Boiler Economisers can be classified in various ways depending upon 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.

14-04-2017· In a boiler system, an economizer captures the heat of the flue gas and transfers it to the feed water. The process is simple. As the flue gas exits the boiler, it enters an economizer with finned tubes. The finned tubes absorb the heat and raises the temperature of the boiler feed water, lowering the needed energy input.

Click to view on 5:1530-04-2018· Today on the Boiling Point, WARE Boiler University Instructor Jude Wolf talks about what an economizer can do on a steam boiler. Getting efficiency in an existing boiler room can be difficult and

An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost. If this is a significant number to you, then you should consider adding an economizer.

04-03-2020· Working Principle of Economizer As shown in the figure above, the flue gases coming out of the steam boiler furnace carry a lot of heat. Function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler.

· PDF fileBoiler tube failure is a major cause of concern to plant engineers as it leads to many forced outages of the power plants. The cause of failure may be associated with waterside corrosion, fire side corrosion, overheating, stress rupture, erosion or fatigue.

  • OverviewThe economizer is made up of a bunch of horizontal water tubes usually located in the back pass or second pass (after the primary superheaters and reheaters) of the boiler through which the feedwater enters the boiler to absorb residual heat from the exhaust flue gas and transfer it to the steam production cycle.

Economizer (heat exchanger) is the boiler accessory used to recover the heat of flue gas that leaving the boiler by heating feed water. The efficiency of a boiler can be increased with an economizer. 60C rise in feed water temperature with the help of economizer can save up to 1% of fuel.
