EXPERIMENTAL RESEARCH AND INDUSTRIAL APPLICATION OF BURNER WITH BOAT-SHAPED FLAME STABILIZER ON LOW NO_x EMISSION

摘要

To the extent of the less emission of NO_x, we researched on a new type v multi-function burner, which has been widely applied in boiler in power plants of our country. Industrial practice and Experimental research demonstrate that, this kind of burner is not only helpful to the ignition and keeping stable combustion, but also favourable to control the NO_x formation in combustion process, which causes the reducing NO_x emission, because of the staging condition caused by its special flow field structure. In this paper we reported the NO_x emission from a utility boiler and the experimental results of the distribution of bulk temperature, compositions of combustion products, and NO_x concentration under two cases of burner with and without the boat-shaped flame stabilizer, and then compared and analyzed experimental results. Some corresponding conclusion was obtained as well.
