An improved nozzle spray type burner including a combustion chamber, a housing having an exhaust passage coupled to the combustion chamber, a fan mounted in the housing for directing air through the exhaust passage to the combustion chamber and a fuel spray nozzle in the exhaust passage for spraying fuel into the flow of air in the exhaust passage. The improvement includes a first mechanism associated with the fan to control the flow rate of air in the exhaust passage, and a second mechanism associated with the nozzle for controlling the amount of fuel sprayed from the nozzle. The first and second mechanisms are arranged to cooperate to control the degree of combustion of the fuel with the air in the combustion chamber.

Combustion control device for nozzle spray type burner

An infrared heater includes a combustion chamber having a radiator with a surface arranged to direct radiant heat in a forward heating direction. A fan has an outlet opening which is located to direct a flow of air above the radiating surface, thereby deflecting convective air heated by the combustion chamber in the forward direction. The fan is mounted above and on the rear side of the chamber so that it is out of the influence of radiant and convective heat developed by the chamber. A motor which drives the fan is mounted at one end of the fan so that the motor is also not affected by the radiant and convective heat.
