Temperature and Latent Heat Estimation for Saturated Steam

TEMPERATURE AND LATENT HEAT ESTIMATION FOR SATURATED STEAM 

The following expressions can be used to estimate the temperature and enthalpy of steam. The expressions are based upon multiple regression analysis. The equation for temperature is accurate to within 1.5 % at 1,000 psia. The expression for latent heat is accurate to within + 3 % at 1,000 psia. Input data required to use these equations is the steam pressure in psia. The parameters in the equations are defined as t for temperature in F, for latent heat in Btu/lb, and P for pressure in psia.

The most common heat carrier for heating industrial reactors is steam, providing an efficient and simple means. The efficiency of steam is due to its high latent heat of condensation (AHv = 2260 kj kg1 at 100 °C). For saturated steam, the temperature can be controlled by its pressure. Some values are presented in Table 9.1. The pressure and latent heat of evaporation corresponding to a given temperature may easily be estimated using Regnault law ...
