Meaning of High Pressure Boilers 2. Types of High Pressure Boilers 3. Characteristics 4. Advantages. Meaning of High Pressure Boilers: These are used to increase the efficiency of the plant. These are developed because of rising cost of fuel and restrictions on air pollution. Modern power generation plants generally use high pressure boilers.
This was the basic working principle of a thermal power station and its typical components. A practical thermal plant possess more complicated design and multiple stages of turbine such as High Pressure Turbine (HPT), Intermediate Pressure Turbine (IPT) and Low Pressure Turbine (LPT). Advantages and Disadvantages of a Thermal Power Plant.
Therefore, water- tube boilers are generally preferred for high pressure and high output, whereas, shell boilers for low pressure and low output. The modern high pressure boilers employed for power generation are for steam capacities 30 to 650 tonnes/h and above with a pressure up to 160 bar and maximum steam temperature of about 540°C.

Dec 17, 2016· Modern thermal power plant 1. Introduction A steam power plant / thermal power plant is using steam as working fluid. A thermal power station is a power plant in which the prime mover is steam driven. Steam is produced in a boiler using coal as fuel and is used to drive the prime mover, namely the steam turbine. Water is heated, turns into steam & spins a steam turbine which drives an
Sep 17, 2017· A simple steam plant works on Rankine cycle. In the first step, water is feed into a boiler at a very high pressure by BFP (boiler feed pump). This high pressurized water is heated into a boiler which converts it into high pressurized super heated steam. This high energized steam passes through steam turbine (a mechanical device which converts flow energy of fluid into mechanical energy) and
in thermal power plants, which provides high pressure boiler in modern thermal power plant can meet boiler has the advantages of power . UNIT 2 STEAM POWER PLANT Steam Power Plant Increasing the boiler pressure (Increases T high and it is commonly used in modern steam power plants. The
Advantages And Disadvantages Of A Thermal Power Plant Advantages: withstand high pressure. • The boiler drum contains both steam and water, the former being trapped from the top of • In addition to super heater modern boiler has reheater also. The function of the reaheater is
A boiler is called a high pressure boiler when it operates with a steam pressure above 80 bar. The high-pressure boilers are widely used for power generation in thermal power plants. In high-pressure boiler if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases. The feed
Coal and ash handling arrangement. In a coal-based thermal power plant, coal is transported from …The inevitable effect of use of higher pressure in power plants is that, the saturation line is reached which is highly undesirable. There is heavy blade erosion due to the impact of the water particles carried with the steam. Therefore, the reheating is essential in high pressure modern thermal power plants to increase the lifetime of the plant.

Thermal Power Station process flowchart and diagram. The fuel is transported from mines via trains to the fuel storage facility in a power plant. 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 crushers.The fuel is then fed to the boiler generating a large amount of combustion heat.
(c) The generation cost is high as compared to a hydro-electric plant. (d) The life of a thermal power plant is less as compared to a hydro-electric power plant. Layout of a Hydro Power Plant: Figure 5.3 shows the layout of a hydro power plant. Water from the bottom of dam is carried to turbine by a large diameter tube known as penstock.
Oct 27, 2016· A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
The Role of Thermal Power Plant in the Modern Power Generation Scenario. The development of thermal power plant in any country depends upon the available resources in that country. The hydro-power plant totally depends on the natural availability of the site and the hydrological cycle. The new sites cannot be created manually for hydropower plants.
INTRODUCTION OF THERMAL POWER PLANT. Thermal power plant or steam power plant is a generating station which converts heat energy of fossile fuels into electrical energy.Generally bituminous,brown or peat type coal are used as the fuel of coal basesd thermal power plant.. In a thermal power palnt, coal is burnt in a big boiler which produces steam at high pressure and temperature.
