Abstract
The thermal method of management of municipal waste has a number of advantages over other methods. Especially significant are the decrease in the waste and the produce of additional thermal and electrical energy. Waste incineration technology is widely used in many countries. The application of a multi–stage emission control system minimizes pollution of the environment. The waste incineration process is a complex mechanism due to the heterogeneity of composition of the waste. The goal of the research is to build an analytical mathematical model of mixing of components in a rotary kiln. The model is based on the mathematical apparatus of Markov chains. The model allows to determine the concentration of the key component in any elementary volume of material circulating in the rotary kiln at any time and to calculate the statistical characteristics of the homogeneity of the mixture. The model can be used to optimize the recycling process. For a batch–type machine, the proposed model allows to evaluate various sequences of charging of components. In the future, the model will be used to research new designs of the equipment with rotary kilns.
