摘要

A method for the techno-economic calculation of the losses incurred from operating a type T-250/300-23.5 turbine after the removal of its last-stage bucket as a function of the fractional annual operating times in condensing and in cogeneration regimes is described. It is shown that the use of the restored bucket is unadvisable from a technological and economic standpoint. To ensure the reliable operation of the turbine after the removal of its last-stage bucket, the condenser pressure should be raised.
