thermal design of economizer for waste heat recovery

Thermal Design of Economizer for Waste Heat Recovery

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.

Improving Boiler Room Efficiencies

traditional economizer is constructed of steel boiler tubes passing through a tube sheet, much like a firetube boiler, or manifolded together like the radiator in your car. As the exhaust effluent passes through or around the tubes it transfers its heat to the feedwater in the shell side of the economizer. This design relates to an average efficiency of 45-75 percent. Rugged and heavy this design typifies most economizer …
