Thermal Power Plant - How It Work
A Thermal power plant is a type of power plant that generates electricity by using heat to produce steam, which drives a turbine connected to a generator.
Thermal power plants can use a variety of fuels, such as coal, natural gas, oil, and biomass. They can also use renewable energy sources, such as solar thermal or geothermal heat, to produce electricity.
How Does a Thermal Power Plant Work
Thermal Power Plant, the working principle is almost the same as the Steam Power Plant. In a steam power plant that is made using a boiler. While the thermal power plant uses steam from the reservoir.
1. The steam supplied from the reservoir enters the steam receiving header which functions as a steam collecting medium, as well as a pressure stabilizer. So when there is excess pressure, the steam will be discharged through the vent structure.
2. From the steam receiving header the steam then flows to the separator. This separator functions to separate steam from solid substances or foreign objects, such as; heavy particles (sodium, potassium, calcium, silica, boranes, ammonia, fluorine and others)
3. The steam entering the separator will rotate due to the difference in specific gravity, so the particles will fall down to be accommodated by the collector dust, while the clean steam will exit through the pipe at the top of the separator.
4. The steam then flows into the demister which functions as a separator for moisture contained in the steam, so that only clean steam will enter the turbine.
5. After leaving the demister, it is certain that the steam produced is clean steam which is used to rotate the turbine which is on the same axis as the generator, so that the geothermal power plant produces electricity.
6. The remaining steam from the turbine is then condensed in the condenser. NCG (Non condensable gas), or gas that cannot be condensed into the condenser is sucked by the first ejector then enters the intercondenser as a cooling medium and is then discharged into the atmosphere through the cooling tower.
7. As the name implies, the cooling tower functions as a water cooler, the water that is pumped from the condenser is channeled to the tub located above the cooling tower. The bath then separates the water into fine droplets and is cooled by direct contact with the cooling air.
8. After the cooling process occurs, the water will descend due to gravity, and go to the water reservoir located at the bottom. From here the water is circulated back into the condenser as a cooling medium. The overflow from the reservoir is used for reinjection pump purposes.
