ABSTRACT:
In a combustion heater, a fuel feed unit supplies a fuel uniformly into a burner so as to prevent incomplete combustion in the burner. When a vaporization member is provided in the burner, the fuel feed unit supplies the fuel uniformly all over the surface of the vaporization member so that the incomplete combustion in the burner is also prevented. In addition or alternatively, the fuel feed unit includes a fuel feed pipe and a valve unit which is provided at a tip portion of the fuel feed pipe, so as to prevent emissions of an unburned fuel. In addition or alternatively, a temperature of the fuel supplied to the burner is monitored, and an operation of the fuel feed unit or an air feed unit for supplying combustion air to the burner is controlled based on the monitored fuel temperature so as to provide a desirable air-fuel mixture for preventing incomplete combustion in the burner. An amount of the fuel supplied to the burner or an oxygen concentration in an exhaust gas after combustion in the burner may be monitored instead of the fuel temperature.
