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-route it into the boiler system.Get Price
