Hybrid two fuel system nozzle with a bypass connecting the two fuel systems
A hybrid fuel combustion nozzle for use with natural gas, syngas, or other types of fuels. The hybrid fuel combustion nozzle may include a natural gas system with a number of swozzle vanes and a syngas system with a number of co-annular fuel tubes.
1. A hybrid fuel combustion nozzle for use with a flow of natural gas, syngas, or other types of fuels with a flow of air, comprising:
a natural gas system;
the natural gas system comprising a fuel flowing through an injection port in at least one of a plurality of swozzle vanes;
a syngas system;
the syngas system comprising a plurality of co-annular fuel tubes placed radially inward of said swozzle vanes to provide a co-flow of the flow of natural gas, syngas, or other types of fuel and the flow of air; and
a by-pass fuel line extending from the plurality of co-annular fuel tubes to the plurality of swozzle vanes for delivering a portion of the syngas through the swozzle vane injection port of the natural gas system.
2. The hybrid fuel combustion nozzle of claim 1 , wherein the natural gas system comprises a natural gas inlet in communication with the plurality of swozzle vanes.
3. The hybrid fuel combustion nozzle of claim 1 , wherein the syngas system comprises a syngas inlet in communication with the plurality of co-annular fuel tubes.
4. The hybrid fuel combustion nozzle of claim 1 , wherein the plurality of co-annular fuel tubes comprises a plurality of orifices and/or a plurality of injection ports.
5. The hybrid fuel combustion nozzle of claim 1 , wherein the syngas system comprises a center syngas port.
6. The hybrid fuel combustion nozzle of claim 1 , further comprising a plurality of openings positioned about the plurality of swozzle vanes and in communication with the syngas system.
7. The hybrid fuel combustion nozzle of claim 1 , further comprising one or more air ports.
8. A hybrid fuel combustion nozzle for use with a number of different types of fuels and a flow of air, comprising:
a first gas system;
the first gas system comprising a fuel flowing through an injection port in at least one of a plurality of swirl vanes;
a second gas system;
the second gas system comprising a plurality of co-annular fuel tubes placed radially inward of said swirl vanes to provide a co-flow of a second fuel and the flow of air; and
a by-pass fuel line extending from the plurality of co-annular fuel tubes to the plurality of swirl vanes for delivering a portion of the second fuel through the swirler vane injection port of the first gas system.
9. The hybrid fuel combustion nozzle of claim 8 , wherein the plurality of fuel tubes comprises a plurality of co-annular fuel tubes.
10. The hybrid fuel combustion nozzle of claim 8 , wherein the plurality of fuel tubes comprises a plurality of orifices and/or a plurality of injection ports.
11. The hybrid fuel combustion nozzle of claim 8 , wherein the second gas system comprises a center gas port.
12. The hybrid fuel combustion nozzle of claim 8 , further comprising a plurality of openings positioned about the plurality of swirl vanes and in communication with the second gas system.
