The Condensate-Feedwater System is the light blue colored portion in the diagram. Water comes from condenser (represented by 3 pipes) to a Condensate pump (actually 3-4), then to Low Pressure Feedwater Heaters (usually 2 sets of 3-5 heaters), then to a Feedwater pump (usually 2-3), then to the High Pressure Feedwater Heaters (usually 2 sets of 1-2), then to the steam generators (for all types
The surface condenser is a critical component in the operation of a steam power plant. Condenser failures can result in forced outages and loss of generation capacity. TEi condensers represent an evolution of advanced technology, offering improved thermal efficiency and advanced mechanical design to reduce forced outages and increase availability.
Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle . The boiler takes in energy from some form of fuel such as coal , natural gas , or nuclear fuel to heat water into steam .
Typically most of nuclear power plants operates multi-stage condensing wet steam turbines (the high pressure stage runs on saturated steam). In these turbines the high-pressure stage receives steam (this steam is nearly saturated steam – x = 0.995 – point C at the figure) from a steam generator and exhaust it to moisture separator-reheater (point D).
Advantages of coal-fired power plant: It’s known that coal is the most widely used fuels for generating power and electricity around the world which means that the coal_fired power plant has many advantages as: It’s abundant and easy to burn. It doesn’t depend on the weather or existing climatic conditions for mining coal.
The efficiency of the steam turbine power plant depends on the type of fuel used in the boiler. The efficiency of coal-powered plants ranges from 32–42% depending on the pressure and temperature of the steam  .
Standby Losses: More than hydroelectric and nuclear power plants. Boiler flame has to be kept burning, so some amount of coal is used constantly, even when the turbine is not in operation. Cleanliness: Less clean. Smoke and ash are produced. Environmental Considerations: Air pollution occurs and leads to acid rain. Greenhouse gases are also produced.

Jun 08, 2019 · To enhance the thermal efficiency of the plant, the coal is used in the boiler in its pulverized form. In coal fired thermal power plant, steam is obtained in very high pressure inside the steam boiler by burning the pulverized coal. This steam is then super heated in the super heater to extreme high temperature.
The efficiency of nuclear plants is little different. On the steam turbine side they use the Rankine thermodynamic cycle with steam temperatures at saturated conditions. This gives a lower thermal cycle efficiency than the high temperature coal fired power plants. Thermal cycle efficiencies are in the range of 38 %.
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.

On the other hand treated water free from impurities and air is fed to the boiler drum where the combustion heat from the fuel is transferred to water to convert it into high pressure and temperature steam.
The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam. All but a small fraction of the world's primary energy comes from fuels, and about three-quarters of that fuel ends up going into a boiler (the remainder goes into internal combustion engines , which use the fuel differently).

Dec 30, 2018 · The basic principle of nuclear power station is same as conventional thermal power station. Only difference is that, instead of using heat generated due to coal combustion, here in nuclear power plant, heat generated due to nuclear fission is used to produce steam from water in the boiler. This steam is used to drive a steam turbine. This turbine is the prime mover of the alternator.
Dec 17, 2017 · There are two very common types of nuclear power plants in the West: Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs). In a BWR, the steam is produced inside the reactor vessel. Water is pumped through the hot nuclear fuel bundles, and boils (bulk boiling). Thus the “boiler” is the reactor pressure vessel in a BWR plant.
