  • Thermal Design of Economizer for Waste Heat Recovery

    2019-7-1 · P.Ravindra Kumar One of the most cost effective ways of improving the efficiency of a high pressure steam boiler is to install an economizer on the boiler. Typically, on a high pressure water tube boiler, the efficiency improvement with an economizer is 2 to 4%, depending on firing rate. On a high pressure fire tube boiler, the improvement is 2 to 3.5%, depending on boiler size and firing rate. As the temperature difference between two working media is small, economizer needs a very large heat exchange surface. The regenerative feed water preheating, this heats the feed water up to the temperature of 200 to300 ˚C before it enters the economizer and which lets the flue gas cools down to the temperatures of, at most above the level determines the fireside outlet temperature of depending on the Terminal Temperature Difference (TTD) of the economizer. The Present work is to carry out by providing an additional bank of tubes in the economizer …
