Abstract
The largest single area for industrial energy conservation is in the improvement of combustion efficiencies for heaters and boilers. A number of methods can be employed to recover heat. The most common are by use of recuperative air preheaters, regenerative air preheaters and economizers. Relative advantages and applicability of the three methods are discussed. Analytical methods and correlations are presented which enable determination of size and unit, capital cost and operating cost for each of the three methods of heat recovery.
