Steam Boiler Spare Parts High Strength Cast Iron Material H Fin Tube Economizer

Product Description

Steam Boiler Component H Fin Tube Economizer In Heat Exchanger

Function of economizer
 
1. Absorb the heat of low temperature flue gas, reduce the exhaust gas temperature, reduce exhaust loss, save fuel.
 
2. Because the feed water into the drum before the economizer heating, thus reducing the heat in the heating surface of the water supply, you can use economizers to replace some of the higher cost of evaporation heating surface.
 
Prevent corrosion of economizer measures
 
1. The main ways to prevent or reduce the corrosion in the economizer tube are: to improve the deaeration efficiency of the deaerator and to reduce the SO2 generation in the flue gas.
 
2. Deaerator to improve the oxygen removal efficiency is to control the oxygen content of boiler feed water to reduce oxygen corrosion
 Economizer classification
 
1. According to the form of device points: There are two vertical and horizontal.
 
2. According to the relative flow of smoke and water points: There are cis, countercurrent and mixed three.
 
3. According to the structure of the points: light pipe economizer and fin economizer. Finned economizers include: H-type economizer (more used) and spiral fin economizer.
