Method and apparatus for heating liquid fuel supplied to a gas turbine combustor

摘要

A method of heating liquid fuel upstream of a combustor in a system where compressor discharge air is cooled before being supplied to fuel nozzles in the combustor includes the steps of passing the compressor discharge air through a heat exchanger in heat exchange relationship with the liquid fuel to heat the liquid fuel and cool the compressor discharge air; supplying the heated liquid fuel and the cooled compressor discharge air to the combustor.

1. A method of heating liquid fuel upstream of a combustor in a system where compressor discharge air is cooled before being supplied to the combustor, the method comprising:
(a) applying heat from the compressor discharge air to the liquid fuel in a heat exchanger in a liquid fuel supply circuit as the liquid fuel passes through the heat exchanger; (b) supplying the heated liquid fuel to the combustor; and (c) supplying compressor discharge air exiting the heat exchanger directly to an atomizing air cooler upstream of a moisture separator in a compressor discharge atomizing air system.
