coal gasification in liquid iron bath and coal gasification by motel salt and coal gasification in molten slag were mainly intredueed. Melting gasifying was not developed due to ferrite euteetoid and salt regeneration. In recent yeas, with the development of melting reduction iron-making technique and the combined power generation system of coal gasification by molten salt and fuel battery, melting gasifying will receive renewed attention.
