Economizers | CleanBoiler.o

Stack Economizers should be considered as an efficiency measure when large amounts of make-up water are used (ie: not all condensate is returned to the boiler or large amounts of live steam are used in the process so there is no condensate to return) or there is a simultaneous need for large quantities of hot water for some other use.

Economiser in Thermal Power Plant - electrical4u.c

Function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler. It is simply a heat ex-changer with hot flue gas on shell side and water on tube side with extended heating surface like Fins or

Usually they are found only on water tube boilers using fossil fuel as an energy conservation measure. A feedwater economiser reduces steam boiler fuel requirements by transferring heat from the flue gas to incoming feedwaer. By recovering waste heat, an economiser can often reduce fuel requirements by 5 per cent to 10 per cent and pay for

Fired tube boilers consist of a series of straight tubes that are housed inside a water-filled outer shell. The tubes are arranged so that hot combustion gases flow through the tubes. As the hot gases flow through the tubes, they heat the water surrounding the tubes. The water is confined by the outer shell of boiler.
