Power Plant Boiler Layout

Components or parts of thermal power plant.

Power plant boiler layout. Wet steam or unsaturated steam it is a mixture which contain both water vapor and liquid water droplets most of the best boiler discharge steam containing 3 to 5. The water present in the boiler is heated up by means of a furnace and as the density of steam is less. Though each plant is unique in itself in terms of specific features and functionalities still there is a broad outline to which all thermal power plants confirm to and in this article we will study about the general layout of a typical power plant. A boiler or steam generator is a device used to create steam by applying heat energy to water although the definitions are somewhat flexible it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure 7 2 000 kpa or 1 290 psi but at pressures above this it is more usual to speak of a steam generator.

Boiler in a power plant has two functions. Heat energy can be get from boiler by burning oil hfo hco etc and coil. The customer s preliminary specifications usually contain the following items. The combustion system converts energy in coal to heat.

The above shown line diagram is the basic layout of the thermal power plant electric generation process. Working of a power plant boiler. Layout of steam power plant construction. Saturation temperature it is the temperature for a corresponding saturation pressure at which a liquid boil into its vapor phase.

Generally bituminous coal or brown coal is used as fuel. This is game of four energies. Main thermal power plant based on phenomena of converting heat energy in to electrical energy. A simplified layout of a thermal power station is shown below.

The above are the major water and steam circuit items in a boiler and are collectively called the pressure parts. This post is part of the series. This boiler coverts the water into steam. Other equipment referenced and called balance of plant include an electrostatic precipitator used for taking ash out of the gas stream and cooling towers to cool the steam after passing through the turbine and so be able to reuse the.

Normally a boiler is designed to suit user s requirements. Therefore the boiler design starts with the basic specifications stated by user or customer. In a coal based thermal power plant coal is transported from coal mines to the generating station. This steam expansion in turbine created mechanical power which in turn drives big alternator couples.

The biomass boiler and turbine are the key elements in making an efficient and reliable power plant. Steam penetration maximum continuous rating mcr steam pressure. Thermal power plant layout. The main parts of thermal power plant.

Before feeding to the furnace the coal is to be converted into the pulverized form and after.
