Introduction An energy audit is an evaluation of energy consumption in a home, business or any other premises such as college institutions, government institutions and ofces, as well as industrial structures such as factories and manufacturing units. An energy audit is generally used to determine where energy can be saved, conserved or used more efciently. With the world facing energy crisis and the lack of attention towards efcient energy use in industrial sector poses a great concern for the energy management teams in the industries. For this purpose, this work targeted the various opportunities and possibilities of fnding solutions to the energy wastage and energy conservation in one of the foundry plant located at MIDC Amravati (Maharashtra, India). An energy audit is carried out within the foundry. Te audit consisted of two main phases: a pre-audit phase that focused on identifying energy consumption points in the foundry unit such as various machines, water pumps, lighting etc and determining the energy wastage at these points. 2. Energy Audit Objectives • Te First objective was to acquire data by observations, analyzing the data and fnding the energy consumption pattern of the facility. Abstract Objectives: Implementing energy conservation in foundries, identification of energy losses from induction furnace in the form of conduction and radiation heat losses. Method/Approach of Energy Audit: The energy audit in this work consists of two phases and this piece of work focuses on the second phase which consists of identification and determination of conduction and radiation heat losses from induction furnace. A comparison for different values of furnace lining thickness shows conduction losses for each value of furnace lining thickness. The radiation losses are identified and the combined total losses are calculated. Findings/Observations: The conduction losses remain practically the same for all the operating temperatures of the furnace for a given thickness of furnace lining. The conduction losses are different for different values of furnace lining thickness. They increase as the lining thickness of furnace is increased. Radiation losses remain practically the same for all values of lining thickness for the entire operating temperature range. Radiation losses occur from the furnace opening and increases as the temperature of the furnace is increased. Thus, for the original thickness of 63 mm, the maximum and minimum heat efficiency is 93.1% at 1200°C and 86.27% at 1500°C respectively. The furnace does operate at an overall average heat efficiency of about 90% with a deviation of about ± 3% for a given value of thickness. Application/Improvements: A good energy management is the key towards energy conservation and it starts with an energy audit. The detailed energy audit analysis reveals good amount of energy saving in foundry and allied industries.
