Boiler efficiency question
Boiler efficiency question
(OP)
Hi guys i am getting some trouble with a boiler question here. i am looking for guidance.
i am to find the fuel consumed in a boiler.
given:
steam flow rate
superheated temperature
feed water temperature
pressure
boiler efficiency
calorific value of fuel
and the cp of the superheated steam
my question is how to i calculate the enthalpy of the feed water to plug that back into the boiler efficiency equation?
i would normally go into the steam tables but they specified that they should not be used
if anyone could help me it would be much appreciated

There are calculators available online too. Google "enthalpy of water."
Good on ya,

RE: Boiler efficiency question
how exactly should i use the cp value in my calculations?
this is the only thing keeping me back rite now. I have a feeling it is used somehow to help calculate the feed water enthalpy
