Combined cycle power plants are unique systems that, similar to CHP systems, make use of waste heat to create additional power. They are an efficient and environmentally-friendly alternative to fossil fuel plants, allowing high levels of energy to be produced without negatively impacting the environment. In this blog, we’ll delve into CC systems to help you gain a better understanding of this ever-popular technology.
What Is a Combined Cycle Power Plant?
Using both a steam and gas turbine in unison, CC plants can effectively produce electricity and utilise the leftover waste. It does this through a uniform process. Firstly, the gas turbine combines compressed air and fuel before heating this to a high temperature. This makes the turbine blades spin, driving a generator that utilises kinetic energy into electricity. The heat generated from the exhaust is then captured through a heat recovery system, turned into steam and pushed through the steam turbine.
Here, this energy is processed through the generator drive shaft and is converted into extra energy which can be utilised effectively. It is estimated that CC power plants can generate approximately 50% more electricity from a single fuel than traditional models.
Advantages of a CC Power Plant
- Adaptable to the demands and production requirements at any given time – Because of their design, combined-cycle plants can be adapted to work at partial or full capacity at any given time. This is particularly beneficial when working with renewable energy sources, including solar and wind energy with the ability to adapt to needs along with changing weather conditions.
- Increases energy capacity for improved efficiency – This form of technology is designed to optimise efficiency, meaning you get a better energy yield vs consumption balance.
- Reduced emissions – These systems don’t require standard fossil fuels and therefore release fewer pollutants, including CO2, SO2 and NOx.
- Less water wastage – CC plants only need water for the steam condensation process. This reduces requirements and wastage significantly from standard plants and can often be powered with water that is not suitable for human consumption and, therefore, widely wasted.
- Less infrastructure is required and can be built in under 2 years – Because of their light, modular design, CC plants are quicker to erect and can be put into action significantly faster. They also require fewer electricity lines.
- Lesser operating costs
- Fewer maintenance requirements – Due to the modular design.
