降低热水成本2.7元/t
具有较好的应用价值。
Abstract
Technical retrofit for the domestic water heating system in residential quater of one thermal power plant has been carried out by adopting the boosting and heating technology based on supersonic steamliquid twophase flow
to replace the original water pump and tube type heat exchanger.Four different schemes have been tested on the basis of load variation features concerning the hot water
obtaining optimal design parameters and operation mode.Utilizing heatand waterstorage functions of the pipeline
the buffering hot water tank has been eliminated.After retrofitting the said system.the requirements of hot water users can be completely satisfied
