一、引言型煤是指把煤末压制成各种特殊形状,具有一定强度的煤团。在国外,层燃工业炉普遍燃烧型煤。例如:1980年西德生产褐煤1.4亿吨,其中竞有一半是成型燃烧的,工业锅炉百分之八十使用型煤。烧工业型煤比统煤可大大提高热效率,并且减轻了对环境的污染。1982年11月到12月在北京力学研究所的开封锅炉厂生产的RZL-250-10/150型热水供暖锅炉上试烧中国矿业学院研究生部研制的工业型煤。在型煤与统煤的对比性试验中,表明热效率提高11.77％,节煤可达17.2％,而烟尘排放量减少了一半。使用工业型煤,设备不需要改造,具备投资
I. Introduction Briquette refers to the coal pressed into a variety of special shapes, with a certain intensity of the coal group. Abroad, stoker burning industrial coal combustion generally. For example, West Germany produced 140 million tons of lignite in 1980, half of which was combustion by combustion and 80% by industrial boilers. Burning industrial briquette can greatly improve the thermal efficiency of coal, and reduce the pollution of the environment. November 1982 to December at the Beijing Institute of Mechanics Kaifeng Boiler Factory RZL-250-10 / 150 hot water heating boiler trial burned China Institute of Mines Graduate Institute of industrial briquette. In the comparative tests of briquette and coal, it shows that the thermal efficiency is increased by 11.77%, the coal saving is up to 17.2% and the soot emission is reduced by half. Use of industrial coal, equipment does not need to transform, with investment
