• ### How can we find enthalpy of boiler feed water? - Quora

Boiler Efficiency It is a well known fact that the initial cost of boiler is a small part of total costs associated with the boiler over its lifetime. In the operational life of a boiler, major costs arise out of the fuel costs. Ensuring efficient

H = enthalpy of one kg of steam leaving the boiler plant and . h = the enthalpy of one kg of water entering the boiler plant. Heat carried away by flue gases . H g = m g C pg (t g1 – t g2) m g = mass of flue gases per kg of fuel fired . C pg = specific heat of dry flue gases (t g1 – t g2) = rise in temperature of flue gases.

Specific Enthalpy of Superheated Steam. The specific enthalpy of superheated steam can be calculated from: h s = h g + c ps (t s - t f) (5) where. h s = enthalpy of superheated steam (kJ/kg) c ps = specific heat of steam at constant pressure = 1.860 (kJ/kg o C) t f = saturation temperature (o C) t s = superheated steam temperature (o C)

Jul 01, 2017 · INTRODUCTION In this work, a new concept for the feed water control of a once- through boiler is introduced and developed. Once-through boil- ers are designed for continuous flow of the evaporating working fluid. This means that the feed pump supplies the feed water to the boiler and successively to the economizer, evaporator and superheater.
