Abstract
Hydrogen gas plays a crucial role as a fuel in renewable energy projects. Water electrolysis is used when hydrogen gas is produced through renewable and green methods. This method, however, remains open to development due to its high cost. Oxygen is also produced along with hydrogen gas during water electrolysis. This study proposes that, to reduce the cost of hydrogen production, the oxygen generated during production should be directly burned in a nearby burner without any storage. For this purpose, hydrogen gas was added to natural gas at volumetric rates of 10%, 20%, and 30% in a burner maintained at a constant thermal power of 33 kW. Furthermore, the oxygen-enriched combustion method was applied to all natural gas/hydrogen mixtures. The results show that hydrogen addition increases the combustion chamber exit temperature. Furthermore, during the oxygen enrichment process, both flame temperature and boiler exit temperature increased up to 31% O2. After this O2 level, the temperature values decreased. Furthermore, NOX emissions at the combustion chamber exit showed a linear change with temperature data. Especially at high Hydrogen ratios, NOX emissions of 28.5% O2 and above 20 ppm were detected.
