Why is an economiser used in a boiler? - Quora

A heating and cooling specialist may provide advice on the installation and cost savings of a boiler economizer. Boilers operate by heating water to make steam, and using that steam for heat or energy generation. For the most part, a boiler is fairly efficient, but there is some heat loss when the byproducts of combustion are vented.

How Boiler Economizers Reduce Energy Consumption | Miura

Mar 03, 2021 · Summary. Economizers lower the consumption of fuel for a given steam demand. They also reduce thermal stress in the boiler and add heat transfer surface area to the boiler system. "By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years.".

How To Calculate The True Cost of Steam

Steam boilers use economizers to greatly improve efficiency as the system heats water for steam. The first economizer, patented in 1845, was used to improve the efficiency of boilers used in steam engines for mills and factories. By the 20th century, almost all steam engine boilers included economizers as a standard feature. Here, we will

Industrial Boiler - an overview | ScienceDirect Topics

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 hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency.
