What is the purpose of economizer in boiler?

What is the purpose of economizer in boiler?

Economizers are heat exchangers that transfer the heat in the flue gas to another medium‚ generally the boiler feed-water‚ although other streams are sometimes used such as make-up water. There are 2 types of economizers: non-condensing and condensing.

What is the main function of economizer?

As the name suggests, an economizer is a mechanical device used to economize the process of electrical power generation. Function of the economizer: Economizer works as a heat exchanger by preheating a fluid which as a result minimizes energy consumption.

Where is economiser used?

Explanation: Economiser is a device used to heat feed water by utilising the heat in the exhaust flue gases before leaving through the chimney. It improves the economy of the steam boiler.

What are economizers explain in detail?

An economizer is a mechanical device used to reduce energy consumption. Economizers recycle energy produced within a system or leverage environmental temperature differences to achieve efficiency improvements. Water-side economizers often operate during nightime to take advantage of cooler ambient temperatures.

Is economizer a heat exchanger?

An economizer is a type of heat exchanger that recovers heat from flue gasses to preheat fluids or puts it to use in another part of the production process. This recovery process saves on fuel consumption and costs, as well as it reduces the CO2 emission.

What is the main purpose of using an economizer in a boiler Mcq?

What is the main purpose of using an economizer in a boiler? Explanation: Economizer in boilers is used to heat fluids, upto a certain degree not beyond the boiling point of that fluid.

What is the function of economiser and air preheater?

Air Preheaters Similar to economisers, they are devices that transfer heat from one surface to another – but this time from fluid to air. The main objective is to increase the thermal efficiency of a boiler system by recovering the heat from the flue gas and using it to heat the air.

Where is economiser located in a boiler?

Economizers are installed in the exhaust gas flow from the boiler. They take heat from the flue gases which they transfer via extended surface elements to the feedwater immediately prior to the water entering the boiler.

What is the function of economizer in chiller?

An economizer is a relatively simple mechanical device with sophisticated controls. The economizer constantly monitors outdoor air temperature. It automatically draws outdoor air into the cooler/freezer whenever it is cold enough to substitute for compressor-generated cooling.

What is the function of economizer Mcq?

Explanation: Function of the economizer is to recover a portion of heat of the exhaust gases before the flue gases enter the chimney and discharged to the atmosphere.

What is the purpose of using economizer in the boiler Examveda?

Use of economiser in a boiler plant reduces the fuel consumption.

How economiser increases the efficiency of the boiler?

An economizer captures heat from the flue gas that would typically go to waste, and utilizes it to preheat the feedwater. By doing this, an economizer is able to increase thermal efficiency by decreasing the energy required to heat the water to steam.

What is the function of the economizer?

Economizer is used to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used in many purposes like boiler, power plant, heating, Refrigerating , ventilating, and air conditioning (HVAC). Economizer also called heat Exchanger.

What does an economizer do?

An economizer is a mechanical device used to reduce energy consumption. Economizers recycle energy produced within a system or leverage environmental temperature differences to achieve efficiency improvements.

How does an economizer work?

The economizer evaluates outside air temperature and even humidity levels. When the exterior air levels are appropriate, it uses the outside air to cool your building. HVAC economizers use logic controllers and sensors to get an accurate read on outside air quality.

What is a HVAC economizer?

An HVAC economizer works by drawing in the outdoor air. That is if the air is below the temperature setting and the humidity in the building is lower than the percentage set. This operation reduces the time frame in which your air conditioning unit is in operation.
