Project Description:
The purpose of this project is to research the feasibility of a new, lean-premix gas turbine combustor design that permits precise local control of the air-to-fuel ratio which improves the operating range of the combustor and significantly reduces NOx emissions. The project includes fabrication and testing of up to 4 prototype combustor configurations and the development and testing of potential control strategies.
Proposed Outcomes:
· Prototype lean-premix gas turbine combustor capable of meeting targeted emissions levels.
· Optimized fuel/air control strategy for prototype combustor.
Anticipated Benefits:
· Reduce NOx, CO and hydrocarbon emissions in lean-premixed gas turbine combustors to 5 ppm, 10 ppm and 10 ppm, respectively.
· California relies heavily on gas turbines for electric generation and low emission gas turbines are expected to play a major role in distributed generation.
