Abstract
An application of the method of creating inverse temperature non-uniformity for steam turbine high pressure cylinder inner split housings by controlling their heat state in the starting and variable modes is studied. Criteria are defined, namely: temperature differences between steps; constant difference of total tangential stresses from the pressure difference on the wall of the cylinder body; tangential stresses of the temperature with the linear law of temperature change along the radius of the cylinder, regulation of which, according to their respective programs, allows to stabilize the heat state of the cylinder body when starting a turbine from various thermal conditions and exploiting it in variable modes. Technical solutions are proposed aimed at increasing the technical and economical characteristics of the operation of steam turbines and power unit.
