随着工农业和交通运输业的迅速发展,人类社会对矿物燃料的需求越来越大。石油既是一种比较清洁而又使用便利的通用燃料,又是可贵的化工原料,其需求量增长尤为迅速。石油资源最终枯竭的前景是意料中的事。矿物燃料中得天独厚,储量最大的是煤。仅以我国而论,现已探明的煤的天然储量有几千亿吨,按现在的年产量估计,可供开采一千多年。但是,煤既不适用于原有的烧油锅炉、各种动力装置和输送系统,燃烧后排放的废气和粉尘又
With the rapid development of industry, agriculture and transportation, the human society has an increasing demand for fossil fuels. As a relatively clean and easy-to-use general fuel, but also a valuable chemical raw material, the demand for oil is increasing rapidly. The prospect of a final depletion of oil resources is a surprise. Blessed with fossil fuels, the largest reserves are coal. For our own purposes alone, the reserves of present-day proven coal are hundreds of billions of tons of natural reserves, estimated at current annual production levels, for more than a thousand years. However, coal is neither suitable for the original oil-fired boiler, various power plant and delivery system, the exhaust gas and dust discharged after combustion
