we will find all losses
% heat loss in dry flue gas = (m(dfg)× Cp(fg)×( T(fg ) T(a)))/(G C.V)× 100
L1
% Heat loss due to evaporation of water due to H2 in fuel (%) =(9×H2×{ 2443.456+ Cp(s) (T(fg) -T(a)})/(G C.V.)× 100
L2
% Heat loss due to moisture in fuel= (m(w)×{ 2443.456+Cps (T(fg)- T(a) })/(G C.V.)× 100
L3
% Heat loss due to moisture in air = (AAS ×humidity factor×Cps (T(fg) -T(a)})/(G C.V.)
L4
% Heat loss due to Partial combustion of C to Co = 0 (complete combustion)
L5
% Heat loss due to radiation and convection = for power station boiler is 3%

(1) Direct Method
where
- m(s) Mass of steam generated
- m(f) mass of fuel consumed
- h(s) enthalpy of steam produced
- h(f.w) enthalpy of feed water
- L.C.V low calorific value of the fuel
Boiler efficiency = η= (24040.4 ( 3207.5 – 567.8 ) )/(2671.659×41565.62)×100
And the same for the rest of the boilers
Introduction
In this project we will do thermal analysis for the power house of Aden refinery. We are going to cover the major components for the station and their performance and showing diagrams and some pictures of the components.
layout diagram of the power plant
This presentation will be as follows
(2) indirect method
boiler efficiency
to do this method we first need to determine the composition of the fuel( heavy fuel in this case with s= 0.937
G.C.V = 18920 btu/lb = 44007.92 kJ/kg
N.C.V = 17870 btu/lb = 41565.62 kJ/kg
- Performance calculations of boiler.
- Performance calculations of steam turbine .
- Performance calculations of THE CONDENSER .
- Heat balance of major components like (superheater, air preheater etc).
- thermal analysis for the distillation plant
