Heat Recovery with Boiler Stack Economizers


INCREASING THE ENERGY EFFICIENCY OF BOILER AND …Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is …Effects of installing economizers in boilers used in space …The non-condensing section of the economizer recovers energy by preheating the boiler feedwater. The condensing section preheats virtually any cool liquid stream (makeup water, wash water, hot water preheating, etc.), and the control system maximizes condensing when firing natural gas, then automatically switches to a near-condensing mode when firing #2 oil (if applicable).
