Abstract

Hydrogen combustion is presented as a potential solution to cover the heat demand with renewable energies. However, current technologies do not allow the combustion of pure hydrogen and it must often be mixed with fossil fuels. Carbon dioxide (CO2) has proven to be useful for stabilizing hydrogen combustion, as has methane (CH4). Therefore, this research proposes the use of biogas as a stabilizer of pure hydrogen combustion. For this purpose, experimental tests were carried out, burning a lean biogas (BG 50% CH4) and a medium biogas (BG 60% CH4). Each biogas was burned in a commercial biogas burner with different percentages of hydrogen. Afterwards, the combustion temperature and the difference in temperatures obtained before and after combustion were analyzed. These parameters allow to study the dual effect between H2 and CO2. The results show that the balance between the percentage of CO2 and H2 is vital for efficient combustion. Therefore, this study significantly contributes to the advancement of sustainable combustion systems.
