Energy Management Practices for Improving Energy Efficiency in Industries: Furnace, Steam Boiler, HVAC, and Cooling Systems

Abstract

The aim of this study is to demonstrate and analyse energy management practices to increase energy efficiency in industries. In the study, examples of energy efficiency increasing applications that can be carried out in industrial organizations were discussed and the amount of savings for these applications was calculated. The main energy efficiency applications discussed in the study are the heat recovery in boilers and furnaces, thermal insulation, and heat recovery in HVAC systems. As a result of this study, with energy management and energy efficiency applications, 38.2% of heat recovery and 15.79% of fuel savings were achieved when recuperators were used in the furnace. While the boiler thermal efficiency was 64.46% when the recuperator was not used, the boiler thermal efficiency increased to 76.54% when the recuperator was used. In HVAC systems, heat recovery was achieved with 47% efficiency with the recuperator, heat exchanger with 51% efficiency and 1.09 COP in heat pump. In cooling applications, 30.4 % energy saving was achieved in the insulated room.
