how does a cooling tower work in power plant

This water then circulates through the plants condenser tubes absorbs heat from the steam and travels back to the cooling tower. Dry-cooling systems use air instead of water to cool the steam exiting a turbine.

First lets review the purpose of a cooling tower.

. Air comes in from the sides of the tower and passes through the falling water. How does a cooling tower work. Air enters the lower portion of the tower and contacts the water in a counter-current manner to help maximize heat transfer.

Cooling towers work on the principle of psychometric properties of air. Wet cooling towers or evaporative cooling towers operate on the principle of evaporative cooling. Some of the water evaporates.

For any efficient power plant to function at its optimum level cooling towers form an essential unit. A part of the cooling water evaporates taking in Latent Heat from the water reducing its temeprature. Steam than goes to turbine unit A turbine is a rotary engine which rotates with flow energy of steam.

All thermoelectric power plants that use heat to make steam to drive a turbine generator need a system to cool water. The cooled water collects in a sump for return to the heat exchangers. Large cooling towers like those at nuclear power plants rely on a natural draft or flow of air through the cooling tower.

This is typically in the form of hot water that remains after the steam energy has been used to rotate the steam turbines and then condensed back to liquid state. The rest is then sent back to the condenser in the power plant. A properly sized Cooling tower can cool the incoming water to temperatures up to 3 C more than the ambient wet bulb temperature.

The majority including Harris and Brunswick use a once-through cooling system where water is drawn from a lake river or reservoir. Cooling Tower Working in Thermal Power Plant In thermal power plant water is heated in a boiler to make steam. The cooling tower is widely used in power generation plants.

A cooling tower is designed to remove heat from a building or facility by spraying water down through the tower to exchange heat into the inside of the building. Most cooling towers use an electrical fan motor to create an air draft or airflow through the cooling tower. Water is pumped from the lake into the cooling tower basin.

Cooling towers are a special type of heat exchanger that allows water and air to come in contact with each other to lower the temperature of the hot water. All power plants create heat as a byproduct of generating electricity. This type of cooling tower is called an Induced or Force Draft cooling tower.

However this is only effective on certain very large cooling towers. They are used to transfer heat and cool the water. The water is then sprayed through the hollow core of the cooling tower onto a grid in the center of the tower.

Most commonly wet-recirculating systems use cooling towers to expose water to ambient air.
