OPTIMIZATION OF LOW-BTU FUEL-FIRED COMBINED-CYCLE POWER PLANT BY PERFORMANCE HEATING

摘要

PROBLEM TO BE SOLVED: To enhance plant performance of a combined-cycle power plant. SOLUTION: An optimum approach is presented for enhancing plant performance by carrying out performance heating using bleed-off of compressed air flow from a gas turbine compressor (240) in the combined-cycle power plant (200). In one embodiment, a diverted portion of a by-product off gas and the bleed-off of compressed air flow are fired and heated to produce a high temperature flue gas (285) that is used to performance-heat a pressurized mixture of fuel prior to being supplied to a gas turbine combustor (245).
