EISG Project Title: Method of Improving Efficiency of Combined Cycle Power Plants
EISG Grant Number: 00-28
PIER Area: Environmentally Preferred Advanced Generation
Principal Investigator: Robert Surette
Contact Information: (323) 669-0072 r.surette@att.net
Organization: Energy Constructs
Grant Amount: $63,500
Grant Term: 4 Months
Project Description:
The purpose of this project is to research the feasibility of using an ejector-diffuser on gas turbine exhaust nozzles to reduce backpressure and provide uniform flow distribution into the heat exchangers on combined cycle power plants. Computational fluid dynamics (CFD) analysis will be employed to optimize the design geometry.
Proposed Outcomes:
· Working CFD model
· Quantified pressure recovery potential
· Demonstrated potential for stabilizing the boundary layer in the transition layer
Anticipated Benefits:
· Increased efficiency by potentially a half of one percent
· Easy to retrofit
· Potential payback of 2-3 years
