To improve energy savings and emission reduction in industrial heating furnaces, this study investigated the impact of various molar fractions hydrogen on natural gas combustion compared results Non-Premixed Combustion Model with Eddy Dissipation Model. Initially, an furnace was experimentally, these were used as boundary conditions for CFD simulations. The diffusion flame characteristics simulated using both non-premixed model indicated that provided simulations more consistent experimental data, within acceptable error margins, thus validating accuracy numerical Additionally, to analyze doping performance heater, four mixtures varying contents (15% H2, 30% 45% 60% H2) studied while maintaining constant fuel inlet temperature flow rate. demonstrate accurately simulates complex flue chemical reactions during combustion. Moreover, hydrogen-doped significantly reduces CO CO2 emissions pure Specifically, at content, levels decrease by 70% 37.5%, respectively, NO increase proportionally; concentration chamber rises 155%.
