Waste Heat Reduction & Recovery

Steven G. Liescheidt, P.E., CCS, CCPR

Thermal efficiency of process heating equipment, such as furnaces, ovens, melters, heaters, and kilns is the ratio of heat delivered to a material and heat supplied to the heating equipment. For most heating equipment a large amount of the heat supplied is wasted in the form of exhaust or flue gases. These losses depend on various factors associated with the design and operation of the heating equipment. This technical brief is a guide to help plant operators reduce waste heat losses associated with the heating equipment.

This course is based on the document A Best Practices Process Heating Technical Brief Waste Heat Reduction and Recovery for Improving Furnace Efficiency, Productivity and Emissions Performance, DOE/GO-102004-1975 November 2004.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
