Using CFD modeling and thermal calculations to increase operation efficiency water heating boiler unit
https://doi.org/10.15518/isjaee.2023.11.047-055
Abstract
The article discusses a simplified approach to modeling the processes occurring in the combustion chamber of a hot water boiler with an inclined-pushing grate. Numerical modeling of the water-heating boiler of the Kovrov plant KVm-4D was carried out, on the basis of which recommendations for improving its design were proposed, and the results of numerical modeling of temperature fields and concentrations of combustion products were clearly presented. Thermal calculations were performed under various operating modes and the design of the boiler combustion chamber and the effectiveness of the proposed changes was shown. A detailed approach to performing thermal calculations of a boiler unit with flue gas recirculation has been developed.
