17. High Pressure Turbine
High pressure steam at 565°C and 156 bar pressure passes through the high pressure turbine. The exhaust steam from this section is returned to the boiler for reheating before being used in the next section of the turbine set.
Pauline says...
The blades in the high pressure turbine are the smallest of all the turbine blades, this is because the incoming steam has very high energy and occupies a low volume. The blades are fixed to a shaft and as the steam hits the blades it causes the shaft to rotate.
