Abstract:

The lime process of rotary kiln is relatively complex，and the output and quantity of the products are influenced by material condition，material conveying speed，burning temperature，fuel supply，combustion air and main suction and other process parameters as well as working condition inside the kiln.Combined with lime process of the rotary kiln，this paper puts forwards technology of imitating biological neurons for model auto tuning by collecting online data with the basis of prediction technology of BP neuron network，and establishes high precision control model.The predictive control algorithm is an effective control algorithm with good applicability which can solve on\|site multi\|variable coupling effect and big time delay system.In practice，the burning process is controlled by burning unit and control system，the whole production system can run automatically according to the default parameters，and the limestone decomposes completely following the default temperature curve to produce high quality lime.
