How Boiler Economizers Work?

29 Mar 2023

Boiler economizers are devices that help to improve the efficiency of industrial boilers by recovering heat from the flue gas and transferring it to the boiler feedwater. In this article, we will explore how boiler economizers work and the benefits they offer. We will also introduce ZOZEN's boiler and economizer solutions that can help improve the energy efficiency of your industrial operations.

How Do Boiler Economizers Work?

A boiler economizer is essentially a heat exchanger that recovers waste heat from the flue gas and transfers it to the boiler feedwater. The feedwater is heated, reducing the amount of fuel needed to bring it up to the required temperature. This results in improved energy efficiency and reduced fuel consumption. In addition, by lowering the flue gas temperature, the economizer reduces the emissions of harmful pollutants such as carbon dioxide, sulfur dioxide, and nitrogen oxides.

The operation of an economizer is relatively simple. As the flue gas exits the boiler, it passes through a series of tubes or channels in the economizer. These tubes are filled with boiler feedwater, which absorbs the heat from the flue gas. The heated feedwater then passes through a series of tubes in the boiler, where it is used to generate steam. This process reduces the energy required to heat the water, and thus, reduces the overall fuel consumption of the boiler.

Advantages of Boiler Economizers

The primary benefit of a boiler economizer is improved energy efficiency. By recovering heat that would otherwise be wasted, an economizer can reduce the fuel consumption of a boiler by up to 5-10%. This can result in significant cost savings over the life of the boiler. In addition, an economizer can help to reduce emissions of harmful pollutants, which is especially important for industries that operate in areas with strict environmental regulations.
