Beschreibung
Zusammenfassung:	The invention relates to the technical field of turbines, in particular to an air preheating type quick starting system of a steam turbine. The air preheating type quick starting system of the steam turbine comprises a steam turbine high-pressure cylinder, a medium-pressure cylinder and a low-pressure cylinder are installed on one side of the steam turbine high-pressure cylinder, a condenser is installed at the output end of the low-pressure cylinder, a vacuum breaking valve is installed on one side of the condenser, an air preheating device is arranged below the steam turbine high-pressure cylinder, and a high-pressure cylinder warming steam inlet adjusting valve, a high-pressure main steam valve, a high-pressure main steam valve rear drain valve and a high-pressure adjusting valve are arranged at the joint of the air preheating device and the steam turbine high-pressure cylinder. According to the air preheating type quick starting system of the steam turbine, when a unit is started in a cold state, the air
