The boiler generates steam at high pressure and high temperature. The steam turbine converts the heat energy of steam into mechanical energy. The generator then converts the mechanical energy into electric power.
Which boiler is used in thermal 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.
What is the working principle of boiler?
Working Principle of a Boiler
Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel, the point where the heat transfer takes place between the steam and water. Thus, the boiler’s basic principle is to convert water into steam with heat energy.
What are the 3 types of boilers?
There are three main types of boilers you can install into your home: combi boilers, heat only (regular boilers) and system boilers.
What is boiler types of boiler?
There are mainly two types of boiler – water tube boiler and fire tube boiler. In fire tube boiler, there are numbers of tubes through which hot gases are passed and water surrounds these tubes. In water tube boiler the water is heated inside tubes and hot gasses surround these tubes. …
How does a supercritical boiler work?
Rather than boiling water to produce steam and then using that steam to turn a plant’s turbine, a supercritical boiler operates at such high pressure (3,208 psi/221.2 bar or above) that the fluid matrix in it ceases to be liquid or gas. … This supercritical fluid turns the turbine that generates electricity.
Which generator is used in thermal power plant?
Steam turbine-driven generators are commonly used in solar thermal electric power plants, coal, geothermal, nuclear, waste incineration plants, and natural gas power plants. They are also used extensively in cement, sugar, steel, paper, chemicals, and other industries.
Which coal is used in thermal power plant?
Coal bottom ash
Coal is the dominating fuel source used in thermal power plants for generation of electricity.
What are the two types of boiler?
When we think about boilers, there are a two types that typically come to mind; firetube, or scotch marine, and watertube boilers. These types of boilers can be classified as hot water, steam, high pressure, and low pressure.
What are the main parts of boiler?
The key elements of a boiler include the burner, combustion chamber, heat exchanger, exhaust stack, and controls. Boiler accessories including the flue gas economizer are also commonly used as an effective method to recover heat from a boiler.
What is a green boiler?
Green boilers are designed to rectify the wastage of previous boiler designs; whereas traditional heating systems have two tanks, eco-friendly boiler models are designed either to integrate them into one tank or keep the separate storage as close to the heating system as possible.
What is boiler heat exchanger?
A heat exchanger does precisely what its name describes – it allows heat to be exchanged between two fluids or substances, usually water or gas, without letting the substances mix together. Within the heat exchanger is a long, coiled pipe.
What type of boiler is best?
Pros: Condensing boilers are the best types of boilers for the environment. Condensing boilers allow you to heat your home in a way that’s much more efficient, and that means you’ll save money on your heating bills and save energy as well.
