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.
Function of economizer
1. Economizer is the use of waste heat boiler exhaust heat to heat the water heat exchanger
2. Economizer to absorb exhaust heat, reduce exhaust gas temperature and improve boiler efficiency
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
3. To reduce the SO2 in the flue gas is not only to reduce the flue gas dew point temperature, but also to reduce the condensation of sulfuric acid vapor.
