Unsteady ultra-lean combustion of methane and biogas in a porous burner – An experimental study

•Ultra lean flames in porous media respond to oscillations in fuel flow rate.•Flame motion is almost in phase with fuel flow fluctuations.•The amplitude of motion is larger for methane flames.•Long-term exposure to fluctuations results in flame destabilisation. The response of ultra-lean flames, sta...
