| Zusammenfassung: | Title screen In this paper, we present the results of a numerical investigation into the combustion process in a boiler furnace chamber with swirl burners using design coal (non-coking coal) and substitute coal (coking coal). The paper describes the development of a three-dimensional combustion model for coal burning in a boiler furnace chamber. The utility boiler operates on high-ash non-coking coal with an ash content of 41.94%. Due to the high ash content in the design coal, most of it is released into the atmosphere, which negatively affects the environment and the surrounding area. We suggest that this coal by a different coal with a lower ash content. It was found that during the combustion of substitute coal at the level of burner, the temperature in the entire cross section increases by 200?K, due to more intense fuel burnout at the outer boundary of the burner torches. It is found that the substitute coal may be burned in the boiler furnace chamber and can provide reliable operation if the swirl burner angle is set at 50° for the secondary air and at 45° for the fuel-air mixture.
