Every ATAG boiler carries a 10 years warranty as standard with options up to 14 years. Some years ago, ATAG's design engineers realised there was untapped residual heat left in the waste flue gases when the boiler was being used for hot water. So they set upon harnessing the wasted energy and the ATAG Economiser Plus was born.Get Price

Answer (1 of 8): In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are …Get Price
Mar 03, 2021 · A boiler economizer or flue gas heat recovery unit is a heat exchanger that is installed on the stack of a boiler. It is designed to recover heat that would otherwise be wasted. Economizers can be installed during a new boiler installation or retrofit on an existing system.Get Price
The economizer is the last water heat transfer unit upstream of the air heater. Economizer is located in the second pass of the boiler. Types of economizer. Economizer can be classified on the basis of economizer surface, and boiler efficiency. On the basis of economizer surface:-Bare tube coiled economizer are more common.Get Price
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. Applications of EconomizerGet Price
Economizers (as well as air heaters) perform a key function in providing high overall boiler thermal efficiency by recovering low level (i.e., low temperature) energy from the flue gas.For each 40F (22C) that the flue gas is cooled by an economizer or air heater in a conventional boiler with air as the oxidant and normal excess air, the overall boiler efficiency typically increases by Get Price
Hence, the economiser in thermal power plants, is used to economize the process of electrical power generation, as the name of the device is suggestive of. The recovered heat is in turn used to preheat the boiler feed water, that will eventually be converted to super-heated steam. Thus, saving on fuel consumption and economising the process to Get Price
Nov 27, 2020 · The economizer is the heating surface in the tail flue of the boiler that heats the boiler feed water into saturated water under the pressure of the steam drum. Because it absorbs relatively low temperature flue gas, it reduces the flue gas exhaust temperature and saves It improves energy and efficiency, so it is called an economizer.Get Price
Feb 24, 2012 · Boiler economizer is a device that uses a portion this remained energy of the flue gas to heat up inlet water (feed water) to the boiler. Since the heat energy is given to the water before it gets fed to the boiler, the requirement of fuel for producing steam is optimized. Because of that, we call this device as an economizer.Get Price

Economizers are used to recover the useful heat in exhaust or flue gas before it is released into the atmosphere and transfer it to the steam production cycle. This increases the overall boiler thermal efficiency, resulting in more steam with less fuel. Boiler efficiency increases by approximately 1% for every 40°F the flue gas is cooled.Get Price
A stack economizer is a heat exchanger that transfers heat from flue gases to the boiler feedwater. The boiler feedwater is piped through finned tubes that are placed in the path of the hot flue gases. Economizers are usually located directly above the stack outlet of the boiler.Get Price
