Boiler diagram boiler thermal power plant. In a thermal power plant coal is coming from coal storage and burnt in the boilerit converts water into steam. Turbine which produces mechanical power driving the alternator coupled to the turbine. A detailed analysis of typical power plant boiler is illustrated in this video with help of animation. Coal creates required heat energy by combustion in the furnace.
The fuel is transported from mines via trains to the fuel storage facility in a power plant. Water and steam system converts the heat to steam at high. Technically boiler systems do not remove or add humidity with the exception of cast iron boilers. Water is required in a thermal power plant inside a boiler to produce steam.
Boiler feed pump take the suction from the deaerator and send the water to the boiler in starting of the boiler light up we take the boiler feed pump into manual mode after starting boiler steam. Coal is fuel here because we are going to draw the flow diagram of a coal thermal power generating plants. In steam power plants the heat of combustion of fossil fuels is utilized by the boilers. Indian coals are classified as a g grade coals.
Boiler in a power plant has two functions. Boiler feed pump for power plant operation. Different parts of. Working of a power plant boiler.
Although the definitions are somewhat flexible it can be said that older. Today we discuss about the boiler feed pump its a very critical component each and every power plant industry. This steam is expanded in the prime mover ie. Thermal power plant operation.
This post is part of the series. Here working and construction details of water tube boiler is explained. The above are the major water and steam circuit items in a boiler and are collectively called the pressure parts. A low efficiency boiler however will utilize indoor air to make the necessary combustion flame.
Types of thermal energy. The working principle of thermal power plant operation depends on rankin cycle. Natural gas is frequently burned in gas turbines as well as boilersthe waste heat from a gas turbine in the form of hot exhaust gas can be used to raise steam by passing this gas through a heat recovery steam. The combustion system converts energy in coal to heat.
Thermal power station process flowchart and diagram. We can say it is a heart of boiler. Air is supplied to the furnace to accelerate combustion rate of the coal and to continue the flow of flue gases inside the heating system. Boiler working animation a boiler or steam generator is a device used to create steam by applying heat energy to water.
The fuel transported to the plant is generally bigger in particle size and before it is fed to the boiler furnace it is broken down into smaller pieces using crushersthe fuel is then fed to the boiler generating a large amount of combustion heat.
