ABSTRACT:
A combustion device for use with pressurized and zero pressure hot air balloons or other hot air appliances, which comprises in general, a coanda-type inlet nozzle, a diffuser, a flame-arrestor screen, and a fuel preheater means for supplying required fuel vapor at a desired pressure to the inlet nozzle. The combustion device may be used with any suitable fuel, but it is primarily applicable to propane. The combustion device is a fuel pressure driven-nozzle-mixer-diffuser-arrestor screen burner combustion device which generates a stream of heated air for the transfer of thermal energy to a load.
