The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.
12/29/2014 · During the replacement of an aging central steam plant at Shippensburg University (S.U.) in Shippensburg, Pa., the operating efficiency and sustainability depended on careful selection and specification of condensing hot water boilers.
