Abstract
An electric control system for a pulse combustion device of the type which includes a combustion chamber mounted within a liquid vessel of a liquid heating apparatus, fuel and air inlet valves arranged to supply a mixture of fuel and air into the combustion chamber, a tailpipe connected at one end thereof to an exhaust port of the combustion chamber to take place therein resonant combustion of the mixture of fuel and air and immersed in an amount of liquid stored in the vessel, and an electrically operated air intake blower arranged to supply fresh air into the combustion chamber through the air inlet valve. The electric control system is designed to activate the air intake blower when a power source switch of the pulse combustion device has been first turn on and maintain activation of the blower for a first predetermined time after ignition of a mixture of fuel and air supplied into the combustion chamber through the inlet valves, to deactivate the blower upon lapse of the first predetermined time, and to activate the blower for a second predetermined time when a fresh mixture of fuel and air is supplied into the combustion chamber and ignited therein to control a temperature of the liquid in the vessel.
