FAQs on Thermal Power Plant Working Principle Video Lecture - Power Systems - Electrical Engineering (EE)

1. What is the working principle of a thermal power plant?
Ans. The working principle of a thermal power plant is based on the Rankine cycle. In this cycle, water is heated in a boiler using heat from the combustion of fuel. The heated water then generates steam, which drives a turbine to produce mechanical energy. The mechanical energy is then converted into electrical energy by a generator.
2. How does a thermal power plant generate electricity?
Ans. A thermal power plant generates electricity by converting heat energy into electrical energy. The heat is produced by burning fossil fuels, such as coal, oil, or natural gas, in a boiler. This heat is used to convert water into steam, which drives a turbine. The rotating turbine then powers a generator, where mechanical energy is transformed into electrical energy.
3. What are the main components of a thermal power plant?
Ans. The main components of a thermal power plant include a boiler, turbine, condenser, cooling tower, and generator. The boiler is responsible for heating water to produce steam. The steam then drives the turbine, which is connected to a generator. The condenser condenses the steam back into water, and the cooling tower cools the water before it is reused in the boiler.
4. How efficient is a thermal power plant?
Ans. The efficiency of a thermal power plant depends on various factors, such as the design, type of fuel used, and operating conditions. On average, thermal power plants have an efficiency of around 30-40%. This means that only about 30-40% of the heat energy produced by burning fuel is converted into electrical energy. The remaining energy is lost as waste heat.
5. What are the environmental impacts of a thermal power plant?
Ans. Thermal power plants have several environmental impacts. The combustion of fossil fuels releases greenhouse gases, such as carbon dioxide, which contribute to climate change. They also emit air pollutants, such as sulfur dioxide and nitrogen oxides, which cause air pollution and can harm human health. In addition, the cooling water used in thermal power plants can have adverse effects on aquatic ecosystems if not properly managed.
