Question: (DMTO) What are the possible locations where steam leakage can occur in the turbine of the olefin separation unit? Steam leakage from the partitions at the tops of the moving and stationary vanes ； Leakage through the diaphragm due to the radial gap between the diaphragm and the rotor, as well as end leakage at the radial gaps where the turbine rotor passes through both ends of the cylinder! Note: The answers will be announced automatically in two days!
Such as steam leakage at the tops of the moving and stationary blades, steam leakage from the radial gaps between the shrouds and intermediate shrouds and the rotor, as well as the radial gaps at both ends of the cylinder where the turbine shaft passes through.
Under normal conditions, the areas where leaks may occur in a turbine are: 1. Air leakage from the steam seals in the low-pressure cylinder of the turbine; 2. Air leakage from the steam seals in the high-pressure cylinder of the turbine. Under abnormal conditions, leaks can also occur at the joints between the cylinders, as well as at the main steam valve and control valves.
