Gas turbine plant with fuel preheater
Abstract
The fuel delivery system of a gas turbine plant includes an exchanger for heating the fuel before feeding it to the combustor. The heat energy is provided by hot gases which can be found in the plant, e.g. in the compressor, in its casing, in the discharge of the turbine or preferably in a flowpath bypassing the combustor.
