煤炭是我国现阶段的主要能源,82年能源构成中煤炭占71.4％。目前大部份用于直接燃烧,由于煤质差,设备陈旧,热能利用效率低,浪费大,对环境的污染也很严重。发展煤炭加工利用(煤的转化)技术,提高加工深度,可以收到节约能源、改善环境保护,提高经济价值的综合效果。国外一些工业先进的国家,对煤炭加工利用都很重视。例如日本虽然能源结构以石油为主,82年煤炭只占能源总量的16.7％,而且大部份来自国外,但政府部门和产业界人士却把煤炭视为未来的可靠能源之一,十分注重加工利用技术的研究。他们集中较多的科研力量,在改革燃烧工艺、增加商品的规格品种、寻求把煤炭转化成可以与石油媲美的
Coal is the main energy source in China at this stage. Coal accounted for 71.4% of the energy composition in the year 82. At present, most of them are used for direct combustion. Due to the poor quality of coal, outdated equipment, low efficiency of heat energy use, large waste, and serious environmental pollution. The development of coal processing and utilization technology (coal conversion) technology and the improvement of processing depth can receive comprehensive effects of energy conservation, improvement of environmental protection and improvement of economic value. Some advanced countries in the world have paid great attention to coal processing and utilization. For example, although Japan’s energy structure is dominated by oil, coal accounted for only 16.7% of total energy in 82 years, and most of it comes from abroad, but government and industry people regard coal as one of the future reliable sources of energy. Processing technology research. They focused more on scientific research, reformed the burning process, increased the variety of commodity specifications, and sought to convert coal into something comparable to oil.
