This study demonstrates the potential of biogenic synthesis gases as a renewable alternative to natural gas for industrial process heat. The process chain integrates allothermal steam gasification using the Heatpipe Reformer, single-stage fixed-bed methanation, and direct combustion in a FLOX burner. Laboratory-scale experiments show that partial methanation increases the calorific value of the gas, doubling it, and reduces tar content to below 1 g/Nm3, facilitating cleaner gas utilization. FLOX burner tests with synthetic gas mixtures reveal that an increase in hydrogen content leads to higher NOx emissions, whereas a higher steam content mitigates this effectOver a continuous 72-hour operation, the burner consistently performed with syngas, maintaining stable operation. Emission measurements confirm that the system complies with regulatory limits, identifying biomass nitrogen as the primary source of NOx emissions. These results demonstrate that industrial heating processes can integrate biogenic synthesis gases without the need for an external hydrogen supply for gas conditioning.
