the steam generated in the boilers is then supplied to the turbine, which is coupled to a generator. the steam is supplied via 2 out of 3 boiler feed pumps. two pumps are always active, while one pump is on standby. the turbines run at a constant speed of 3000 rpm, so as to provide a steady output of 50 hz. the turbines are divided into 3 parts : high pressure (hp) turbine, intermediate pressure (ip) turbine and a low pressure (lp) turbine. the steam is supplied to the hp, which sends it back for reheating. this reheated steam then goes to the ip and the lp, which in turn run the generator to produce electricity.
