What is the working principle of boiler economizer?
The boiler system consists of boiler body, energy-saving equipment, instrument valves, water treatment and control system, and some will add economizer. Because many users don't know what the working principle of boiler economizer is, here ZOZEN Boiler will answer for you.
Working principle of boiler economizer
Boiler economizer, as its name implies, is a boiler device for saving energy, which is generally installed at the tail of boiler flue and used to recover the waste heat of high temperature flue gas.
The working principle of the boiler economizer is that the flue gas at the tail of the boiler enters the economizer, and the water in the economizer absorbs the temperature in the flue gas through the finned tube, and then returns to the boiler, which is equivalent to raising the feed water temperature of the boiler, and reducing the energy consumption under the condition of a certain boiler output.
