Why isn’t the pressure in the cylinder behind the turbine allowed to be too high
Excessive pressure, which is essentially a low vacuum level, causes the exhaust temperature in the rear cylinder to rise; when this temperature exceeds 65 degrees, thermal expansion occurs, the center of the cylinder rises, resulting in a reduction in the clearance between moving and stationary parts and increased vibration, thereby threatening the safe operation of the turbine.
