英国苏格兰地区的一家工程公司使用一种新方法,能把煤碾细成极小的颗粒,因而可被用来作为一些燃料油的代替物。 其制作方法是把煤粉颗粒不断相互碰击破碎,最后形成只有几微米大小的微粒。它比现在发电厂用作燃料的煤粉颗粒小几十倍。煤粒度变小,燃烧效率就会提高,原来只用于烧油的锅炉稍经改动后可节省70%的燃料开支。 科学空们正在考虑将微煤用于蒸汽轮机和柴油机。但使用微煤也碰到一些问题,最主要的是设法减少装置的磨损。陶瓷燃烧室的使用可能使磨损大为减轻。
An engineering firm in the Scottish region of the United Kingdom used a new method of milling coal into tiny particles that could be used as a substitute for some fuel oils. Its production method is to pulverize pulverized coal particles constantly crushing, and finally the formation of only a few microns in size particles. It is several times smaller than pulverized coal particles used as fuel in power plants. Coal particle size smaller, the combustion efficiency will increase, the original only for the oil-fired boiler slightly modified to save 70% of fuel costs. Science is considering micro-coal for steam turbines and diesel engines. However, the use of micro-coal also encountered some problems, the most important thing is to try to reduce the wear and tear of the device. The use of ceramic combustor may greatly reduce wear and tear.
