how does a gas turbine work
How does a gas turbine work?! Solar turbines convert steam into mechanical energy to drive a steam generator to produce electricity. In advanced systems, tracking systems are connected to focus solar radiation on the receiver as the sun’s position in the sky changes throughout the day.
A gas turbine or gas turbine engine is a type of continuous-flow internal combustion engine
Solar thermal energy
Solar energy generation systems are designed to collect sunlight to provide the heat needed to produce electrical energy.
Two main components of a solar energy collector
- Reflective mirrors to absorb solar radiation
- Receivers to concentrate sunlight
Some solar power plants have a thermal energy storage system to absorb and store excess heat energy during the day, so that the excess heat absorbed by them can be used to generate electrical energy in the evenings and nights.
How does a gas turbine work? A steam turbine is a type of steam engine that extracts thermal energy and converts it into rotational motion that is used to drive an electric generator.
The difference between fossil and solar steam turbine energy
One of the most important differences between these two is their operating cycle.
Solar gas turbines must be turned on and off repeatedly during the day to be efficient.
Weaknesses of solar turbines
One of the weaknesses of these turbines is that the heat transfer fluids cannot be heated above 400 degrees Celsius, but there is a solution to this shortcoming, which is to place the turbine on a tall tower with mirrors to focus sunlight directly on the steam boiler.
The boiler is the outside where the heat from sunlight is collected, and the mirrors used in the solar steam generator are two models: a circular parabola that focuses sunlight to a point and a cylindrical parabola that focuses light to a line.
Responsible countries around the world, realizing the value of non-renewable resources and the harmful effects of wasting them, are using solar steam generators.
