Economizers, or economisers, are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used for other purposes as well. Boiler, power plant, heating, Refrigeration, ventilating, and air conditioning (HVAC) uses are discussed in this article. In simple terms, an economizer is a heat exchanger. Economizer is composed of boiler tubes, inlet header, outlet header, pipe clamp or tube clip, bend or elbow, and other...

Thermal Power Plant Boiler Pressure Parts Economizer is part of the heating area of boiler, to heat the feed water into saturated water inside the flue ducting, due to its absorption of low temperature flue gas heat, the feedwater economizer reduces the exhaust temperature of flue gas, save the energy, improve the efficiency, so called as economizer. Economizer steel tube type is without pressure limit, can be used as a boiling type, generally made by the outer diameter of 32 ~ 51 mm carbon...

In steam power plants Boiler Accessories Economizer captures the waste heat from boiler stack gases (flue gases) and transfers it to the boiler feed water. Air-side economizers HVAC (Heating, Ventilation, and Air Condition) can save energy in buildings by using cool outside air as a means of cooling the indoor space. Refrigeration: This is commonly used in industrial refrigeration where vapor compression refrigeration is essential. Systems with economizers aim to produce part of the...

In a steam boiler,water stack economizer is a heat exchanger device that heats up fluids or recovers residual heat from the combustion product i.e. flue gases in a thermal power plant before being released through the chimney. Flue gases are the combustion exhaust gases produced at power plants consist of mostly nitrogen, carbon dioxide, water vapor, soot carbon monoxide etc. Hence, the economizer in thermal power plants is used to economize the process of electrical power generation, as the...

Flue gases from large boilers are typically 450 – 650°F. Gas Economizers recover some of this heat for pre-heating water. The water is most often used for boiler make-up water or some other need that coincides with boiler operation. Gas Economizers should be considered as an efficiency measure when large amounts of make-up water are used (IE: not all condensate is returned to the boiler or large amounts of live steam are used in the process so there is no condensate to return) or there is a...

Superheaters and reheaters are used where only dry steam is required in a process/machines such as Turbines. Any moisture content in a steam in such cases happens to degrade or corrode the machine thereby affecting its average operating life. So, superheater converts low-quality steam to high quality for end users.Superheaters can be used in a steam engine where absolute dry steam is needed to prevent wear and tear of engine parts.There are following types of superheaters: radiant superheater,...

The Boiler Replacement Steam Superheater is a coil type heat exchanger which is used to produce superheated steam or to convert the wet steam to drysteam, generated by a boiler. It is different from a boiler in a way that, boiler utilizes both sensible heat as well as latentheat to convert water into steam while superheater utilizes only sensible heat to superheat the steam in order to increase itsenthalpy.It is composed of superheater tubes or reheater tubes, tube/pipe support, elbow pipe,etc....
