As Professor Senichi Masuda in Handbook of Electrostatics wrote, "The elect
rostatic precipitator is a typical fuzzy system, where a large number of fa
ctors affect its performance in a complicated fashion", (Masuda and Hosokaw
a, in: Chang, Crowley, Kelly (Eds.), Handbook of Electrostatic Processes, M
arcel Dekker, New York, 1995, pp. 441-479 (Chapter 21)). Knowing the comple
xity of ESP modelling from our previous experience (Kiss et al., VII, ICESP
, Kyongju, Korea, 1998, pp. 196-205), it was decided to approach the proble
m in a new way, which is based on fuzzy logic. In order to do that, a new c
oncept was worked out to analyse the applicability of combined models for E
SPs and to analyse such cases, which have no appropriate model. This paper
presents the fuzzy logic based ESP modelling and raises the possibility of
the wide range of its applicability. (C) 2001 Elsevier Science B.V. All rig
