What is a boiler in a power plant?

What is a boiler in a power plant?

boiler, also called Steam Generator, apparatus designed to convert a liquid to vapour. In a conventional steam power plant, a boiler consists of a furnace in which fuel is burned, surfaces to transmit heat from the combustion products to the water, and a space where steam can form and collect.

Does a nuclear power plant have a boiler?

Nuclear Reactor The reactor is the heat source for the power plant, just like the boiler is for a coal plant. Uranium is the dominant nuclear fuel used in nuclear reactors, and its fission reactions are what produce the heat within a reactor.

Which boiler is used in nuclear power plant?

Steam generators are heat exchangers used to convert water into steam from heat produced in a nuclear reactor core. They are used in pressurized water reactors (PWR) between the primary and secondary coolant loops.

Whats a boiler do?

In simple terms, a boiler heats water to create steam and then disperses the steam to the rest of your home through pipes or radiators. How is the water heated in the first place? This typically happens by using natural gas or electricity to heat the entire tank.

What is boiler made of?

Materials. The pressure vessel of a boiler is usually made of steel (or alloy steel), or historically of wrought iron. Stainless steel, especially of the austenitic types, is not used in wetted parts of boilers due to corrosion and stress corrosion cracking.

Can a nuclear power plant explode like a nuclear bomb?

Truth: It is impossible for a reactor to explode like a nuclear weapon; these weapons contain very special materials in very particular configurations, neither of which are present in a nuclear reactor. Myth #3: Nuclear energy is bad for the environment.

How many boilers are there in power plant?

There are two types of boilers are used in sub critical, super critical and ultra-super critical coal fired thermal power plant: Pulverized coal-fired Boiler. Fluidized Bed combustion (FBC) boiler.

Why is coal used in boilers?

Using coal as fuel in order to create energy in the form of electricity and/or heat is very common in the world.

What are the components of boiler?

What are the Main Components of a Commercial Boiler

• Burner. The burner is the part of the boiler where air mixes with the fuel source and combusts.
• Combustion Chamber.
• Heat Exchanger.
• Controls.
• Supply Lines and Return Lines.
• Circulator Pump.
• Exhaust Stack.
• Conclusion.

Are boilers Gas or electric?

All modern boilers need a supply of electricity to operate. But electric boilers turn the electricity into heat – rather than burning fossil fuels. An electric boiler is an ideal for properties that aren’t connected to the gas network. Or for smaller homes and flats with a low demand for heating and hot water.

What is the purpose of a boiler in a power plant?

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.

How is thermal power supplied to a boiler?

Thermal power is supplied by a fuel to a boiler. 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.

How does a nuclear power plant boil water?

It depends on the nuclear power plant. 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).

What is the boiler in a BWR plant?

Thus the “boiler” is the reactor pressure vessel in a BWR plant. A BWR may be thought of as a fire tube boiler, except instead of having hot combustion gasses passing through boiler tubes, hot nuclear fuel pellets are inside the tubes. The steam generated is sent to the tubines driv…
