Abstract
A method and a device for determining an enthalpy of wet steam, in particular of wet steam at an outlet of a steam turbine. A part volume flow of the wet steam is mixed with a reference gas to form a mixture, so that the liquid constituents of the part volume flow evaporate completely. An enthalpy of the reference gas and an enthalpy of the mixture is then determined by measured physical variables and an enthalpy of the wet steam is calculated from these enthalpies.
