The significance of hydrogen as a fuel has grown in recent years. The most common method used in hydrogen production is the steam methane reformer (SMR). The steam methane reforming reaction in the industrial sector is a verified, simple, cost-effective, and promising method of producing hydrogen-rich syngas. However, there are various limitations related to storage and transport. In this study, hydrogen production by SMR and utilization in the combustion chamber are numerically investigated. The syngas produced in the SMR reactor were passed through a separator to obtain a mixture of hydrogen and slip methane. This mixture was fed to the combustion chamber to lower pollutants and fuel consumption. Hydrogen-enriched combustion using the SMR system was performed with different SMR inlet velocities and H2O/CH4 ratios. As a result of the study, the hydrogen production, combustion chamber temperature, specific fuel consumption, and CO2 emissions of the SMR reactor were determined. As a result of the findings, specific fuel consumption and CO2 emissions for the combined SMR-combustion process are reduced by approximately 85% and 7%, respectively. Hydrogen production in the SMR reactor increases proportionally with rising reformer inlet velocity. Approximately 40% hydrogen production increase was observed between the highest and the lowest reformer inlet velocity. Hydrogen production in the SMR reactor increases with increasing velocity.
