devolatilization of coal meaning in English

低温炼焦

A kinetic characteristics algorithm of furnace combustion based on steady state is established , and a dynamic mathematical model of 450t / h cfb boiler made in china is developed in this paper . the model not only integrates the update theories and results of previous studies on the partial aspects , but also considers the main process in cfb boiler including flow , coal distribution , devolatilization of coal , char combustion , heat transfer and so on , and further improve the existing model of combustion kinetic characteristics
本文以国产450t h循环流化床电站锅炉为研究对象，在前人对循环流化床内部各种单独过程及模型化研究成果的基础上，深入考虑了燃煤粒径分布、流动、挥发分释放和燃烧、焦炭燃烧、传热等循环流化床内部进行的主要过程，进一步完善了炉内燃烧动态特性的数学模型。
