Control Technology Research on Low-NOx Combustion System in Large-Scale Coal-Fired Power Plants

The mechanism of NOx formation in coal combustion, NOx control methods and key DeNOx technologies is to be introduced. Denitrification is very significant for saving energy and carbon sources. By analysis of NOx production mechanism, the principles of controlling NOx production and lowering emission of NOx by classified combustion are described. Combined with actual operation, low-NOx combustion rehabilitation programs and relevant test to be done is to be proposed. The actual operation of the unit achieved good results after the transformation, provide a reference for similar units.
