Preheating procedure for fast start-up of a steam turbine from a cold state

Preheating procedure for fast start-up of a steam turbine from a cold state

The paper describes a procedure that allows to start up a steam turbine in a significantly shorter period. The procedure is developed for start-ups that begin from a cold state, when the temperature of the parts of the turbine is close to the ambient temperature. The pre-heating rises the parts temp...
