The image above represents %heat loss from openings in furnace. To calculate the %heat loss from openings in furnace, five essential parameters are needed and these parameters are Black Body Radiation (BR), Emissivity (E), Radiation Factor (RF), Quantity of Oil (Q) and Gross Calorific Value of Oil (GCVoil).
The formula for calculating %heat loss from openings in furnace:
%QLÂ = 100(BRÂ x E x RF/Q x GCVoil)
Where:
%QLÂ = %Heat Loss from Openings in Furnace
BRÂ = Black Body Radiation
E = Emissivity
RFÂ = Radiation Factor
Q = Quantity of Oil
GCVoil = Gross Calorific Value of Oil
Let’s solve an example;
Find the %heat loss from openings in furnace when the black body radiation is 15, the emissivity is 6, the radiation factor is 3, the quantity of oil is 24 and the gross calorific value of oil is 9.
This implies that;
BR = Black Body Radiation = 15
E = Emissivity = 6
RF = Radiation Factor = 3
Q = Quantity of Oil = 24
GCVoil = Gross Calorific Value of Oil = 9
%QLÂ = 100(BRÂ x E x RF/Q x GCVoil)
%QLÂ = 100(15 x 6 x 3/24 x 9)
So, %QLÂ = 100(270/216)
%QL = 100(1.25)
%QL = 125
Therefore, the %heat loss from openings in furnace is 125%.
