Customized Experience Significant Savings With Our High-Efficiency Boiler Economizer
Product Description
The economizers typically consist of a series of pipes arranged in parallel, often in a curved shape to increase the contact area between the flue gas and the incoming water. The flue gas passes through the boiler combustion chamber and enters the economizer, where it flows in the pipe. At the same time, the inlet water of the boiler also passes through the pipes of the economizer and exchanges heat with the flue gas. The heat in the flue gas is transferred to the inlet water, which lowers the flue gas temperature and increases the inlet water temperature. In this way, the heat in the flue gas is recovered and the thermal efficiency of the boiler is improved.
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.
