CFD PARAMETRIC DESIGN SIMULATION OF COMBUSTION SEQUENCE IN GAS HEAT ELEMENT

Gas Engineering

Through an effective and reasonable design of the heat element structure, the combustion impact of natural gas-air mixed combustion is optimized, resulting in a reduction of atmospheric pollutants and energy savings and emission reductions. This article begins with a geometric model of the heat element and then utilizes Computational Fluid Dynamics (CFD) technology to numerically simulate the heat element's combustion sequence, which results in the heat element's combustion sequence after structural optimization. The blower guide vanes have a negligible guiding impact on the airflow, but the mounting body of the guide vanes has a substantial back pressure effect, which limits the primary air volume and prolongs the combustion history in the flame's center area; The temperature field is well spread, and the combustion is well dispersed; the CH4 and CO2 in the furnace chamber are essentially burnt away, and the NO concentration in the furnace chamber is around 800 ppm, which fulfills the emission requirement and has a good combustion effect. This article serves as a guide for future research on heat element structure.
