在能源的生产和消费结构中,我国历来是以煤为主的。如何合理地、有效地利用煤炭燃料,是摆在我们面前的重大研究课题。在技术先进的资本主义国家,较高发热值煤气的气化技术,在经济上还不能推广使用,我国在这方面还处于开始试验研究阶段。煤的液化、煤油混合燃料、煤水浆等,还没有或刚刚提到日程上来,到工业性使用,还有一段漫长的道路。煤的层状燃烧法在热工上技术上有不少不可克服的缺点。因 In the energy production and consumption structure, China has always been based on coal. How to use coal fuel reasonably and effectively is a major research topic before us. In technologically advanced capitalist countries, the gasification technology of a higher calorific value gas can not be economically promoted, and our country is still in the experimental and research stage in this respect. Coal liquefaction, kerosene blends, coal-water slurry, etc., have not yet or just mentioned the agenda, to the industrial use, there is still a long way. Layered combustion of coal in the thermal technology there are many unskilled shortcomings. because
