Abstract
A burner has a burner tube and a nozzle holder mounted in one end of the burner tube. An igniter is positioned within the nozzle holder and acts to ignite any of the multi-liquid fuels which may be used with the burner. A nozzle emits atomized liquid fuel under the venturi effect of the nozzle with compressed air being supplied to the nozzle. Primary air holes extend circumferentially around the nozzle holder to admit air radially which passes directly to the burner tube. Secondary air holes extend around the inside circumference of the burner tube on the secondary air injection plate and admit air axially to the burner tube.
Claims9
A burner system comprising a burner having an air aspirated nozzle, a compressor for supplying compressed air to said air aspirated nozzle, a fuel supply for supplying fuel to said air aspirated nozzle, a regulator for regulating the amount of fuel provided to said air aspirated nozzle, and a heat exchanger surrounding said burner, said heat exchanger having a plurality of flutes surrounding said burner, said flutes having an inside and outside surface area, a water supply to supply water under pressure to said heat exchanger, and to circulate said water through said heat exchanger, said inside area of said flutes being exposed to the heat produced by said burner and said outside area of said flutes being exposed to the water circulated through said heat exchanger.
