Abstract

The implementation of new emission standards under the Industrial Emissions Directive is helping to drive the introduction of new technologies by power producers. Producers in Poland using the common OP-140 type pulverized fuel fired boilers are looking for solutions to reduce NOx emission in flue gases. Selective Non-Catalytic Reduction (SNCR) technology is one of the de- NOx technologies tested for possible application in OP-140 type boilers. Optimization of the NOx emission reduction process in this technology consists of a selection of corresponding parameters of sprayed reagent in a boiler internal space. As part of project POIG.01.03.01 – 14 – 035/12 a simulation of thermal-flow conditions in a combustion chamber was carried out using Computational Fluid Dynamics (CFD) tools, among others simulation of thermal-fluid conditions in an OP-140 type boiler as well as the effect of operating parameters of the system that sprays out the reagent water solution and the influence of nozzle geometry on the spraying quality of this solution. This paper provides the results of aforementioned CFD simulations and experiments of SNCR technology operation for the considered optimal operating parameters (for selected levels of the OP-140 type boiler output) of this system.
