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.

Continuously-variable rate pulse combustion apparatus

A pulse combustion fired space heater is disclosed. The heater has an exterior cabinet enclosing an interior housing having a pulse combustion burner mounted therein. The burner includes a plurality of generally flat elements which cooperate with the interior housing to provide a tortuous path for air circulated through the chamber during heat transfer. The circulating air pressurizes the interior housing to enhance uniformity of heat transfer and suppress structural vibrations.

Pulse combustion space heater

A pulse combustion space heater and burner are disclosed. The heater has an exterior cabinet enclosing an interior housing having the burner mounted therein. The burner includes a plurality of generally flat elements which cooperate with the interior housing to provide a tortuous path for air circulated through the chamber during heat transfer. A labyrinthine air flow passageway lined with sound attenuating material is provided immediately upstream of the heater air discharge. The burner tailpipe comprises a weldment of two identical sheet metal pieces which cooperatively define a tailpipe conduit. A fuel gas inlet orifice is mounted in the wall of the mixer head to effect both regulation of the average flow rate and injection of the fuel to enhance its mixture with the air.
