COMBUSTION BURNER
A combustion burner device that includes a rotor chamber with a rotary element rotatably mounted therein. The rotor chamber has a cylindrical sidewall with an inlet port in communication with a source of pressurized gas and an outlet port in communication with a combustion chamber. The rotary element has at least two interrupters forming cavities therebetween within the rotor chamber. The cavities are configured for receiving pressurized gas from the chamber's inlet port and transferring the pressurized gas to the chamber's outlet port. The rotation of the rotary element is in response to and by way of reaction to the issuance of gas under pressure through the inlet port.
1 . A burner for gaseous fuel supplied under pressure, said burner comprising:
a cylindrical rotor chamber including a sidewall with an inner surface and an outer surface, an inlet port and an outlet port, said inlet port being in communication with a source of gas under pressure;
a rotary element including at least two radially extending, circumferentially spaced interrupters, said rotary element being rotatably mounted within said rotor chamber and having a diameter substantially equal to a diameter of the inner surface of said rotor chamber; and
a combustion chamber including an inlet port in communication with said rotor chamber outlet port and an outlet port, said combustion chamber being suitable for containing combustion of said gas therein.
2 . The burner of claim 1 further comprising a tube extending between the outlet port of said rotor chamber and the inlet port of said combustion chamber to place the rotor chamber and combustion chamber in communication with one another.
3 . The burner of claim 1 wherein rotation of said rotary element creates a pulsating flow of gas into said combustion chamber.
4 . The burner of claim 1 wherein combustion chamber includes an inlet for inducting air with said gas.
5 . The burner of claim 1 further comprising an air inlet upstream of and in communication with said rotor chamber inlet port for creating a mixture having a desired air-gas ratio.
6 . The burner of claim 5 wherein said rotary element further mixes said air and gas for enhancing the completeness of combustion.
7 . The burner of claim 5 wherein said rotary element creates a disruptive condition within said air-gas mixture leading to an increased turbulence in flow.
8 . The burner of claim 1 wherein a flow of the gas entering said rotor chamber causes the rotary element to turn.
9 . The burner of claim 8 wherein the rotary element turns between about 240 and 360 rounds per minute depending upon the amount of gas flowing into said rotor chamber.
10 . The burner of claim 1 wherein combustion occurs within said combustion chamber when one of said interrupters is covering said rotor chamber outlet port.
11 . The burner of claim 1 wherein said rotary element interrupters each have an end face and an indention formed into said end face.
12 . The burner of claim 11 wherein said indentions assist in initiating rotary element rotation when gas flow is commenced.
13 . The burner of claim 11 wherein said indentions assist in preventing said rotary element from becoming static once gas flow has commenced.
14 . The burner of claim 1 wherein said rotor chamber and combustion chamber are each comprised of a cylindrical sidewall and two end caps.
15 . The burner of claim 1 wherein said rotary element interrupters each have an outer radius substantially equal to a radius of the inner surface of said rotor chamber.
16 . The burner of claim 1 wherein said rotor chamber inlet port is in communication with a flow control valve for controlling the amount of gas flowing into said rotor chamber.
17 . The burner of claim 1 wherein said burner is configured for use in connection with at least one of a furnace, hot water heater, boiler, gas stove, gas oven, clothes dryer and gas fireplace.
18 . The burner of claim 1 wherein said gas is selected from the group consisting of natural gas, propane, methane, butane and combinations thereof.
19 . A pulse combustion burner comprising:
a rotor chamber including a cylindrical sidewall with inner and outer surfaces, first and second end caps, an inlet port in communication with a source of pressurized gas and an outlet port, said rotor chamber configured for housing a rotor therein;
a rotor rotatably mounted within said rotor chamber, said rotor including at least two radially extending, circumferentially spaced interrupters, wherein said interrupters each have an outer radius substantially equal to a radius of the inner surface of said rotor chamber;
a combustion chamber including a sidewall, first and second end caps, an inlet port and an outlet port; and
a tube extending between said rotor chamber outlet port and combustion chamber inlet port placing the rotor chamber in communication with the combustion chamber.
20 . The burner of claim 19 wherein said rotor rotates in response to and by way of reaction to the issuance of gas under pressure through said rotor chamber inlet port.
21 . The burner of claim 19 wherein rotation of said rotor creates a pulsating flow of gas into said combustion chamber.
22 . A device for generating a controlled pulsating flame in a combustion burner, said device comprising:
a chamber including a cylindrical sidewall with inner and outer surfaces, an inlet port in communication with a source of pressurized gas and an outlet port, said chamber configured for housing a rotor therein;
a rotor rotatably mounted within said chamber, said rotor including at least two radially extending, circumferentially spaced wings, said rotor has a diameter substantially equal to a diameter of the inner surface of said chamber, said wings each including an end face with an indention formed therein; and
at least two rotating cavities formed between said rotor wings, said cavities configured for receiving pressurized gas from said chamber inlet port and transferring said pressurized gas to said chamber outlet;
wherein the pressurized gas entering said chamber causes the rotor to rotate.
