ABSTRACT OF THE DISCLOSURE A method and apparatus is disclosed for monitoring and operating a pulse combustion heating generator comprising a Helmholtz resonator having a resonant chamber (13) arranged as a burning chamber, a pulse tube (14), one end thereof being connected to the burning chamber, the other end thereof being connected to a decoupler having an exhaust pipe (24), an inlet chamber (18) having an initiation blower (22), a valve (20) controlled by the pulse pressure of the burning chamber for regulating the connection (19) between the inlet chamber and the burning chamber, mens (15, 16) for injecting gaseous, floating or fluidized fuel in the burning chamber, and an ignition device (17, 17A) for the ignition of the fuel injected in the burning chamber, pressure variations in the heating generator generated during the operation of the heating generator being sensed. According to the invention the pressure variations in the inlet chamber (18) or a system communicating therewith are sensed, that the frequency of said pressure variations is compared with a predetermined frequency, and that said ignition device and initiation blower are turned off when there is a sufficient conformity between the frequency of the pressure variations and said predetermined frequency.
