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 of unit,
capital cost and operating cost for each of the
three methods of heat recovery.
