Abstract
Abstract A flammable liquid waste burner is disclosed for firing in an open area in parallel, provisions being made for atomizing the liquid waste, with booster combustible gas supplied if needed, the flame being directed through pairs of spaced diverging cones in tandem, air being drawn in at the space between the cones and water being sprayed into the burning materials between the cones and at the exit of the second cone. The structure can be turned in accordance with the wind direction to avoid undesired deflection by the wind of the flame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
254 words
Apparatus for burning flammable liquid waste comprising a support, said support comprising a pivotally mounted frame for facing said housing and said cones in a selected substantially horizontal direction, a housing, said housing having means for controlling the delivery of air thereinto, a burner assembly carried by said housing, said burner assembly comprising members for supplying flammable liquid waste forwardly with respect to said housing and members for supplying supplemental fuel in close relation to the waste delivered from said first mentioned burner assembly members, a rear cone connected at its rear end to said housing and through which combustible materials from said burner assembly and air from said housing are delivered for burning therein, said rear cone and said housing being carried by said support, said rear cone being larger at its forward end, a front cone carried on said support extending forwardly from said rear cone in axial alignment therewith, said front cone at its rear end being spaced from the front end of said rear cone to provide an air entry space and being larger at its front end, a rear water spray ring contiguous to the front end of the rear cone and having members for directing water forwardly and inwardly into the space between said cones and into the flame therein, and a front water spray ring contiguous to the front end of the front cone and having members for directing water forwardly and inwardly beyond the front end of said front cone and into the flame advancing therebeyond.
Claim 2
Dependent Claim
254 words
Apparatus for burning flammable liquid waste comprising a support, said support comprising a pivotally mounted frame for facing said housing and said cones in a selected substantially horizontal direction, a housing, said housing having means for controlling the delivery of air thereinto, a burner assembly carried by said housing, said burner assembly comprising members for supplying flammable liquid waste forwardly with respect to said housing and members for supplying supplemental fuel in close relation to the waste delivered from said first mentioned burner assembly members, a rear cone connected at its rear end to said housing and through which combustible materials from said burner assembly and air from said housing are delivered for burning therein, said rear cone and said housing being carried by said support, said rear cone being larger at its forward end, a front cone carried on said support extending forwardly from said rear cone in axial alignment therewith, said front cone at its rear end being spaced from the front end of said rear cone to provide an air entry space and being larger at its front end, a rear water spray ring contiguous to the front end of the rear cone and having members for directing water forwardly and inwardly into the space between said cones and into the flame therein, and a front water spray ring contiguous to the front end of the front cone and having members for directing water forwardly and inwardly beyond the front end of said front cone and into the flame advancing therebeyond.
Claim 3
Dependent Claim
32 words
Apparatus for burning flammable liquid waste as defined in claim 1 which comprises a plurality of devices as defined in claim 1 mounted on said support and facing in the same direction.
Claim 4
Dependent Claim
26 words
Apparatus for burning flammable liquid waste as defined in claim 1 in which said second mentioned members include a connection to a supply of combustible gas.
Claim 5
Dependent Claim
35 words
Apparatus for burning flammable liquid waste as defined in claim 3 in which said second mentioned members are positioned to supply combustible gas into said rear cone in surrounding relation to the flammable liquid waste.
Claim 6
Dependent Claim
22 words
Apparatus for burning flammable liquid waste as defined in claim 1 in which the longitudinal axes of said cones are horizontally disposed.
Claim 7
Dependent Claim
25 words
Apparatus for burning flammable liquid waste as defined in claim 1 in which a pilot is provided for ignition at the space between said cones.
Claim 8
Dependent Claim
40 words
Apparatus for burning flammable liquid waste as defined in claim 1 in which said burner assembly members are relatively adjustable for varying the relationship of delivery of the supplemental fuel to the delivery of the liquid waste in spray form.
Claim 9
Dependent Claim
18 words
Apparatus for burning flammable liquid waste as defined in claim 1 in which said cones are of metal.
