Description
Economizers are mechanical devices intended to reduce energy consumption,or to perform useful function such as preheating a fluid.In simple terms,an economizer is a heat exchanger.
Economizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant. In an HRSG, water passes through an economizer, then a boiler and then a superheater. The economizer also prevents flooding of the boiler with liquid water that is too cold to be boiled given the flow rates and design of the boiler.
The technology of H-fin tube economizer is a high-efficiency heat transfer economizer assembled by H-fin tube (also known as H-fin tube, rib tube and butterfly tube).The basic form is "H" type and double "H" type, arranged in sequence.
Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.HD BOILER has also completed stand-alone product quality assurance systems.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.
Function
1. Absorb the heat of low-temperature flue gas, reduce the smoke exhaust temperature, reduce smoke loss and save fuel.
2. Since the feed water is heated in the economizer before entering the 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 high-cost evaporative heating surface.
3. When the feed water temperature is raised, the wall temperature difference will be reduced and the thermal stress will be correspondingly reduced to extend the service life of the steam drum.
