Study on quick pretreatment of coal heating effects on caking property

Abstract：By analysis of primary energy resources and consumption structure in China and the world, the efficient technology means of energy sustainable development, which is coal rapid heating, was obtained.the research development course of coal flash heat craft was reviewed.In past research, coal heating to soften rapidly melting temperature (400 ~ 500 ℃) can greatly enhance their caking property.Through datailedly narrated and commented super coking technology SCOPE21, it showed that the rapid heating preconditioning coal, coking with a low temperature, can not guarantee the quality of coke to reduce the premise, and it can increase the slightly caking and non-caking coal to fifty percent.Compared with existing coking process, production efficiency increase 1.4 times and energy saving about twenty percent.
