目前,我国城市居民中除部分居民实现了煤气化以外,绝大部分还是直接用煤燃烧。煤直接燃烧不但热效率低,而且排出大量的烟尘和大量废渣,不仅严重污染环境,而且浪费了大量的人力物力。因此,改变煤的燃烧方式,综合利用我国丰富的煤炭资源是一个很重要的问题。这里就贵州省如何合理利用煤炭资源,谈些粗浅的看法。一、贵州省化工用焦状况贵州省化学工业年耗能约140万吨标准煤,是全省用能大户之一,能耗量占全省总消费量的1/5。在化工生产中能源不但是燃料和动力,同时也是原料,在化工产品成本构成中占60-
At present, except for some residents in China's urban residents to achieve coal gasification, the vast majority of direct coal combustion. Direct combustion of coal not only low thermal efficiency, but also emit large amounts of dust and a large number of waste, not only seriously pollute the environment, but also a lot of waste of human and material resources. Therefore, changing the way of coal combustion, comprehensive utilization of China's abundant coal resources is a very important issue. Here on how to make rational use of coal resources in Guizhou Province, to talk about some superficial views. First, the state of Guizhou Province with coke chemical industry Guizhou Province, the annual consumption of about 1.4 million tons of standard coal chemical industry, is one of the province's energy consumption, energy consumption accounts for the province's total consumption of 1/5. In the production of chemical energy is not only fuel and power, but also raw materials, the cost of chemical products accounted for 60-
