Before starting, the turbine needs to be warmed up at low speed, primarily to gradually increase the temperature of the cylinders and rotor, thereby reducing the thermal stresses resulting from differences in thermal expansion among the internal components of the equipment, and preventing deformation of the rotor and cylinders or damage to the components. This slow and uniform heating process helps ensure the safe operation of the equipment and extend its lifespan. .
