ABSTRACT
This chapter summarizes some of the energy efficiency opportunities for process heat applications. The industry technologies are divided into the end-use areas of motors, boilers, process heating, waste treatment, air and water treatment, electrolysis, membrane separation, food and agriculture, and general. Domestic water heating is essential for the comfort and well-being of consumers. Approximately 28% of residential electric energy use can be attributed to space conditioning. Industrial use of electricity is dominated by the use of electric motors, lighting and process heating. Some common retrofit and replacement opportunities for motors and drives are described. Thermal energy storage can also be considered an industrial energy source. The establishment of an energy management program is a crucial part of the process of setting and achieving industrial energy-efficiency goals.
