油煤混合燃料(简称COM)就是把一定细度的煤粉和重油均匀混乱的浆状体,它是目前石油短缺的情况下,节约用油,以煤代油的有效措施。我们只要对电站燃油锅炉和燃油工业炉作部分改动,就可利用原来的燃油系统改烧油煤混合燃料,当煤粉浓度为45～50％时可节油约为30％,並可进一步发展到使用油、煤、水混合燃料,直到目前各国正在努力研究的水煤浆燃料,以达到完全以煤代油的目的。油煤混合燃料的制备,输送和燃烧是一 Oil-coal mixed fuel (COM) is a slurry with a certain degree of fineness and uniform disruption of pulverized coal. It is an effective measure to save oil and replace oil with coal under the current shortage of oil. As long as we make some changes to the power station boiler and the fuel furnace, we can use the original fuel system to convert the coal-fired fuel mixture, which can save 30% fuel when the pulverized coal concentration is 45% -50%, and can be further developed Until the use of oil, coal and water fuel mixture, until now countries are working hard to study the coal-water slurry fuel, in order to achieve the purpose of completely replacing coal with oil. The preparation, transportation and combustion of oil-coal mixed fuel are one
