Cement kilns have been identified as a stationary source that emit more than 25 tons of nitrogen oxides no x per year. this alternative control technique act document provides technical information for use by state and local agencies to develop and implement regulatory programs to control no x emissions from cement kilns.
Matlab fuzzy-toolbox was used to model and simulate the design. a comparison is made between the designed fuzzy system and the pid controller. simulation results show that it is possible to reduce accretion build up from 27 when using pid controller to 14.6 with the use of fuzzy control. keywords accretion, fuzzy logic, kiln, sponge iron 1.
This paper presents a fuzzy neural network control system for the process of cement production with rotary cement kiln. since the dynamic characteristics and reaction process parameters are with large inertia, pure hysteresis, nonlinearity and strong coupling, a fuzzy neural network controller combining both the advantages of neural network and fuzzy control is applied.
The cement kiln, which is the basic control object of represented work, is the most power consumption unit of the cement production. the wet production method provides a better quality of output clinker in north placed countries because of raw sources, which are already wet, and characteristics of portland cement.
Cement rotary kiln - great wall corporationcement rotary kiln, which is mainly used for calcinating cement clinker, is the main equipment of the new dry type cement.
