A boiler economizer is a heat exchanger that recovers waste heat from flue gases to preheat boiler feedwater, thus improving overall boiler efficiency and reducing fuel consumption. It acts as a cost-effective solution for saving energy and money by utilizing the otherwise wasted heat from the boiler’s exhaust. How it works: Hot flue gases...

Boiler Economisers can be classified in various ways depending on the economizer’s function and operation. An economizer can be made pressurized or non-pressurized depending on the required water temperature through it. Thermodyne manufactures both Pressurized Economisers as well as non-pressurized Economisers to suit your needs. Generally, If...

The function of the Boiler Economizer The Economizer in Boiler works on the principle of Heat Transfer. Heat transfer usually takes place from high temperature to low temperature. In the case of Boilers, flue gases or exhaust from the boiler outlet are at high temperature and water that needs to be preheated is at low […]

Boiler economizers work by transferring heat from the flue gases to the boiler feedwater. The flue gases are typically hot, around 300-500 degrees Fahrenheit, and the boiler feedwater is typically cold, around 100-150 degrees Fahrenheit. The heat from the flue gases is transferred to the boiler feedwater, which raises the water’s temperature. The...
