This work presents the development of a burner for the utilization of low calorific value waste gas, as it arises in the
production of high purity hydrogen from biogas using an oxidative steam reforming process. Stable combustion of
different fuel gases with fluctuating gas composition over a wide operating range is assured by the application of
combustion in an inert porous medium (PIM) utilizing a kinematic flame stabilization mechanism. The development
of the PIM-burner bases on calculated effective flame speeds within PIM derived from a 1-D numerical model
including harsh operating conditions with preheating temperatures above 800 K and carbon dioxide concentration of
70 %-vol in the fuel gas. Experiments are conducted on a tailored test rig in order to validate numerical predictions
by comparison of calculated effective flame speeds to eff ective flame speeds derived from temperature
measurements in PIM.
