High - Efficient Carbon Steel Boiler Parts Fin Economizer In Power Plant
Product Description
The boiler economizer is a very important component in the boiler, which is usually installed in the tail flue of the boiler, adjacent to the air preheater. According to different structural forms and use occasions, the boiler economizers can be divided into different types. The common ones are light tube economizers, fin economizers, membrane economizers, etc. Among them, the plain tube economizer is the simplest form, which is mainly composed of a series of straight pipes, while the fin economizer and membrane economizer add fins or diaphragms on the basis of the plain tube economizer respectively to improve the heat transfer efficiency.

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.
