Abstract

System for keeping warm high power turbines, essentially steam turbines, based on the proper capactity of predicting the possible thermal behaviours of the machine as a function of temperature variations during cooling or heating, the system manipulating the temperature of the rotor and of the external shell of the turbine in order to obtain and keep within the turbine an order temperature appropriate to perform a fast start-up without requiring a preheating phase. The system is comprised of an assembly of heating blankets provided with electric resistances and placed against the external surface of the turbine, a data acquisition and automatic and computerized control system, and an electric power supply and distribution system.
