How does a condenser work in a coal power plant?
In power plants, condensers act as a heat-rejection engine when condensing steam into water. The volume collapse of that conversion (on the order of 1,700 times) causes a significant pressure change, creating a vacuum that pulls steam through the turbine.
What does a condenser do in a coal power plant?
How does a condenser work in a steam power plant?
What is condenser in power plant engineering?
Which type of condenser is used in thermal power plant?
How does a water-cooled condenser work?
A Water-Cooled Condenser is a heat exchanger that removes heat from refrigerant vapour and transfers it to the water running through it. Having the refrigerant vapour condensed on the outside of a tube achieves this. In doing so, the vapour condenses and gives up heat to the water running inside the tube.
How does an air cooled condenser work?
An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tubes. The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC.
Which method of air circulation is used in indoor cooling tower?
Air comes in from the sides of the tower and passes through the falling water. As the air passes through the water, heat is exchanged and some of the water evaporates. This heat and evaporated water flow out the top of the tower in the form of a fine cloud-like mist.
What is economizer in thermal power plant?
A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
What type of steam is produced in steam boiler?
A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water.
How boiler works in thermal power plant?
Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy.
How does a steam surface condenser work?
A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure.
How does a steam condenser work?
Steam Condenser Working Principle
A flow of cooling water is continuously circulating from the condenser inside a steam condenser to the cooling tower and the cooling tower to the condenser. When low-pressure exhaust steam leaves the turbine and passes through the condenser, it loses the heat and condenses into water.
Which type of condenser is used in window air conditioner?
Air cooled condenser is used in a window air conditioner.
What is ACC in power plants?
An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tubes.
What is natural convection condenser?
In natural convection air-cooled condenser the heat transfer from the condenser coils to the air is by natural convection. As the air comes in contact with the warm condenser tubes, it absorbs heat from the refrigerant and thus the temperature of air increases.
How do you cool a large building?

How long does it take to install a cooling tower?
Cooling tower is normally use to dispose heat from the return hot water by using air from the surrounding environment and discharge cooled water to equipment for cooling purposes. A single installation takes estimated 5-7 days per cooling tower to install.
How does a steam superheater work?
The saturated steam (at the boiling point) is separated from water in the steam drum area and is passed through the superheater tubes. The superheater heats steam above the saturation temperature for a particular boiler pressure. Superheater tubes have steam on one side and hot combustion gases on the other.
What is evaporator in boiler?
Evaporator is a boiler component that functions to convert water into saturated steam. It is able to change the whole or part of a solvent from a solution in the form of liquid to steam. So that it only leaves a denser or thick solution. The process that occurs in the evaporator is called evaporation.
How do you make superheated steam?
Superheated steam can be generated by taking, for example, steam drawn from a boiler. It is then passed through a separate heating device, called a superheater, to transfer additional energy into the steam through direct contact or radiation.
