Abstract
Surfaces of the static blades of a turbine are heated by means that a high temperature, high pressure working gas or heating gas passes through inner passages formed inside the static blades, so that the working gas which passes through interspaces defined between adjacent ones of the static blades expands nearly isothermally without a descent in temperature so as to boost an output of the turbine.
Claims2
A turbine having an entrance, a heat exchanger where a heating gas heats and reheats a working gas, said heat exchanger having a heating element and a reheating element therein, and static blades and dynamic blades, and interspaces defined between adjacent ones of the static blades, said static blades having passages formed inside the blades, an inlet to said passages, and an outlet from said passages, a conduit to conduct said working gas from said reheating element to said inlet, a conduit to conduct said working gas from said outlet to said heating element, whereby the working gas passes serially into each blade through its inlet, through the passages thereof, and flows out through the outlet into said heating element to be heated, a conduit to conduct the heated working gas from said heating element to said turbine to then enter the turbine through its entrance and feed into said interspaces to thereby act on the dynamic blades of the turbine to rotate the dynamic blades, and a conduit to conduct said working gas from said turbine back to said reheating element to be reheated.
