In this paper, a two-layer NN approach and a mathematical
model that can predict the OBD of air cyclones
have been described. Five hundred five different artificial
scenarios given in a wide range of five main operating
variables were solved based on proposed empirical
equation and a two-layer NN model. Results obtained
from these two categories were compared with Kalen and
Zenz’s model, and significant points of the proposed approaches
were evaluated.
Both developing a new mathematical model and creating
a NN model on OBD values promoted the existing
calculation method, and gave favorable results for desired
values. The OBD equation was written as a different
function of gas flow rate, number of cyclones, temperature,
particle density, and Ka and Kb values in a different
unit system. The gas density (rf) and gas viscosity
(mG) variables used in Kalen and Zenz’s model were
eliminated by using the proposed OBD model. Both the
proposed model and NN outputs showed a good prediction
on OBD values under 505 different artificial scenarios.
Choosing an appropriate data set depending on
the ranges of input variables showed a good performance
for stochastic modeling approaches presented in this
study.
