Abstract: From aspects of generator design, configuration of switch valve, switch time, shape of burner, exhaust of NO_x and reaction mechanism etc., this paper has summarized the development of high temperature, especially with a strong focus on the status and development of HIAC in China. It pect of High Temperature Air Combustion technology. Research and application of fit to energy saving and reducing the exhaust of pollution of thermal equipment indushaust of NOx and reacti air combustion(HTAC) has expounded the pros HTAC have great benef try.
