摘要(Abstract):

根据陕北资源禀赋特点,粉煤中低温热解是适合陕北长焰煤特性的一种有效煤炭分质利用技术。研究表明:中低温热解产物焦粉的产率占70%左右,所蕴含的能量占80%左右。因此,从产率和能量的角度看,粉煤热解产物焦粉的综合利用应是煤炭中低温热解的重点。通过介绍6种焦粉利用方式,包括燃烧发电,气化,成浆,成型,高炉喷吹用煤,炭质吸附剂,提出了制定焦粉标准重要性,从而加速实现粉煤的清洁、高效、环保利用。
Based on the characteristics of Northern Shaanxi jet coal,find that low-medium temperature pyrolysis is the best utilization technology for jet coal.The studies show that,the coke powder makes up about 70 percent of low-medium temperature pyrolysis products,the power that the coke powder contains is about 80 percent.So the utilization of coke powder is the key of jet coal low-medium temperature pyrolysis research.Introduce six kinds of utilization methods,including power generation by combustion process,gasification,preparation of coal water slurry,briquette,spray-blow coal and adsorbent.Provide that the development of coke powder standard is an urgent affair for utilization of pulverized coal.
