Abstract

A method and apparatus for determining the steam temperature in the impulse chamber at the first stage exit of a multistage high pressure steam turbine utilizes measurement of steam pressure in the impulse chamber and steam pressure and temperature at the exhaust as inputs to a digital computer. The functional relationships among steam pressure, temperature, specific volume, enthalpy and entropy are stored in the computer memory, and used with these measured quantities to iteratively calculate the steam temperature at the impulse chamber.
