Fossil Fuel Power Plants Explained A fossil fuel power plant works similar to a football team playing in a grand final. At the start, before the match the players run out onto the field all pumped up ready for the big game. They are all full of energy because they haven't started playing yet. This is similar to the coal being loaded into the burner. It is full of chemical potential energy because it hasn't done any work or "started playing" yet. When the football players start playing, they begin to sweat and get hot. They are burning off energy. This is like when the coal is being burnt in the burner. The chemical potential energy is being changed into heat energy. As the football players are playing and are warmed up they get really focused and into the game. They are playing with passion. This causes the spectators to get warmed up and involved. This is like the heat from the coal being burned turning the water into steam in the fossil fuel power plant. When the spectators get involved, they often put pressure on the opposition to make a mistake. This is similar to the steam in a power plant putting pressure on the turbines to move. The turbines don't want to move, like the opposition doesn't want to make a mistake, but the force applied so great that the turbine/opposition has no choice. When the opposition makes a mistake, they give away a free kick. This action causes the umpire to get involved. In a fossil fuel power plant, the umpire is the generators. Because the turbines have given in and 'made a mistake', they force the generators to move. Comments:From judysara - 6/14/05 8:03 PM Good attempt at an analogy.
From katina - 6/10/05 8:16 AM The analogy is on fossil fuel power plants because Chelsea, the person writing up the alternative power source, has been away sick for most of the week
