Question

Draw a block diagram of a thermal power plant.

Answer 1

Here's a simple block diagram of a thermal power plant:

1. Boiler: This is where water is heated by burning fuel (like coal, oil, or gas) to produce steam.
   

1. Turbine: The steam produced in the boiler is directed to the turbine, where it spins the blades and generates mechanical power.
   

1. Generator: The turbine is connected to a generator that converts mechanical power into electrical power.
   

1. Condenser: After the steam passes through the turbine, it is cooled and condensed back into water in the condenser.
   

1. Cooling Tower: The hot water from the condenser is cooled in the cooling tower before being sent back to the boiler to be reheated.
   

1. Pump: A pump is used to circulate the water through the system, specifically to bring water from the condenser back to the boiler.
   

Here’s how it looks:

`
  +------------------+
  |    Boiler        |-----> Steam
  +------------------+   
            |
            v
  +-------------------+
  |     Turbine       |-----> Mechanical Energy
  +-------------------+
            |
            v
  +-------------------+
  |    Generator      |-----> Electrical Energy
  +-------------------+
            |
            v
  +-------------------+
  |    Condenser      |-----> Water
  +-------------------+
            |
            v
  +-------------------+
  | Cooling Tower     |-----> Cooled Water
  +-------------------+
            |
            v
  +-------------------+
  |     Pump          |-----> Water circulation
  +-------------------+
`

This is the basic flow of energy in a thermal power plant. The key parts are the boiler, turbine, generator, and condenser, with the cooling tower and pump completing the water cycle.
