Hello

Let's take as example a gas fired turbine used for electricity. In the turbine enter air and fuel (gas) . the turbine + the generator reach 3000 rpm (3600 valid for Canada and USA) and the extra energy obtained from fuel burning will not increase the number of rotations over 3000 (3600) but will increase the MW produced. On the other side, the energy of burnt gases after they have been used in the gas turbine it can be used entering in HRSG ( heat recovery steam generator) where it is produced steam ( used for producing electric/thermal energy).

I hope I was clear enough.
