Abstract
Abstract A fluid fuel burner has a hollow casing within which is a coaxial hollow core member closed at one end and a distributor forming a mixing chamber in the core member which comprises a multiplicity of concentrically arranged axial passages for mixing oil and air. Steam is produced by heating water flowing through a coil in the casing forward of the core member heated by the combustion of the oil with the air and is introduced into the same chamber as the oil and air; it is mixed in the mixing chamber and in passing through the distributor with the oil and air to increase the flame temperature and volume, reduce the ratio of fuel consumption to heat output and burn the great majority of the waste gases.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
229 words
A fluid fuel burner including a hollow casing, a hollow gunbarrel-shaped cylindrical core member open at its forward end and closed at its rearward end supported centrally within said hollow casing, means to introduce air into said core member, means to introduce a fluid fuel into said core member, a coil supported within said casing forwardly of said core member to heat a fluid supplied thereto, first means to connect one end of said coil to fluid to be heated, second means to connect the other end of said coil to said core member to supply the heated fluid thereto, valve means to selectively control the flow of fluid to said coil through said first connecting means and distributor means disposed within said core member forwardly of the introduction of air, fluid fuel and heated fluid, said distributor means forming a chamber in the rear portion of said hollow core member into which the air, fluid fuel and heated fluid are introduced, thereby causing mixing of the heated fluid with the air and fluid fuel within the chamber and in passing through the distributor when said valve means allows flow of fluid to said coil, whereby the flame volume and temperature are maximized, the ratio of consumption of fluid fuel to the B.T.U. output of the burner is minimized and the great majority of the waste gases are burned.
