Why is an economiser used in a boiler? - Quora

Sep 07, 2015 · In industrial 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.

ENGINEERING MANUAL Industrial Boilers

Boilers, both hot water and steam, are the basic form of heating in many commercial and industrial facilities. Applications range from HVAC heating to hot water heating for manufacturing processes and account for significant energy use and costs. Flue gas economizers can increase boiler thermal efficiency by recovering exhaust gas waste heat.

Economiser in Thermal Power Plant - Electrical4U

Economizers in landbased boilers. An economiser used with a boiler located on land uses the boiler's waste gases. The water circulated over the economiser is normally supplied by the main feed pump, but can also be fitted with its own circulation pump. The chimney will also include a bypass to allow waste gases to pass around the heat exchanger.

Boiler Economiser - Industrial Steam Boiler Manufacturer

Apr 14, 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.

BOILER ECONOMISER - Thermal Power Tech

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.".

Economizer - Wikipedia

The cylindrical economizers are cost effective designs that fit into the stack, thus requiring no expensive transitions. Sootblowers, when required, are an integral part of the design. The rectangular designs are used for the larger industrial watertube boilers but are adaptable for sizes from as low as 15,000 PPH to 500,000 PPH and greater.

Effect of Economizer on Efficiency of the Fire Tube Steam

The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be
