Boiler economizerdetails

Cast iron boilereconomizerIt is a commonly used boiler economizer, also known as economizer tube, used to save energy and improve boiler efficiency. Its working principle is to heat the water in the tail flue of the boiler into bubble pressure, thereby heating the saturated water.
Cast iron boiler economizer tubes are mainly used to absorb the heat of low-temperature flue gas, reduce exhaust gas temperature, minimize exhaust gas losses, and achieve fuel savings; Due to the fact that the feedwater is heated in the economizer before entering the steam drum, the heat absorption of the feedwater on the heating surface is reduced, and the economizer can be used to replace some of the expensive evaporative heating surfaces; As the temperature of the feedwater increases, the wall temperature difference decreases when entering the steam drum, resulting in a corresponding reduction in thermal stress and prolonging the service life of the steam drum.

Detailed content of boiler economizer

Boiler economizer is a device installed at the tail of the boiler for recovering waste heat. Mainly applicable to industry, it has also been popularized in agriculture and some related industries in recent years.

The boiler economizer is a heating surface that heats the boiler feedwater into saturated water under the pressure of the steam drum in the tail flue of the boiler. As it absorbs relatively low temperature flue gas, it reduces the exhaust temperature of the flue gas, saves energy, and improves efficiency, so it is called an economizer.

The boiler economizer is connected to the inlet of the economizer by connecting another pipeline from the centralized sewer pipe of the steam drum to the economizer,As a recycling pipeline,Keep the water in the economizer in a flowing state.Prevent its vaporization
