前言目前,国内外正在探索新的煤炭燃烧方式,其中有的提出,要在蒸汽机车上进行“气化、半气化燃烧”的试验,即先将煤炭液化或气化,把固体的煤炭转为液体或气体燃料,使机车锅炉变“层燃”为“室燃”(以下称“气化燃烧”)。这样,既有利于环境保护,而且能弥补直接烧原煤所带来的经济效益低等问题。于是,英美一些厂家先后提出要用新技术(包括气化燃烧)改造蒸汽机车,使蒸汽机车在世界牵引动力中仍占一席之地。同时,铁道部“七五前进型蒸汽机车中改”科研计划中也安排了把锅炉“层燃”方 Preface At present, at home and abroad are exploring new ways of burning coal, some of them proposed steam locomotive to be “gasification, semi-gas combustion” test, that is, the first coal liquefaction or gasification, the solid coal turn For liquid or gaseous fuels, the locomotive boiler is “flared” to “flare” (hereinafter “gas flare”). In this way, it is not only conducive to environmental protection, but also can make up for the low economic benefits brought about by directly burning raw coal. As a result, some Anglo-American manufacturers have proposed to use new technologies (including gasification combustion) to transform steam locomotives, locomotive steam locomotive in the world is still a place. At the same time, the Ministry of Railways “seven five forward steam locomotive in the” scientific research plan also arranged the boiler “flammable” side
