When converting heat into power, the pressure and temperature differences should be as high as possible.
By increasing the pressure in the turbine, engineers are able to increase the efficiency with which the force is transferred to the blade wheels in the turbines.
Secondly, the greater the temperature difference between the cooling water and the water vapour in the steam power plant, the more efficient the power plant process.
In power plant technology, an effort is therefore made to increase the upper temperature, since the temperature of the cooling water (e.g. river water) can hardly be changed.
