Abstract

Abstract Apparatus to burn liquid fuels in a gaseous fuel burner, which includes preparatory apparatus for the atomization of liquid fuel oil preferably by a diluent gas, and the heating of the fuel droplets and diluent gas so as to completely vaporize the liquid fuel. If atomization is by other means, diluent gas is added prior to vaporization heating. The resulting oil vapor-diluent gas mixture then goes to a burner which utilizes the central orifice of a conventional gas burner. Primary air is induced into the burner tube due to the high velocity of jets of oil vapor-diluent gas. The diluent gas permits low vapor pressure of oil vapor and thus lower operating temperature. For the use of gaseous fuel, the same burner is utilized. The diluent gas can be preferably any noncombustible and non-oxygen containing gas.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 97 words
A method of burning a combustible liquid in an apparatus equipped with at least one orifice for normally during combustible gas, comprising the steps of: (a) atomizing said combustible liquid into very small droplets; (b) mixing said small droplets with a concurrently flowing selected diluent gas in advance of heating; (c) heating said mixture of liquid droplets plus diluent gas until said droplets vaporize, and a mixture of combustible vapor plus diluent gas is formed; and (d) flowing said mixture of combustible vapor plus diluent gas under pressure through said at least one orifice into a burner.
Claim 2
Independent Claim 97 words
A method of burning a combustible liquid in an apparatus equipped with at least one orifice for normally during combustible gas, comprising the steps of: (a) atomizing said combustible liquid into very small droplets; (b) mixing said small droplets with a concurrently flowing selected diluent gas in advance of heating; (c) heating said mixture of liquid droplets plus diluent gas until said droplets vaporize, and a mixture of combustible vapor plus diluent gas is formed; and (d) flowing said mixture of combustible vapor plus diluent gas under pressure through said at least one orifice into a burner.
Claim 3
Dependent Claim 39 words
The method as in claim 1 in which the ratio of diluent gas to liquid fuel is such that the partial pressure of the liquid vapor is such as to permit a reduced mixture temperature without condensing liquid vapor.
Claim 4
Dependent Claim 25 words
The method as in claim 1 in which the temperature of the liquid vapor-diluent gas mixture is below the ignition point of said liquid vapor.
Claim 5
Dependent Claim 16 words
The method as in claim 1 in which said diluent gas is a non-combustible, non-oxygen-containing gas.
Claim 6
Dependent Claim 38 words
The method as in claim 1 in which said diluent gas is a non-combustible gas having a low percentage of oxygen such that the mixture of said liquid vapor-diluent gas can be maintained below the lower explosive limit.
Claim 7
Dependent Claim 27 words
The method as in claim 1 in which said diluent gas comprises a combustible, gas of low heat value such as to be unburnable in conventional furnaces.
Claim 8
Dependent Claim 28 words
The method as in claim 1 in which the diluent gas is supplied under selected temperature and pressure to facilitate the atomization and vaporization of the liquid fuel.
