| Abstract: | To solve the problem influencing the condenser vacuum in a heating system,an analysis was conducted based on an introduction to the condensate recovery system,following which,the problem was found to be caused by the design defect lying in the layout of the connection pipe between the heating system and the condenser through static calculation,and subsequently the following 3 schemes were proposed,such as the addition of one-stage water seal,multi-stage water seal and electric isolation valve,respectively.By analyzing the advantages and disadvantages of 3 schemes,the scheme of adding a one-stage water seal is finally selected. |
