How long does it generally take to warm up a steam turbine?

Warming up a steam turbine is a crucial process that generally involves gradually increasing the temperature to prevent thermal shock and ensure optimal performance. Typically, the warming up period spans 10 to 15 minutes. This timeframe allows for the gradual expansion of materials, reducing the risk of stress and potential damage from rapid temperature changes. While proper warm-up is vital, it needs to be balanced with operational efficiency. Thus, 10 to 15 minutes is recognized as a standard warming period that aligns with both safety and functionality considerations for steam turbines.
