What are the chemicals used in power plant?

Answer 1

if by gas you mean natural gas, which is primarily methane:

CH4 + O2 => CO2 + H20. There are other reactions such as the formation of NOx emissions among many other things but the reaction listed is for a theoretical complete combustion.

Answer 2

We normally see very little in the way of chemical reactions taking place in a nuclear power plant. The main chemical task on a nuclear power plant is to keep the water used as a coolant for the reactor pure. We'll also be monitoring the chemistry of the feedwater to the steam generators. As we need to keep the mineral content to a minimum, we'll see that a demineralisation plant is an important part of the station infrastructure.

If you are thinking of events in Japan, the hydrogen which has caused explosions has come from reactor cooling water being exposed to very hot fuel elements, this is really a physical process causing the water to break down into its constituents, i.e., hydrogen and oxygen.

Answer 3

The power comes from heat in the ground, so there are no chemicals actually used up there. But there may be Freons in heat pumps, lubricants for motors and valves. Paints, detergents and degreasers to keep everything neat and tidy.

Answer 4

A nuclear power station uses nuclear materials (materials, not fuels) such as U-235 to convert nuclear energy into energy that can be utilised (utilised not used).

Answer 5

usually water

Answer 6

Tri sodium phosphate
