A feed valve is disclosed for self-feeding of air or fuel gas to a pulse combustion burner in response to oscillating burner pressures. The feed valve includes a housing having a plurality of flapper valves arranged to provide additive one-way flows into the valve housing and a combined single input flow into the burner.

Pulse combustion burner feed valve

The pulsed combustion gases of a primary burner having a low fuel input rate are combined with those of a main burner having a high fuel input rate to provide an integrated combustion process having a single pulse frequency and improved stability. The combustion gases of the primary burner are used to start the main burner by inducing the self-feeding of an air and fuel mixture into the main burner and igniting the mixture.
