Abstract :
An instrument based on fuzzy modeling for online measurement of fouling in steam condenser is proposed in this paper. In the instrument, condensation pressure is chosen to reflect fouling state, fuzzy modeling is applied to separate the influence imposed by fouling on condensation pressure from other factors. During fuzzy modeling, T-S model is employed to approximate off-design condition condensation pressure, a fuzzy clustering algorithm based on similarity assessing is proposed to determine the optimal structure of the model. The instrument is constructed by a digit signal processor, and experiment on an actual steam condenser is carried out. The results show the instrument measures the fouling correctly, and is more effective than thermal resistance method or heat transfer coefficient method
