The invention relates to a method and a device for monitoring and controlling 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, a decoupler (23) connected to the other end of the pulse tube and being provided with an exhaust pipe (24), an inlet chamber (18) having an initiation blower (22), a valve (20) controlled by pulse pressure in the burning chamber for controlling the connection between said inlet chamber and said burning chamber, means (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 the burning chamber. Pressure variations in the heating generator generated during operation thereof are sensed by a sensor (25), the output thereof being supplied to a comparator to have the frequency of the pressure variations compared with a predetermined frequency. When there is a sufficient conformity between the frequency of the pressure variations and said predetermined frequency a device is actuated for the shutdown of said ignition device and said initiation blower. |
