High Efficient Carbon Steel Boiler Economizer In Power Plant , Long Service Life
Boiler Economizer Introduction
Economizer (English name) is installed on the lower part of the
boiler tail flue for recycling the waste heat of smoke, a device
heating boiler feed water into steam drum pressure of saturated
water heating surface, due to its high temperature flue gas heat,
reduces the exhaust temperature of flue gas, save the energy,
improve the efficiency, so called the Economizer.
Steel tube economizer is not limited by pressure, can be used as a boiling type, generally from the outer diameter of 32 ~ 51 mm carbon steel tube.
Fins and fins are sometimes added to the tube to improve heat transfer.
The tubular economizer consists of horizontally arranged parallel elbow pipes (commonly known as serpentine pipes).
Economizers are mainly used in industry, but also gradually spread to agriculture and some related industries on the commercial.

Functions
1.Absorb the heat of low-temperature flue gas, reduce the smoke
temperature, reduce smoke loss, save fuel.
2.Since the feed water is heated in the economizer before entering
the drum, the heat absorption of the feed water on the heating
surface is reduced, and the economizer can be used to replace the
evaporation heating surface with high cost.
3.Feed water temperature increased, into the drum will reduce the
wall temperature difference, thermal stress reduced accordingly,
extend the drum service life.
