The image above represents %heat loss through furnace skin. To calculate the %heat loss through furnace skin, two essential parameters are needed, and these parameters are Heat Loss from Roof and Walls (HRW) and Area of Roof and Walls (ARW).
The formula for calculating %heat loss through furnace skin:
%QLÂ = 100(HRW/ARW)
Where:
%QLÂ = %Heat Loss through Furnace Skin (Roof)
HRWÂ = Heat Loss from Roof and Walls
ARWÂ = Area of Roof and Walls
Let’s solve an example;
Find the %heat loss through furnace skin when the heat loss from roof and walls is 15 and the area of roof and walls is 3.
This implies that;
HRW = Heat Loss from Roof and Walls = 15
ARW = Area of Roof and Walls = 3
%QLÂ = 100(HRW/ARW)
%QLÂ = 100(15/3)
So, %QL = 100(5)
%QL = 500
Therefore, the %heat loss through furnace skin is 500%.
Calculating the Heat Loss from Roof and Walls when the %Heat Loss through Furnace Skin and the Area of Roof and Walls are Given
HRW = %QL x ARW / 100
Where;
HRWÂ = Heat Loss from Roof and Walls
%QLÂ = %Heat Loss through Furnace Skin (Roof)
ARWÂ = Area of Roof and Walls
Let’s solve an example;
Find the heat loss from roof and walls when the %heat loss through furnace skin is 20 and the area of roof and walls is 12.
This implies that;

%QL = %Heat Loss through Furnace Skin (Roof) = 20
ARW = Area of Roof and Walls = 12
HRW = %QL x ARW / 100
HRW = 20 x 12 / 100
That is, HRW = 240 / 100
HRW = 2.4
Therefore, the heat loss from roof and wall is 2.4%.

Calculating the Area of Roof and Walls when the %Heat Loss through Furnace Skin and the Heat Loss from Roof and Walls are Given
ARW = 100 x HRW / %QL
Where;
ARWÂ = Area of Roof and Walls
%QLÂ = %Heat Loss through Furnace Skin (Roof)
HRW = Heat Loss from Roof and Walls
Let’s solve an example;
Find the area of roof and walls when the %heat loss through furnace skin is 14 and the heat loss from roof and walls is 8.
This implies that;
%QL = %Heat Loss through Furnace Skin (Roof) = 14
HRW = Heat Loss from Roof and Walls = 8
ARW = 100 x HRW / %QL
Then, ARW = 100 x 8 / 14
ARW = 800 / 14
ARW = 57.14
Therefore, the area of roof and walls is 57.14%.
