Abstract
Abstract An anti-pollution heating system in which the flame from a gun type oil burner is fed into a cylindrical chamber somewhat larger in diameter than the outlet of the oil burner. The air feeding the flame is given a swirling motion by a set of stationary vanes in the air passage. The chamber curves inwardly to a reduced diameter outlet to momentarily retard the flow and cause all of the oil to become ignited. The products of combustion pass then into a large chamber where combustion is completed. The large chamber has perforated side walls to permit air to flow therein to provide sufficient oxygen to complete the combustion. A surrounding air chamber conducts air to the heated walls with some of the air flowing into the chamber and the remainder flowing to the air system of a home or other space to be heated. A lip underlies the jet of the oil burner to receive any oil dripping therefrom as the burner is turned off directing the oil into the combustion chamber where it is instantaneously atomized by the heated walls.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
An anti-pollution oil burning heating system comprising a gun type oil burner having an outlet tube, means in said tube for creating a swirling movement of the air passing therethrough, a primary combustion chamber secured to said tube to receive the products of combustion therefrom, said primary combustion chamber having a diameter greater than the diameter of said tube and having a reduced diameter outlet at the end thereof opposite said tube, a secondary combustion chamber secured to the outlet of said primary combustion chamber to receive products of combustion therefrom, said secondary combustion chamber having a diameter substantially greater than the diameter of said primary combustion chamber, a plurality of bores formed in the wall of said secondary combustion chamber to admit additional air thereto for completing the combustion of materials received from said primary combustion chamber, and means attached to said secondary combustion chamber for heating a fluid medium.
Claim 2
