An electric control system for a pulse combustion device of the type which includes a combustion chamber mounted within a liquid vessel of a liquid heating apparatus, fuel and air inlet valves arranged to supply a mixture of fuel and air into the combustion chamber, a tailpipe connected at one end thereof to an exhaust port of the combustion chamber to take place therein resonant combustion of the mixture of fuel and air and immersed in an amount of liquid stored in the vessel, and an electrically operated air intake blower arranged to supply fresh air into the combustion chamber through the air inlet valve. The electric control system is designed to activate the air intake blower when a power source switch of the pulse combustion device has been first turn on and maintain activation of the blower for a first predetermined time after ignition of a mixture of fuel and air supplied into the combustion chamber through the inlet valves, to deactivate the blower upon lapse of the first predetermined time, and to activate the blower for a second predetermined time when a fresh mixture of fuel and air is supplied into the combustion chamber and ignited therein to control a temperature of the liquid in the vessel.

Electric control apparatus for pulse combustion device

A pulse combustion apparatus comprises (i) a single air supply section with a single air blower and (ii) a plurality of combustion sections each communicating with the air supply section. The air supply section includes passages communicating with both the blower and the respective combustion sections for admitting air from the blower into the respective combustion sections. The air admitting passages are physically separated from each other for separating air from the blower into streams which are not able to join together anywhere.

Pulse combustion apparatus

A pulse combustion heating apparatus includes a open-top vessel assembled within a support frame to store an amount of liquid such as cooking oil to be heated, and a pulse combustion burner mounted to the vessel and having a combustion chamber secured at its inlet end to a side wall of the vessel and immersed in the liquid in the vessel and at least a pair of tailpipes each connected at their inner ends to an exhaust port of the combustion chamber in such a manner that the tailpipes are arranged symmetrically in the vessel and immersed in the liquid and being extended outwardly from the vessel. The vessel has a pair of parallel bottom walls inclined downwardly inwardly toward the center of the vessel, and a pair of cylindrical decouplers are housed in a pair of spaces just below the bottom walls of the vessel within the support frame and located in parallel along the bottom walls of the vessel. The decouplers are connected to each exhaust end of the tailpipes to stabilize pulse combustion in the combustion chamber.
