The image above represents %heat loss in flue gas. To calculate the %heat loss in flue gas, four essential parameters are needed and these parameters are Mass (m), Specific Heat of Stock (Cp), Change in Temperature (ΔT) and Gross Calorific Value of Fuel (GCVf).
The formula for calculating %heat loss in fuel gas:
%QL = 100(mCpΔT/GCVf)
Where:
%QLÂ = %Heat Loss in Flue Gas
m = Mass
Cp = Specific Heat of Stock
ΔT = Change in Temperature
GCVf = Gross Calorific Value of Fuel
Let’s solve an example;
Find the %heat loss in flue gas when the mass is 10, the specific heat of shock is 14, the change in temperature is 12 and the gross calorific value of fuel is 18.
This implies that;
m = Mass = 10
Cp = Specific Heat of Stock = 14
ΔT = Change in Temperature = 12
GCVf = Gross Calorific Value of Fuel = 18
%QL = 100(mCpΔT/GCVf)
%QLÂ = 100(10(14)(12)/18)
That is, %QLÂ = 100(1680/18)
%QL = 100(93.33)
%QLÂ = 9333.3
Therefore, the %heat loss of flue gas is 9333.3%.
