What Is An Economizer?

Economizers are mechanical devices designed to low energy consumption or perform a useful function like preheating a fluid. An economizer for a boiler may have vertical, horizontal, or cylindrical orientation and depends on boiler size and space available, and it is fitted directly to the boiler near the flue gas outlet.

How Does It Work?

In a boiler system, an economizer is crucial to capture the heat of the flue gas and transfer it to the feed water. The process is not complicated. As the flue gas goes out of the boiler, it takes entry into the economizer with finned tubes. The finned tubes absorb the heat and thus raise the temperature of the boiler feed water. And all these lower the needed energy input.

Why Add an Economizer?

After adding an economizer you will see an increase in your boiler efficiency and also you will see a reduced amount of energy required for heating resulting in reduced fuel consumption and cost. For an efficient and budget-friendly economizer, contact O’Brien Boiler Services Pty Ltd. This is a leading boiler economiser supplier with years of experience and expertise. 

Boiler Manufacturers worldwide are dedicated to designing and manufacturing efficient and cost-effective boilers. In a Steam Boiler, steam generation happens through the burning of fuels leading to flue gases. Boiler water in steam boilers gets heated with flue gases and turned into steam, which is released for processing operations in industries. After the steam is generated, the flue gases leave the boiler.

It depends on the process operations whether the design of the economizer is going to be a smoke tube or a water tube. In the smoke tube economizer, there are flue gases inside the tube, and the water is in the shell. On the other hand, for the water tube economizer, flue gases are placed in the shell, and the water is in the tubes.
