Features of Formation and Suppression of Sulfur Oxide Emissions During Burning Fuels in an Oxygen Medium With CO2 Recirculation

  • Published:
Power Technology and Engineering Aims and scope

The main mechanisms of formation and suppression of sulfur oxides during combustion of solid fuels in a CFB and the main regime factors affecting the concentration of sulfur oxides during air combustion are considered. Features are demonstrated for mechanisms of formation and suppression of sulfur oxide emissions during combustion with oxygen, which are largely associated with a high partial pressure of carbon dioxide mixed with oxygen. Comparative analysis of the effect of entrapping SOx and regime factors during combustion of oxygen and CO2 in air and the environment is performed. The most preferred mathematical models for calculating SOx emissions are given and the calculated results are compared with experimental data. Directions and approaches for further research are indicated, primarily in the direction of modeling under conditions of combined combustion of coal and biomass. It is shown that it is important to conduct comprehensive studies of processes for formation and suppression of harmful emissions from combined combustion of coal and various types of biomass, especially when burning in an oxygen atmosphere with CO2 recirculation.
