For example, the present invention relates to a spark arrestor/trap that comprises a plurality of features that allows sparks/embers to be more effectively extinguished. The spark trap/arrestor of the present invention has at least two of vanes, conical devices and u-turns that allows for sufficient oxygen and a tortured path that is sufficiently long so as to effectively extinguish sparks and/or embers that enter the system. Alternatively, the system relates to a spark arrestor that comprises all of vanes, conical devices and u-turns that allows for sufficient oxygen and a tortured path that is sufficiently long so as to effectively extinguish sparks and/or embers that enter the system. In one embodiment, the various parts of the spark arrestor can be separated allowing for easy cleaning of the system. ## Claims ### Claim 1 A spark arrestor that comprises a) a conical device, b) one or more vanes, and c) at least one region wherein air is forced to u-turn, and d) an inner cylinder having a length and a diameter, wherein said conical device has a vertex, a curved surface, and a base, wherein a diameter of said base of the conical device is about 1.2 times the diameter of inner cylinder, said one or more vanes positioned on the curved surface of the conical device and so designed so that air that passes the one or more vanes is directed to go outside of the inner cylinder and when all of said air that is forced to u-turn encounters air that has just encountered said one or more vanes, all of said air that is forced to u-turn immediately u-turns again to pass into an inner diameter of said inner cylinder. ### Claim 2 (depends on 1) The spark arrestor of claim 1, further comprising an inlet port. ### Claim 3 (depends on 2) The spark arrestor of claim 2, wherein a volume of the inlet port is roughly equal in volume to the at least one region wherein air is forced to u-turn. ### Claim 4 (depends on 3) The spark arrestor of claim 3, wherein the one or more vanes are positioned so as to create a cyclone in the spark arrestor. ### Claim 5 (depends on 1) The spark arrestor of claim 1, wherein said inner cylinder is deposed in a position so as to create the at least one region wherein air is forced to u-turn. ### Claim 6 (depends on 5) The spark arrestor of claim 5, further comprising an inlet port. ### Claim 7 (depends on 6) The spark arrestor of claim 6, wherein a volume of the inlet port is roughly equal in volume to the at least one region wherein air is forced to u-turn. ### Claim 8 (depends on 7) The spark arrestor of claim 7, wherein the one or more vanes are designed so as to create a cyclone in the spark arrestor. ### Claim 9 (depends on 1) The spark arrestor of claim 1, wherein the vertex is positioned in a direction so that the vertex encounters air entering through an inlet port prior to the curved surface, and the curved surface encounters the air entering through the inlet port prior to the base, wherein the one or more vanes are positioned at one or more points where the base makes contact with the curved surface, the one or more vanes designed to direct air passing through the one or more vanes to the at least one region wherein air is forced to u-turn. ### Claim 10 (depends on 9) The spark arrestor of claim 9, wherein the one or more vanes are positioned so as to create a cyclone in the spark arrestor. ### Claim 11 (depends on 10) The spark arrestor of claim 10, further comprising an inlet port. ### Claim 12 (depends on 11) The spark arrestor of claim 11, wherein a volume of the inlet port is roughly equal in volume to the at least one region wherein air is forced to u-turn. ### Claim 13 (depends on 1) The spark arrestor of claim 1, wherein the spark arrestor further comprises one or more doors and/or one or more clamp joints. ### Claim 14 (depends on 1) The spark arrestor of claim 1, wherein the base of the conical device comprises indentations or protrusions. ### Claim 15 A spark arrestor that comprises a) a conical device, b) one or more vanes, c) at least one region wherein air that enters the spark arrestor is forced to u-turn, and d) an inner cylinder, wherein the conical device has a vertex, a base, and a curved surface, wherein the vertex is positioned in a direction so that the vertex encounters air entering through an inlet port prior to the curved surface, and the curved surface encounters the air entering through the inlet port prior to the base, wherein the one or more vanes are positioned on the curved surface of the conical device, the one or more vanes designed to direct air passing through the one or more vanes to the at least one region wherein air is forced to u-turn, the one or more vanes are positioned so as to create a cyclone in the spark arrestor, wherein the inner cylinder is deposed in a position so as to create the at least one region wherein air is forced to u-turn, and when all of said air that is forced to u-turn encounters air that has just encountered said one or more vanes, all of said air that is forced to u-turn immediately u-turns again to pass into an inner diameter of said inner cylinder and wherein a diameter of the inner cylinder is less than a diameter of the base of the conical device. ### Claim 16 A method of extinguishing embers and/or sparks by passing said embers and/or sparks through a spark arrestor, the spark arrestor comprising a) a conical device, b) one or more vanes, and c) at least one region wherein air that enters the spark arrestor is forced to u-turn, the method comprising at least passing said embers and/or sparks through the one or more vanes wherein said one or more vanes are positioned on a curved surface of the conical device said embers and/or sparks encountering said at least one region wherein air containing said embers and/or sparks is forced to u-turn, and after said air u-turns said air encounters air that has just encountered said one or more vanes, causing said air that has u-turned to immediately u-turn again to pass into an inner diameter of an inner cylinder positioned in said spark arrestor. ### Claim 17 (depends on 16) The method of claim 16, wherein the conical device has a vertex, a base, and the curved surface, wherein the vertex is positioned in a direction so that the vertex encounters air entering through an inlet port prior to the curved surface, and the curved surface encounters the air entering through the inlet port prior to the base, wherein the one or more vanes are designed to direct air passing through the one or more vanes to the at least one region wherein air is forced to u-turn. ### Claim 18 (depends on 17) The method of claim 17, further comprising an inner cylinder that is deposed in a position so as to create the at least one region wherein air is forced to u-turn. ### Claim 19 (depends on 18) The method of claim 18, wherein a diameter of the inner cylinder is less than a diameter of the base of the conical device. ### Claim 20 (depends on 19) The method of claim 19, wherein the diameter of the base of the conical device is between about 1.2 to 1.5 times larger than the diameter of the inner cylinder.
