ABSTRACT:
A continuously-variable rate pulse combustion apparatus comprising a main burner, a primary burner operably connected to the main burner, main and primary fuel supply lines including valves for self-feeding a combustible gaseous mixture to the main and primary burners, respectively, main and primary air supply lines including valves for providing one-way flow of air to the main and primary burners, a combustion chamber for pulse combustion of the combustible gaseous mixture to provide combustion gases, and an exhaust mechanism for self-exhausting the combustion gases from the combustion chamber. An inlet air decoupler is provided for acoustically decoupling the main and primary air supply lines. The inlet air decoupler has a primary section in fluid communication with the primary air supply line and a main section in fluid communication with the main air supply line, a main inlet air tube for supplying combustion air to the main section, a primary inlet air tube for supplying combustion air to the primary section, and a main valve mechanism for controlling air flow into the main inlet air tube.
