A boiler is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy.
Which boiler is used in power plant?
Steam boilers are used where steam and hot steam is needed. Hence, steam boilers are used as generators to produce electricity in the energy business.
What is the function of boiler in steam power plant?
A steam power plant consists of a boiler, steam turbine and generator, and other auxiliaries. 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.
What is boiler in power plant engineering?
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.
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 are the main parts of a boiler?

What is boiler PDF?
A steam boiler is a closed vessel, generally made of steel, in which water is heated by some source of heat produced by combustion of fuel and ultimately to generate steam. The steam produced may be supplied at low pressure for industrial process work in cotton mills, sugar industries etc.
Can a boiler produce electricity?
The SmartWatt boiler has a power plant inside. The unit not only gives off heat, but it can generate electricity for less money and with fewer emissions than buying juice from the grid, its creators say. … Cogeneration, or combined heat and power, has been done before.
What is a superheater in boiler?
A superheater is a device used to convert saturated steam or wet steam into superheated steam or dry steam. Superheated steam is used in steam turbines for electricity generation, steam engines, and in processes such as steam reforming.
What are the disadvantages of boiler?
Disadvantages Of System Boilers
- Take Up Space – Although system boilers don’t need a cold water tank they still take up more room than a combi boiler. …
- Limited Hot Water – The amount of hot water you have is limited to how much water your hot water cylinder is.
Is boiler heat cheaper than forced air?
Installing a forced-air system is a lot more inexpensive than a hot water boiler system. Considering the comparable size and efficiency, the boiler itself and its installation tend to be 2-3 times more costly than a home furnace.
Where is boiler used?
Where are Boilers Used? Anywhere you are creating heat and/or steam, you will probably find a boiler. ABMA members produce large boilers for the commercial, industrial, utility sector and more. Boiler systems are used to create pulp & paper, generate electricity and process foods.
What is boiler technology?
Boilers are used to turn the energy originating from a combustion process to usable heat and/or power. … Two main boiler technologies are currently available on the market: watertube and firetube boilers. In watertube boilers, the water is heated by circulating in tubes around which the hot combustion gases flow.
What is boiler PPT?
3. PRINCIPLE OF OPERATION The boiler is essentially a closed vessel inside which water is stored. … These hot gasses come in contact with water vessel where the heat of these hot gases transfer to the water and consequently steam is produced in the boiler. This steam is piped to the turbine of thermal power plant.
