End-of-Life tires (EOLT) are ones of the most dangerous waste in the world. They do not practically decompose in nature. Because of this their sound treatment is needed for the environment protection. One of the possible methods for such a treatment is pyrolysis process. It is well known [3, 4] that globally around 23% of all EOLT are processed through pyrolysis, whereas in the Republic of Bulgaria only 5% are processed by this method. Thus for Bulgaria it becomes clear that the pyrolysis method for EOLT treatment still has a good potential for usage, development and further research. This method is very complicated for modeling and studying, because it is 3D and non-stationary. In our previous work [1] we created an adequate mathematical model and numerical algorithm in MATLAB for numerical solving the mathematical initial and boundary value problems for model equations which describe pyrolysis process used for the treatment of the End-of-Life tires (EOLT). Some results for the temperature field for several characteristic periods of operation of pyrolysis station are presented and commented in the papers [1, 2, 5]. This paper deals with studying the influence of two-burner heating upon the heat transfer during EOLT treatment by pyrolysis process. The results for temperature fields, temperature isolines and gradients at some specific moments of time and for two different initial heating functions are graphically presented and commented. Results from this modeling can be used in the real pyrolysis stations for more precise displacement of heathers and measurement devices and for designing of automated management of the process.
