Coal-Fired Biomass Boiler Economizer For Power Station With Spiral Fin
How to prevent low-temperature corrosion?
Maintain feedwater temp > <｜place▁holder▁no▁479｜> + corten steel/coating.
Product Description
The economizer is a heat exchanger that uses the exhaust heat of the boiler to heat the feed water, which is arranged under the first-stage superheater of the flue after the tail shaft. The economizer is composed of a flue, a kettle, an inlet and outlet flange, etc. The function is to use the flue gas heat to heat the feed water, so that the feed water temperature entering the steam drum is close to the temperature of the saturated water under the pressure of the steam drum, so as to reduce the heat exchange in the furnace, reduce the heat exchange area, save fuel, use the waste heat of the flue gas, reduce the exhaust gas temperature, and improve the efficiency of the boiler.

Features
Function
1. Absorb the heat of low-temperature flue gas, reduce the exhaust temperature, reduce the exhaust loss, and save fuel.
2. Because the feed water is heated in the economizer before entering the steam drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace part of the evaporation heating surface with high cost.
3. When the feed water temperature increases, the wall temperature difference will be reduced when it enters the steam drum, and the thermal stress will be reduced accordingly, prolonging the service life of the steam drum.
Energy-saving principle
Add a reheating process to the cycle. Increase the average temperature of endothermy. This increases the efficiency of the cycle. During the start-up process of the boiler (drum boiler), because the circulation of its steam-water pipeline is not established, that is, the boiler feed water is in a stagnant state, and the water in the economizer is in a state of non-flow at this time. With the strengthening of boiler combustion and the increase of flue gas temperature, the water in the economizer is easy to vaporize, so that the part of the economizer is in an overtemperature state. In order to avoid this situation, a pipe is connected from the centralized sewer pipe of the steam drum to the inlet of the economizer as a recirculation pipe, so that the water in the economizer is in a flowing state to avoid its vaporization.
