Cast Iron Oil Boiler Stack Economizer , Chemical Industry Boiler Repair Parts

Product Description

2017 New Design Oil Boiler With Economizer For Chemical Industry

Function of economizer
 
1. Economizer is a device installed in the lower part of the flue of the tail of the boiler for recovering the residual heat of the exhaust gas.
 
2. The boiler feed water is heated to the heated surface of the saturated water under the pressure of the steam drum.
 
3. Since it absorbs high-temperature smoke Gas heat, reducing the exhaust gas flue gas temperature, save energy, improve efficiency, so called economizer.
 
 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.
 
The role of economizer
 
1. Economizer is the use of waste heat boiler exhaust heat to heat the water heat exchanger
 
2. Due to Into the steam drum water, economizer to improve the water temperature, reducing the thermal stress caused by temperature difference drum wall, thereby improving the working conditions drum, extended drum life.
