Okay kiddo, so let me explain to you what a combined cycle power plant is.
Imagine a big machine that can turn different things into electricity. This machine needs something called fuel to work, which is kind of like food for us. Just like how we need food to have energy to move and play, this machine needs fuel to make electricity.
Now, some machines like this one only use one kind of fuel, like coal or natural gas. But a combined cycle power plant is special because it uses two different kinds of fuel to make even more electricity!
The first kind of fuel is natural gas. This gas gets put into a big machine called a gas turbine, which turns it into electricity. Think of it like a magic trick where the gas disappears and turns into electricity!
But that's not all. After the gas is used up, there is still some energy left in it that wasn't turned into electricity. So, the second kind of fuel, which is steam, comes in to help out. The steam goes into another machine called a steam turbine, which also turns it into electricity. This is like a second magic trick where the steam disappears and turns into electricity too!
Now, you might be wondering how the steam gets made. That's where the leftover energy from the gas turbine comes in. Remember how I said there was still some energy left in the gas even after it was turned into electricity? Well, that energy is used to make steam. It's kind of like using the leftovers from dinner to make a new meal!
So, that's how a combined cycle power plant works. It's like a big machine that can use two different kinds of fuel to make electricity efficiently. Pretty cool, right?
