摘要:
A flame tube for a liquid fuel burner is disclosed. The liquid fuel burner includes a fuel atomizer directing atomized fuel into the flame tube and an igniter disposed within the flame tube to ignite the atomized fuel. The flame tube comprises an outer wall and an inner wall disposed about the outer wall to define an air passage therebetween. At a discharge end of the flame tube, the outer and inner walls are conjoined to form an annular surface, the annular surface being perforated. Preferably, the annular surface is perforated in an evenly distributed pattern.

摘要:
An improved tray ration heating system includes a reservoir. A heat exchanger transfers heat to the reservoir. A firebox at one end of the reservoir has an opening to receive a burner flame tube. The firebox delivers heated gases from the burner flame tube along the underside of the reservoir to an opposite end of the reservoir. A main channel along the reservoir includes baffles which produce a tortuous path and introduce turbulence to, the hot gases. First and second channels adjacent to the main channel redirect hot gases exiting the main channel, and third and fourth channels direct hot gases exiting the first and second channels towards the opposite end of the reservoir. An exhaust channel extends along a vertical wall of the reservoir to an exhaust opening. The exhaust channel has baffles for displacing hot gases across the vertical wall. An insulated outer liner supports the reservoir and heat exchanger.
