Gas turbine plant with fuel heating and turbine cooling features

A gas turbine blade is provided with a hollow blade effective section and a blade implanted section operatively connected to the blade effective section and the gas turbine blade is formed with: a leading edge passage for guiding a cooling medium from a supply passage of the blade implanted section on a blade leading edge side of the hollow blade effective section; leading edge intermediate passages following the leading edge passage; and a trailing edge passage for guiding the cooling medium from a supply passage of a blade implanted section on a blade trailing edge side of the hollow blade effective section. The leading edge passage being provided with a heat transfer accelerating element which is arranged in a right ascendant state inclined to an advancing flow direction of the cooling medium when supplying the cooling medium from the blade implanted section to a blade tip section side or left (leading edge side) ascendant state from the blade tip section to the blade implanted section. The trailing edge passage being provided with a heat transfer accelerating element which is arranged in a left (trailing edge counter side) ascendant state inclined to the advancing flow direction of the cooling medium when supplying the cooling medium from the blade implanted section to a blade tip section side.
