Flue gases from large boilers are typically 450 – 650°F. Gas Economizers recover some of this heat for pre-heating water. The water is most often used for boiler make-up water or some other need that coincides with boiler operation. Gas 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...

Tubular preheaters consist of straight tube bundles which pass through the outlet ducting of the boiler and open at each end outside of the ducting. Inside the ducting, the hot furnace gases pass around the preheater tubes, transferring heat from the exhaust gas to the air inside the preheater. Ambient air is forced by a fan through ducting at one end of the preheater tubes and at other end the heated air from inside of the tubes emerges into another set of ducting, which carries it to the...

Product details: Coal power plant steam boiler air preheaters can be classified as tubular, recuperative or regenerative based on their operating principle. The first two are usually found in steam generators in thermal power plants. In the recuperative type, fluid (such as flue gas) is warmed through energy that is passed through a heat absorbing surface such as a metallic tube or plate. The captured heat is released into the cooler air and directed back into the boiler. We could provide whole...
