1. Power Plant Instrumentation

2. What is Power Plant ? A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid.. A power plant is an industrial facility that generates electricity from primary energy.

3. Different types of Power Plant

4. Coal Based Thermal Power Plant A coal-fired power station or coal power plant is a thermal power station which burns coal to generate electricity

5. Working Principle The water is taken into the boiler from a water source. The boiler is heated with the help of coal. The increase in temperature helps in the transformation of water into steam. The steam generated in the boiler is sent through a steam turbine. The turbine has blades that rotate when high velocity steam flows across them. This rotation of turbine blades is used to generate electricity. A generator is connected to the steam turbine. When the turbine turns, electricity is generated and given as output by the generator, which is then supplied to the consumers through high-voltage power lines.

7. Main and auxiliary equipments Pulverizer : Pulverizer increases the coal combustion efiiciency of coal. Superheater : In a power plant, after the steam is conditioned by the drying equipment inside the steam drum, it is piped from the upper drum area into tubes inside an area of the furnace known as the super heater. Economizer : Economizer are mechanical devices intended to reduce energy consumption, or to perform another useful function like preheating a fluid. Reheator : Reheator added heat in the high-pressure steam. Condenser : Condenser is a device or unit used to condense a substance from its gaseous to its liquid state, typically by cooling it. Deaerator : A deaerator is a device that is widely used for the removal of air and other dissolved gases from the feed water to steam-generating boiler.

8. Main and auxiliary equipments : Boiler A boiler is a closed vessel in which water under pressure, is converted into steam. It is one of the major components of a thermal power plant always designed to absorb maximum amount of heat released in the process of combustion.

9. Main and auxiliary equipments : Turbine A steam turbine converts heat energy of steam into mechanical energy and drives the generator. It uses the principle that steam when issuing from a small opening attains a high velocity. This velocity attained during expansion depends on the initial and final heat content of the steam. This difference b/w initial and final heat content represents the heat energy converted into kinetic energy.

10. Main and auxiliary equipments : Generator Turbine and alternator are mechanical coupled with each other. Alternator convert mechanical energy of turbine into electrical energy. The electrical output from the alternator is delivered to the bus bar through transformer.

11. Components Of DAQ : Sensors Signal Conditioners Hardware Software

12. Function of DAQ Components Sensors : Sensors are devices that convert physical parameters into electrical signals that can be measured and recorded. They are used to measure physical parameters such as temperature, pressure, flow, and level
