METHOD OF OPERATION OF EXTRACTION TURBINE TO HEAT SCHEDULE Russian patent published in 2000 - IPC

FIELD: heat power engineering; thermoelectric plants. SUBSTANCE: method of operation of extraction turbine comes to change-over from operation with steam passed from high-pressure cylinder through receiver into low-pressure cylinder, to high-pressure cylinder backpressure operation by fitting plugs at high-pressure cylinder outlet and low-pressure cylinder inlet, and by replacing rotor of the latter. Diaphragms are removed from low-pressure cylinder, and rotor is replaced by shaft with cylindrical disks whose summary weight and mass moment of inertia is not less than summary weight and mass moment of inertia of disks without working part of blades. EFFECT: improved reliability, simplified design, reduced labour input in manufacture at preservation of economy of extraction turbine. 1 dwg
