  • High efficiency conveyor oven
    Patent number: 6655373
    Abstract: A conveyor oven is heated by inshot burners, which eliminate blowers, ducts, and motors heretofore required to supply a force draft of combustion air to the burners. Apertures in front of the inshot burners have a diameter that regulates the amount of combustion air that is delivered to the burners. The only blower in the oven is the one required to circulate and recirculate hot air within the oven which produces three pressure zones that causes an induced draft of combustion air for the inshot burner. A modulating valve adjusts the flow of gas to the inshot burners.
