Modulating Fan-Powered Economizers - Broadening the applicability of energy recovery

摘要

Though they have been around for decades, stack economizers remain limited by boiler design and exhaust and operating-pressure requirements, which confine them to larger and less efficient industrial steam and hot-water boilers. This article discusses modulating fan-powered economizers, which overcome the challenges faced by traditional economizers and make energy recovery possible for practically any combustion appliance.
