Abstract
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.
