Gas turbine fuel heating apparatus

摘要

Object: To provide a gas turbine fuel heating apparatus in which an initial investment cost is made low and a contact of high temperature air and fuel at the time of fuel leakage is prevented so that safety is ensured. Construction: There are provided a turbine cooling air cooler 1 of air cooling type for cooling a turbine cooling air and a fuel heater 4 provided connectedly to the leaving side of a refrigerant air of said turbine cooling air cooler 1 of air cooling type for heating the fuel by said refrigerant air. Thereby, an initial investment cost is made low, and said turbine cooling air cooler 1 of air cooling type and said fuel heater 4, respectively, is a separate unit so that a contact of high temperature air and fuel at the time of fuel leakage is prevented. <IMAGE>
