In this case study, the define phase evaluates the furnace performance, through identifying and reducing
multiple operational energy losses to improve the overall efficiency. The Pareto chart in Fig.1 reveals that,
numerous opportunities for improving the performance of the furnace. Among numerous opportunities, the waste
heat recovery system saves up to 30% energy by transferring excess thermal energy to essential parts, especially for
the combustion chamber to reduce high fuel consumption for obtaining required operating temperature. The heat
generation parameter which includes proper air fuel ratio, reducing the excess air, enriching oxygen and preheating
combustion air provides 25% energy savings. Heat containment saves 15% of energy by the reduction of energy loss
to the surroundings, through inspecting convection, radiation and opening losses. The heat transfer saves 10% of
energy loss by the removal of carbon deposits and maintaining a clean surface
