一、概况我国以煤为主的能源结构在一个相当长的时期内,不会发生根本性的变化。目前,我国煤的利用方式主要是直接燃烧。这不仅能源利用率低,而且还带来严重的环境污染。实践表明,将煤炭转变为更有利的能源和产品形式的各项技术中,煤的气化是受到优先考虑的一种重要的加工方法。在发展城市煤气和工业燃料气、化工合成原料气以及为联合循环发电提供洁净的煤气等方面,煤的气化技术都起着关键性的作用。煤的气化方法很多,本文将重点评述沸腾煤气化技术。它是一种煤种适应性较强,煤 I. Overview China’s coal-dominated energy structure in a fairly long period of time, there will be no fundamental change. At present, the utilization of coal in our country is mainly direct combustion. This not only low energy utilization, but also bring about serious environmental pollution. Practice shows that coal gasification is an important processing priority given the technologies that transform coal into more favorable forms of energy and products. Coal gasification technology plays a key role in the development of city gas and industrial fuel gas, chemical synthesis feed gas, and clean coal gas for combined cycle power generation. Coal gasification methods are many, this article will focus on boiling coal gasification technology. It is a kind of coal adaptability, coal
