The economizer is the heating surface of the boiler feed water heated into saturated water under drum pressure in the flue at the tail of the boiler, which reduces the exhaust gas temperature of the flue gas due to the heat it absorbs from the low-temperature flue gas, saves energy and improves efficiency. The economizer consists of a horizontal arrangement of parallel elbow pipes (commonly known as serpentine pipes). Boiler economizer is a device installed at the tail of the boiler for the recovery of waste heat. It is mainly suitable for industry, and in recent years, it has also been popularized in agriculture and some related industries. The economizers produced in our factory are mainly used in the boilers of large power stations.

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.
