Embodiment Construction
[0012] The present invention proposes a new method aiming at the deficiencies of the three detection methods in the current prior art. In this method, the heat transfer end difference is used as an important performance index reflecting the heat exchange condition of the condenser, and the effect of each factor on the end difference is considered comprehensively. The fuzzy modeling method is used to realize the separation of condenser fouling and the effect of working condition parameter changes on the end difference, so as to accurately monitor the condenser fouling online. It is characterized in that after thoroughly cleaning the condenser, first measure the heat transfer end difference of a given working condition, and this end difference is the end difference corresponding to the working condition in the clean state, and then change the working condition to run , and then measure the above-mentioned heat transfer end difference to obtain the change end difference between th...
