Modelling of the Fuel Stream and Combustion in a Rotary-kiln Hazardous Waste Incinerator
Hazardous wastes from various industrial processes are normally incinerated with rotary kilns in order to comply with current environmental regulations. They have often very complicated chemical compositions in a variety of physical forms and difficult to characterise. The complex transport phenomena within the incinerator are not well understood, and the incineration process expects large unce...
متن کاملIncineration of Industrial Wastes at a Large Multi-product Manufacturing Plant
The 3M Company incinerates chemical wastes from manufacturing operations in a 23 M kcal/hr (90 MM Btu/hr) rotary kiln incinerator which has air pollution control equipment. This paper deals with the essential features which have resulted in this successful incineration operation for industrial wastes. These features include waste materials handling considerations, design aspects, and main tena...
متن کاملIdentification of Cement Rotary Kiln in Noisy Condition using Takagi-Sugeno Neuro-fuzzy System
Cement rotary kiln is the main part of cement production process that have always attracted many researchers’ attention. But this complex nonlinear system has not been modeled efficiently which can make an appropriate performance specially in noisy condition. In this paper Takagi-Sugeno neuro-fuzzy system (TSNFS) is used for identification of cement rotary kiln, and gradient descent (GD) algori...
متن کاملIdentification of Multiple Input-multiple Output Non-linear System Cement Rotary Kiln using Stochastic Gradient-based Rough-neural Network
Because of the existing interactions among the variables of a multiple input-multiple output (MIMO) nonlinear system, its identification is a difficult task, particularly in the presence of uncertainties. Cement rotary kiln (CRK) is a MIMO nonlinear system in the cement factory with a complicated mechanism and uncertain disturbances. The identification of CRK is very important for different pur...
متن کاملInfrared Camera-based Detection and Analysis of Barrels in Rotary Kilns for Waste Incineration
Rotary kilns are widely used for the thermal treatment of highly toxic waste. The waste (mostly organic compounds) is packed in barrels before it is fed in the kiln. Depending on the compound the heating inside the kiln leads to deflagrations of the barrels associated with an incomplete burnout. In this paper we present a new method to detect and track waste barrels in infrared image sequences ...
