It is very important to study the emission of pollutant from a coal combustion device, and it is a best way to adopt numerical simulation for such a study. By using a mathematical model with a post-processing method and based on combustion simulation, this paper calculates the SOx distribution in a power plant boiler furnace. For the formation of SOx, a conventional chemical reaction model is adopted, and according to the principles of reaction dynamics, a model for the SOx formation is also put forward. It is the first time for preceding the calculation and on-site testing an 800MW-unit boiler in China. The test and calculation results show that the model is reasonable, and such a study will be valuable as a reference to the boiler design and its clean operation.

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.
