Abstract (en)

A heating element (50) with heating coils is extended over the entire length of the hollow space (38) behind the leading edge (36) of a guide vane profile. The heating element also runs from inside to outside platforms (34a,34b) of the vane profile, and gradually preheats the vane especially at time of cold starting of the gas turbine. Independent claims are included for the following: (1) a use of a gas turbine guide vane; and (2) a method of operating a gas turbine.
