A 15 kW steam turbine is a small-scale turbine designed to generate 15 kilowatts of power using steam as the working fluid. Steam turbines convert thermal energy from high-pressure steam into mechanical energy, which can then be used to drive a generator for electricity generation or perform other mechanical work. Here are some key points related to a 15 kW steam turbine

15kw Steam Turbine

A steam turbine is a device that converts the thermal energy of steam into mechanical energy, which is then used to generate electricity or perform other types of work. Steam turbines are widely used in power plants, industrial facilities, and marine applications.

Here’s a basic overview of how a steam turbine works:

  1. Steam Generation: Steam is produced by boiling water using a heat source, such as burning coal, natural gas, or using nuclear reactions. The steam can also be generated in other ways, like geothermal energy or solar power.
  2. Expansion of Steam: The high-pressure steam produced in the boiler is directed to the blades of the turbine. As the steam flows over the turbine blades, it expands and loses its high-pressure energy. This causes the blades to rotate.
  3. Rotor Rotation: The rotating blades are attached to a shaft known as the rotor. As the blades turn, the rotor also rotates.
  4. Mechanical Work: The rotating shaft is connected to a generator, which converts the mechanical energy of the rotating shaft into electrical energy. This is how electricity is generated in power plants.
  5. Exhaust: After the steam has passed through the turbine, it exits at a lower pressure and temperature. This low-pressure steam is then condensed back into water and returned to the boiler to be reheated and used again in a continuous cycle.

There are different types of steam turbines, including impulse turbines and reaction turbines, each with its own set of applications and operational characteristics. Impulse turbines are driven by the force of the steam’s impact on the turbine blades, while reaction turbines are driven by the reactive force of the steam as it changes direction.

Steam turbines have been a critical component in power generation for many years and continue to play a significant role in producing electricity worldwide. They are known for their efficiency, reliability, and versatility in various industrial processes.

Types of Steam Turbines

  1. Impulse Turbines:
