Mar 18, 2017 · Cooling tower: In thermal power plant, ordinary water pumped from river, canal or pond is used to cool the exhaust steam from the turbine in the condenser. This process requires large amount of water. So to reuse that water, cooling towers are used to cool the heated water coming out from condenser.
Robust design for flexible operation. Designed to handle turbine and steam generator overloads and variations in cooling water temperature. It is resistant to both impingement erosion and tube vibration.
Most of that water is used for cooling. Power plants boil water to produce steam, which is used to spin the turbines that generate electricity. Then, staggering volumes of water are withdrawn from nearby rivers, lakes, and oceans to cool the steam back into water so it can be used to produce more electricity.
Cooling arrangement: In order to improve the efficiency of the steam power plant, the steam exhausted from the turbine is condensed by means of a condenser. Water is drawn from a natural source of supply such as a river, canal or lake and is circulated through the condenser.The circulating water takes up the heat of the exhausted steam and itself becomes hot.
The superheated steam generated at high pressure in the boiler (Fig. 5.3, point 1) is adiabatically expanded in the turbine by changing its pressure from P BOILER to the P CONDENSER, generating power.
The steam generating boiler has to produce steam at the high purity, pressure and temperature required for the steam turbine that drives the electrical generator. Geothermal plants do not need boilers because they use naturally occurring steam sources. Heat exchangers may be used where the geothermal steam is very corrosive or contains excessive suspended solids.
Large Steam System Condensers: Heat Exchanger Knowledge | Heat Exchanger Companies Suppliers. The steam condenser, shown in Figure 9 below, is a major component of the steam cycle in power generation facilities. It is a closed space into which the steam exits the turbine and is forced to give up its latent heat of vaporization.

Recirculating systems can consist of a cooling tower or a cooling pond with both using ambient air to draw energy out of the cooling water that was used to condense the steam. At a cooling tower, the process of lowering the cooling water temperature produces the plumes of evaporation often associated with power plants.
Evaporative steam condensing systems combine an open cooling tower with a steam condenser into one common unit. According to David Hutton, Baltimore Aircoil Company, the cost of installing
Dec 31, 2011 · In a jet condenser, steam escapes with cooling water and this mixture inhabits recovery of condensate to be reused as boiler feed water. In this case, the cooling water should be fresh and free from harmful impurities. However, with moderate size turbine units the jet condensers can be used if enough supply of good quality cooling water is available. Steam surface condensers are the most commonly used condensers in modern power plants.
COOLING TOWERS AND WATER PONDS: Water cooling is very important for working of thermal power plant. Condensation process involves huge quantity of water to condense the hot steam. Cooling tower provides cooling to the water which is reused in the power generation process.
b) Steam Power Plants A basic steam power plant consists of four interconnected components, typically as shown in the figure below. These include a steam turbine to produce mechanical shaft power, a condenser which uses external cooling water to condense the steam to liquid water, a feedwater pump to pump the liquid to a high pressure, and a boiler which is externally heated to boil the water to superheated steam.
The biomass boiler and turbine are the key elements in making an efficient and reliable power plant. Other equipment referenced (and called balance of plant) include an electrostatic precipitator (used for taking ash out of the gas stream), and cooling towers to cool the steam after passing through the turbine and so be able to reuse the specially processed water.
The above are the brief of the main equipment required for the proper combustion of coal in a large power plant boiler. WORKING OF A POWER PLANT BOILER. Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat. Water and steam system converts the heat to steam at high pressures and temperatures.
Aug 09, 2016 · In the steam power plant the pulverised coal is fed into the boiler and it is burnt in the furnace. The water present in the boiler drum changes to high pressure steam. From the boiler the high pressure steam passed to the super heater where it is again heated upto its dryness.
The heat input required by the boiler to produce the required steam is only 1,149.1 Btu/lbm (1,474.1 – 325.0), as the feedwater temperature is much warmer. Thus, the efficiency of this system is

8 In topping-cycle systems, the energy in fuel is first used to generate electricity. Waste heat from the prime mover is then recovered and used for process heating or cooling applications. Figure 2.1 illustrates energy flow in a topping cycle.
Thermal Efficiency Improvement – Rankine Cycle. The process of superheating is the only way to increase the peak temperature of the Rankine cycle (and to increase efficiency) without increasing the boiler pressure. This requires the addition of another type of heat exchanger called a superheater, which produces the superheated steam.
