Product Description
Heat Recovery Boilers Economizer / Economiser Coils SA210M A1 Steel
1. Bare Tube Economizer
Bare tube economizers are commonly used in large power plants and industrial boilers where the quality of feedwater is high and there's less risk of scaling or deposits. Typically, these economizers are made from carbon steel, alloy steel, or stainless steel tubes depending on the operating conditions and corrosiveness of the flue gases.
2.H-Finned Tube Economizer
H -finned tube economizer is high efficient heat exchanger economizer which is considered of H-finned tubes. H-finned tube economizer can enlarge the heat exchange area and reduce the number of tubes. It also can increase the flue gas flow area on order to reduce the flue gas flow speed and abrasion. H-finned tube can be made as double H finned tubes , which high rigidness to fit long tube row.
3. Spiral Finned Tube Economizer
The spiral finned tube economizer is a newly designed heat transfer equipment, consists of spiral fin tubes to overcome the serious abrasion and short service time.
Product Parameters
Product Description
Economizer coils are used in downstream of Boiler bank to preheat the feed water absorbing heat from hot exhaust gases. Economizers are always water tube type. Economizers have different types of Tubes depending upon the application. Bare tubes in Economizers are widely used in Industrial boilers and for applications like Heat recovery boilers in Sulfuric acid plants, gilled tubes are employed. Finned tubes are popular in HRSG applications. Feed water can be heated up to a level about 20 - 30 C below saturation temperature of the boiler.
