Steam Generation Thermodynamics 101 - Power

Main steam is at 2,000 psia, 1,000 F, and has an enthalpy of 1474.1 Btu/lbm. The steam extraction (cold reheat) pressure is 300 psia, which equates (isentropically) to a cold reheat temperature of

Specific Heat Constant for Superheated Steam - Heat

2011-6-15·h(superheated steam) = 1315 Btu/lb However, the steam table give the result of 1355.7 Btu/lb I was hoping someone can explain to me where the difference comes from? Is shomate's equation not valid for superheated steam? If so, is the another formula I could use? Or maybe I am missing something else entirely? Any help would be appriciated.

Corrosionpedia - What is a Saturated Steam? -

Saturated steam occurs when steam and water are in equilibrium. Dry steam is saturated steam that has been very slightly superheated. Saturated steam is used for heating, cooking and drying. Saturated steam is an excellent heat source, particularly at temperatures of 100°C

Corrosionpedia - What is a Superheated Steam? -

Since superheated steam has no direct relationship between temperature and pressure, at a particular pressure it may be possible for superheated steam to exist at a wide range of temperatures. As superheated steam is an insulator, superheated steam farther away from the surface cannot easily cool down and yield its energy.

APPLIED THERMODYNAMICS REVISION OF ISENTROPIC

2015-10-19·For a steam circuit as shown previously, th e boiler produces superheated steam at 50 bar and 400oC. This is expanded to 3 bar with an isentropic efficiency of 0.9. The exhaust steam is used for a process. The returning feed water is at 1 bar and 40oC. This is pumped to the boiler. The water leaving the pump is at 40oC and 50 bar.
