| Abstract: | This paper deduced a soft sensor mode on fouling thermal resistance by using the thermal balance theory and fluid mechanics and designed an on-line monitoring device of fouling thermal resistance.Three functional models(Logistic,polynomial and S function model) were combined and compared in fitting the fouling thermal resistance based on the data series derived from monitoring device,so a mathematic mode that the variations of fouling thermal resistance of the transfer tube with the time was obtained.In the end,the model was theoretically discussed and demonstrated. |
| Keywords: | soft-sensor technology fouling thermal resistance time series |
