ABSTRACT: An enclosure in which energy in a no thermal form is converted to heat especially such an enclosure in which heat is generated by a combustion of a suitable fuel is known as furnace. The two furnaces lined with fire clay refractory use diesel as their source of fuel. In this paper structure-operation and fuel type- fuel combustion approaches are used to determine the efficiencies of the two furnaces. The result shows that the efficiency values for crucible and rotary   furnace are found to be.
