The Research And Application Of Intelligent Pulverized Coal Injection System Of Rotary Kiln

The pulverized coal injection system is the main electric equipment that be special stress on protecting for the rotary kiln. It injects the pulverized coal to the rotary kiln, offers essential temperature for the rotary kiln through burning the pulverized coal. Its safe and continuous run plays a very important role to the production process, so the demand of its dependability and accuracy is very high The development of technology of the computer and intellectual control has offered a good application platform for high quality control of the pulverized coal injection system.Aim at the complexion that the actual operation parameters and the craft establish parameters of the pulverized coal injection system before alteration can not keep unanimous, we take the difference of the actual operation parameters and the craft establish parameters of kiln head temperature, kiln trail temperature and the CO content and the variety of the difference as input, take the adjustment amount of the flux of pulverized coal and the opening degrees of the valve as output, establish a fuzzy control system possess multi-input and multi-output. Then we introduce the learning ability of neural network into the fuzzy control system, use the separate neural network to express the fuzzy treatment, the fuzzy reasoning and the accurate calculate, Last, we design designing a kind of new-type pulverized coal injection system based on the arithmetic of fuzzy neural network.Main content described in this article is as follows:(1) Brief introduction of the appearance, solving and effect of this problem.(2) Research of the fuzzy control arithmetic.(3) Analyse of the principle and learning arithmetic of neural network.(4) Discussion of the arithmetic of fuzzy neural network.(5) Detailed dissertation of the application of the arithmetic of fuzzy neural network in the pulverized coal injection system of rotary kiln.
