What is meant by economizer?
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.
What is economiser function?
Economizers (US and Oxford spelling), or economisers (UK), 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.
What is economiser in thermal power plant?
An economiser is a mechanical device which is used as a heat exchanger by preheating a fluid to reduce energy consumption. The recovered heat is in turn used to preheat the boiler feed water, that will eventually be converted to super-heated steam.
How many types of economizer are there?
2 types
There are 2 types of economizers: non-condensing and condensing.
What is economizer in ship?
Economiser is a type of boiler which is installed in the exhaust passage of the main engine and where the exhaust heat energy is utilised to generate steam from fresh water. Steam generation on ships is done using boilers and economisers which are provided in all ships.
What is chiller economizer?
An economizer is a type of sub-cooler that uses part of the total refrigerant flow from the condenser to cool the rest of the refrigerant flow (see Figure 10.13). The cold gas from the economizer can also be used to provide extra cooling for the compressor.
How many types of economizers are there?
What is evaporator in power plant?
a heat-exchange device for evaporating liquids. In thermal power engineering, the evaporator is used to produce a distillate that compensates for losses of condensate in steam power plants. The steam produced in such evaporators may be used both to compensate for losses of condensate and to provide heat. …
What is the purpose of an economizer on a rooftop unit?
In a nutshell, an economizer is a mechanical vent attached to a roof top unit (RTU) that opens to draw-in outside air for cooling a building when the outside air temperature is cool and dry enough.
What is an economizer in a chiller?
What is auxiliary boiler in ship?
A steam generator on a ship is an auxiliary boiler which draws high-pressure superheated steam from the vessel’s propulsion system to generate low pressure saturated steam. …
What is the meaning of the word economizer?
Word forms: (regular plural) economizers. noun. (Mechanical engineering: Energy, thermodynamics and heat transfer) The economizer of a boiler is the part where heat is taken out of flue gas.
What does an economizer do in a boiler?
An economizer, which removes heat from the flue gases about to go up the chimney, must be appropriate to the conditions in the plant. The economizer is the place in a boiler where heat is taken out of flue gas.
Where is the economizer located in a plant?
The economizer is located between the firebox and the stack, and the hot flue gases pass through it as they move out of the firebox and into the stack. An economizer, which removes heat from the flue gases about to go up the chimney, must be appropriate to the conditions in the plant.
