The image above represents the thermal efficiency of the furnace. To calculate the thermal efficiency of a furnace, two essential parameters are needed, and these parameters are Heat in the Stock (Hs) and Heat in the Fuel for Heating (Hf).
The formula for calculating thermal efficiency of a furnace:
Tf = Hs/Hf
Where:
Tf = Thermal Efficiency of Furnace
Hs = Heat in the Stock
Hf = Heat in the Fuel for Heating
Let’s solve an example;
Find the thermal efficiency of furnace when the heat in the stock is 21 and the heat in the fuel for heating is 7.
This implies that;
Hs = Heat in the Stock = 21
Hf = Heat in the Fuel for Heating = 7
That is, Tf = Hs / Hf
Tf = 21 / 7
Tf = 3
Therefore, the thermal efficiency of furnace is 3.
Calculating the Heat in the Stock when the Thermal Efficiency of Furnace and the Heat in the Fuel for Heating are Given
Hs = Tf x Hf
Where;
Hs = Heat in the Stock
Tf = Thermal Efficiency of Furnace
Hf = Heat in the Fuel for Heating
Let’s solve an example;
Find the heat in the stock when the thermal efficiency of furnace is 10 and the heat in the fuel for heating is 6.
This implies that;

Tf = Thermal Efficiency of Furnace = 10
Hf = Heat in the Fuel for Heating = 6
Then, Hs = Tf x Hf
Hs = 10 x 6
Hs = 60
Therefore, the heat in the stock is 60.

Calculating the Heat in the Fuel for Heating when the Thermal Efficiency of Furnace and the Heat in the Stock are Given
Hf = Hs / Tf
Where;
Hf = Heat in the Fuel for Heating
Tf = Thermal Efficiency of Furnace
Hs = Heat in the Stock
Let’s solve an example;
Find the heat in the fuel for heating when the thermal efficiency of furnace is 5 and the heat in the stock is 30.
This implies that;
Tf = Thermal Efficiency of Furnace = 5
Hs = Heat in the Stock = 30
Hf = Hs / Tf
So, Hf = 30 / 5
Hf = 6
Therefore, the heat in the fuel for heating is 6.
