Abstract
A pulse burner includes: a combustion chamber provided in a liquid vat capable of storing liquid; a tail pipe that is connected to the combustion chamber and has a heat exchanging portion located in the liquid vat and bent in a predetermined shape; and a mixing chamber which communicates with the combustion chamber and to which fuel gas and combustion air is allowed to be supplied. When mixed gas including the fuel gas and the combustion gas is exploded and combusted, the combustion exhaust gas is exhausted through the tail pipe to allow heat exchange with the liquid, and the mixed gas is inhaled from the mixing chamber into the combustion chamber. At least the heat exchanging portion of the tail pipe is bent on a substantially horizontal plane.
