A pulse combustion apparatus comprising a metal pipe member, an exhaust chamber, and an insert member. The pipe member has two open ends and its inner diameter is uniform over its entire length. The first open end of the pipe member is closed, and the second open end thereof is connected to the exhaust chamber. The insert member is located within the pipe member such that it and the pipe member define a combustion chamber within the pipe member, close to the first end thereof, and also an exhaust passage connecting the combustion chamber to the exhaust chamber and having a cross section area smaller than that of the combustion chamber. The combustion chamber and the exhaust passage constitute a Helmholtz resonator which realizes pulse combustion of the fuel gas.
