英文摘要：

According to the production mechanism and characteristic of NOx, the technologies of NOx inhibiting and removing in the process of coal combustion were classified into three kinds： nitrogen-free combustion, low NOx combustion and de-nitrification of flue gas. The present situation and characteristics of these ordinary de-nitrification technologies were reviewed and analyzed in this paper, and some new de-nitrification technologies developed in recent years were also described. The costs of operation in the technology of de-nitrification of flue gas and nitrogen-free combustion were higher, and the de-nitrification rate of the current low NOx combustion was lower. Thus new technologies of NOx inhibiting in the combustion should be developed to adapt to the current situation in China. A new method of controlling NOx generation in the process of sintering was proposed, which is based on the principle of coupling and decoupling combustion of coal by minimizing and controlling NOx contamination from its very beginning of generation.
