Reduction harmful emissions at the pulverized fuel combustion in the furnace chamber
Original language description
The basic characteristics of heat and mass transfer processes in the furnace chamber of the BKZ-75 boiler of the Shakhtinskaya thermal power plant (Kazakhstan) using numerical methods were studied during a forced partial stop of the supply of coal dust through burners. Two methods were studied: 1– a direct-flow method of supplying air mixtures: two direct-flow burners are working and two are in emergency mode; 2 – vortex method of supplying air mixtures: two vortex burners with a swirl angle of the air mixture flow and their inclination to the center of symmetry of the boiler by 30 degrees and two are in emergency mode. The numerical experiments allowed to obtain the temperature fields and concentration of carbon monoxides CO, nitrogen dioxide NO2 throughout the entire volume of the combustion chamber and conduct a comparative analysis for the two investigated emergency mode. It can be concluded that in the case of a forced partial stop of the supply of coal dust, the use of the vortex method of supplying air mixtures improves heat and mass transfer processes and allows minimizing emissions of harmful substances.
