Ensuring Design Indices for the Thermal Expansion of the Cylinder Casings in the T-100-130 and T-250/300-240 Turbines of TMZ in Their Installation and Overhauling

摘要

A technology ensuring the design indices for the thermal expansion of the casings of the steam-tur- bine cylinders in installation and overhauling is proposed. Taking the T-100-130 and T-250/300-240 turbines of TMZ as examples, it is shown that the problem of keeping their expansion within limits can be successfully Resolved without any radical changes in their original design.
