IMPROVING BOILER EFFICIENCY BY USING AIR PREHEATER

Boiler Efficiency - an overview | ScienceDirect Topics

Use of air preheaters to transfer energy from stack flue gases to combustion air. The stack flue gas heat recovery equipment (i.e., air preheaters and economizers) are typically the most cost-effective auxiliary equipment that can be added to improve the overall thermal efficiency of the boiler system.

Combustion Air Preheater

The combustion air preheater is a system that adds heat energy to the boiler intake air in order to reduce the amount of fuel oil needed to produce the same amount of steam. Since roughly 16 percent of the input energy is lost through the exhaust stack to atmosphere, a combustion air preheater has ample opportunity to recapture energy and re
