Abstract
A system including a controller. The controller may receive a signal indicative of an emissions level of a turbine. The controller may also generate at least one control signal. This control signal may control a split of diluent between a first and a second mixing chamber, whereby the first and the second mixing chambers are located in a fuel nozzle in the turbine.
Claims20
A system comprising:
- a fuel nozzle, comprising:
- a first mixing chamber comprising at least one first opening;
- a second mixing chamber comprising at least one second opening;
- a first path configured to supply a first fluid into the first mixing chamber;
- a second path configured to supply a second fluid into the first mixing chamber via the at least one first opening;
- a third path configured to supply a mixture of the first fluid and the second fluid from the first mixing chamber to the second mixing chamber via the at least one second opening;
- and
- a fourth path configured to supply the second fluid to the second mixing chamber.

1 more element
A system comprising:
- a fuel nozzle, comprising:
- a first mixing chamber configured to receive a fuel, a diluent, and a fluid mixture comprising diluent;
- a fuel passage fluidly coupled to the first mixing chamber, wherein the fuel passage is configured to supply the fuel to the first mixing chamber;
- a second mixing chamber fluidly coupled to the first mixing chamber, wherein the second mixing chamber is configured to receive the fluid mixture from the first mixing chamber;
- and
- a plenum fluidly coupled to both the first mixing chamber and the second mixing chamber, wherein the plenum is configured to split the diluent into a first diluent flow into the first mixing chamber and a second diluent flow into the second mixing chamber.
