摘要

PROBLEM TO BE SOLVED: To prevent damage to a gas turbine combustor in the case of the mixing of feed water into fuel when a fuel heating apparatus for preheating the fuel for a gas turbine is damaged. SOLUTION: The feed water heated by an economizer is used as a heat source of the fuel heating apparatus in a fuel supply system at a gas turbine inlet, and a humidity separator is installed in the wake of the fuel heating apparatus for free water to be separated from the fuel and discharged out of a fuel system in case of the mixture of the feed water into the fuel system when the fuel heating apparatus is damaged.
