Abstract

Abstract:

In the steam turbine of a power plant, the heat pump technology was used to recover the great amount of lowtemperature waste heat of circulating

water for heat supply in winter. The theory of the circulating water waste heat recovery by the heat pump in the power plant was introduced. The problems

occurred during debugging were analyzed，and improvement measures were proposed, which can be used as reference for popularization and application of the

technology and relevant feasibility study and design.
