Abstract

Abstract A generally U-shaped, buoyant, self-propelled vessel floats partially submerged in a body of water and has a longitudinal channel portion with a front opening. The vessel has an open bottom portion beneath the longitudinal channel portion. As the vessel advances into a body of water, a band of water with the layer of combustible liquid floating thereon, enters the channel portion of the vessel. The rate at which the combustible liquid, as a layer, enters the channel portion of the vessel is dependent on the forward speed of the vessel and the speed is controlled so that substantially all of the layer of combustible liquid is removed by burning before the band of water psses under the rear portion of the vessel. As the vessel advances, the band of water with the layer of combustible liquid moves through a mixing chamber within the channel portion where a monolayer of cellular ceramic nodules are positioned on the top surface of the layer of combustible liquid. The layer of combustible liquid with the nodules floating thereon, moves rearwardly with the forward advance of the vessel into a combustion chamber where the layer of combustible liquid is ignited and burned. The nodules within the combustion chamber are recycled to the mixing chamber where they are again positioned as a monolayer on the upper surface of the layer of combustible liquid. Combustion air is provided for the combustion chamber and the combustion gases may be subjected to a secondary burning in the stack to remove the combustible materials in the combustion gases and provide a substantially smoke-free waste gas. Apparatus is provided to seal the combustion chamber and mixing chamber if the burning of the combustible liquid tends to spread beyond the receiver.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 134 words
Method for removing a layer of combustible liquid from the surface of a body of water comprising, advancing a buoyant vessel into a body of water having a layer of combustible liquid floating thereon, moving a Band of said body of water with said layer of combustible liquid floating thereon into a longitudinal channel portion within said vessel, positioning a layer of cellular ceramic nodules on the surface of said layer of combustible liquid floating on said band of water within said channel portion, igniting said layer of combustible liquid with said layer of cellular ceramic nodules floating thereon within the confines of said vessel, and removing said layer of combustible liquid with said layer of nodules positioned thereon from said band of water by burning said layer of combustible liquid within said vessel.
Claim 2
Dependent Claim 134 words
Method for removing a layer of combustible liquid from the surface of a body of water comprising, advancing a buoyant vessel into a body of water having a layer of combustible liquid floating thereon, moving a Band of said body of water with said layer of combustible liquid floating thereon into a longitudinal channel portion within said vessel, positioning a layer of cellular ceramic nodules on the surface of said layer of combustible liquid floating on said band of water within said channel portion, igniting said layer of combustible liquid with said layer of cellular ceramic nodules floating thereon within the confines of said vessel, and removing said layer of combustible liquid with said layer of nodules positioned thereon from said band of water by burning said layer of combustible liquid within said vessel.
Claim 3
Dependent Claim 53 words
A method for removing a layer of combustible liquid from the surface of a body of water as set forth in claim 1 which includes, maintaining said layer of combustible liquid on said band of water in a relatively quiescent state while moving said band rearwardly in said channel portion of said vessel.
Claim 4
Dependent Claim 45 words
A method for removing a layer of combustible liquid from the surface of a body of water as set forth in claim 1 which includes, removing said cellular ceramic nodules from said band of water after said layer of combustible liquid has been removed therefrom.
Claim 5
Dependent Claim 72 words
A method for removing a layer of combustible liquid from the surface of a body of water as set forth in claim 1 which includes, continuously advancing said vessel into said body of water having said layer of combustible liquid floating thereon at a preselected speed to remove said layer of combustible liquid from said band of water as said band of water moves rearwardly in said channel portion of said vessel.
Claim 6
Dependent Claim 60 words
A method for removing a layer of combustible liquid from the surface of a body of water as set forth in claim 4 which includes, continuously positioning a layer of nodules on said layer of combustible liquid at a forward location within said vessel channel portion as said band of water moves rearwardly in said channel portion of said vessel.
Claim 7
Dependent Claim 94 words
A method for removing a layer of combustible liquid from the surface of a body of water as set forth in claim 4 which includes, removing said cellular ceramic nodules from said band of water adjacent the rear portion of said vessel channel portion after said layer of combustible liquid has been removed therefrom, and conveying said nodules removed from said band of water to said forward location of said channel portion for positioning on said layer of combustible liquid floating on said band and moving rearwardly in said channel portion of said vessel.
Claim 8
Dependent Claim 137 words
Apparatus for removing a layer of combustible liquid from a body of water comprising, a self-propelled vessel having a pair of spaced side portions with a longitudinal channel portion therebetween, said vessel having an open bottom portion beneath said channel portion and a front opening for said channel portion so that a band of water with a layer of combustible liquid floating thereon moves rearwardly in said channel portion as said vessel advances in said body of water, means to position a layer of cellular ceramic nodules on the layer of combustible liquid floating on said band of water at a forward location in said channel portion, and means to burn said layer of combustible liquid with said layer of cellular ceramic nodules positioned thereon at a location adjacent the rear portion of said vessel channel portion.
Claim 9
Dependent Claim 137 words
Apparatus for removing a layer of combustible liquid from a body of water comprising, a self-propelled vessel having a pair of spaced side portions with a longitudinal channel portion therebetween, said vessel having an open bottom portion beneath said channel portion and a front opening for said channel portion so that a band of water with a layer of combustible liquid floating thereon moves rearwardly in said channel portion as said vessel advances in said body of water, means to position a layer of cellular ceramic nodules on the layer of combustible liquid floating on said band of water at a forward location in said channel portion, and means to burn said layer of combustible liquid with said layer of cellular ceramic nodules positioned thereon at a location adjacent the rear portion of said vessel channel portion.
Claim 10
Dependent Claim 55 words
Apparatus for removing a layer of combustible liquid from a body of water as set forth in claim 7 which includes, an enclosure for the rear portion of said vessel channel portion forming a combustion chamber within in which said layer of combustible liquid with said layer of cellular ceramic nodules floating thereon is burned.
Claim 11
Dependent Claim 39 words
Apparatus for removing a layer of combustible liquid from a body of water as set forth in claim 8 which includes, means to remove said cellular ceramic nodules in said layer adjacent the rear portion of said combustion chamber.
Claim 12
Dependent Claim 47 words
Apparatus for removing a lAyer of combustible liquid from a body of water as set forth in claim 9 which includes, means to convey said cellular ceramic nodules removed from said layer adjacent said combustion chamber rear portion to a forward portion in said vessel channel portion.
