This paper has given out a reasonable regulation method of Low-Vacuum circulating water heating on base of the study on the Water Heating System of Anshan Thermal Power plant. The regulation method can be considered a theoretic guide to the system's operation.
Theoreti calclaculation and practice show that importance should be attached to the stability of unit vibration and regulating system,when circulating water heating is being used to turbine instead of regulating extraction.
With the help of an engineering case,this paper introduces the application of steam-turbine circulating water heat supply technology in an unit on low vaccum running,analyses its effects in economy,and discusses its safety in the operation.
In order improving economic efficiency of condensing steam turbine generator, this article discussed some theory and technology questions of using recirculating water offering heat in winter, included analy- sis and calculation of thermodynamics. economic indicator. system arrangements, economic benefits etc. Expouned more completely the feasibility of condensing steam tur- bine generator using recirculating water offering heat. This article have important reference value and guiding function to improving e...
