The document describes the turbines and thermal power plant at Pakistan Steel Mills. It states that the boiler at the plant can generate 220 tons of steam per hour at a pressure of 115kgf/cm^2 and a superheated steam temperature of 540 degrees. The thermal power plant has 3 turbines with a rated power output of 55MW each that use steam from the boiler. The turbines have extraction points and operate at speeds of 3000rpm and a frequency of 50Hz using steam that is 525-540 degrees C and at a pressure of 85-95 kgf/cm^2.
