Product Description

Gele Fin Tubes Radiator For Boiler Economizer, Cast Iron Tube Boiler Parts

Product description
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. Steel tube economizer is not pressure limited, can be used as a boiling type, usually by the outer diameter of 32 to 51 mm made of carbon steel.
Product advantages
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.
3. Water temperature increased, into the drum will reduce the wall temperature difference, a corresponding reduction in thermal stress to extend the drum life
Economizer classification
1. According to the degree of water is heated: can be divided into non-boiling and boiling two.
2.  According to the form of device points: There are two vertical and horizontal.
3. According to the relative flow of smoke and water points: There are cis, countercurrent and mixed three.
4. According to the form of thermal conduction: direct conduction and indirect conduction
