Course Outline
This one hour online course discusses some of the basic waste heat reduction and recovery opportunities for improving furnace efficiency, productivity and emissions performance.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
Learning
Objective
At the conclusion of this course, the student will learn about:
- Heat losses from fuel-fired heating equipment;
- Steps for increasing energy efficiency through reduction in exhaust gas heat losses; and
- Improving the performance of existing equipment.
Intended Audience
This course is intended for mechanical, energy and facility engineers.
Benefit for Attendee
Attendee of this course will be able to understand waste heat reduction and recovery for improving furnace efficiency, productivity and emissions performance.
Course Introduction
Waste-gas heat losses are unavoidable in the operation of all fuel-fired furnaces, kilns, boilers, ovens, and dryers. Air and fuel are mixed and burned to generate heat, and a portion of this heat is transferred to the heating device and its load. Reducing these losses should be a high priority for anyone interested in improving the energy efficiency of furnaces and other process heating equipment.
Course Content
This course is primarily based on 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:

Course Summary
This course discusses how obtaining the maximum efficiency and productivity from industrial furnaces and ovens is a two-step process. First, getting the equipment up to its peak performance by reducing heat losses, improving production scheduling and closely controlling gas-air ratios. Once the equipment has reached this level of performance, additional significant improvements may come from recapturing waste heat through direct load preheating, combustion air preheating or steam generation.
