“…The heat and mass transfer of rotary kilns were researched, for example, by Chen et al [14] and Silcox and Perching [15]. Further research work can be classified as thermal conversion investigations in oxygen-rich [16,17] and oxygen-free [18] atmospheres, as well as other topics [9,19].…”

The present paper focuses on developing a novel virtual representation framework for optimizing standalone hazardous waste rotary kiln incineration plants. A digital support tool can be provided to optimize the plant's waste management, operation, and maintenance by combining thermochemical-based simulation models with a fuel classification system. First of all, the virtual representation can be used to determine the waste composition of not entirely analyzed waste streams. Furthermore, the determined waste compositions of historically fed waste streams can be used to enable further advanced applications. The determined waste compositions are linked with the appropriate waste code and supplier, which first enables the monitoring of the delivered waste streams. In the case of recurring fractions, the virtual representation can be used to optimize the barrel sequence to reach homogenous waste inputs. Additionally, the plant operation can be optimized regarding stable operation conditions due to the knowledge about waste compositions of recurring fractions. The parametrization results fit very well with the comparable sensor values. Therefore, the novel virtual representation of the hazardous waste incineration plant could definitely make a reasonable contribution to optimize the efficiency of thermal waste treatment within the hazardous waste sector in Austria and Europe.

“…This is particularly important in the process of hazardous waste incineration, as postprocess waste should not be harmful. This effect is achieved when the process is carried out correctly, which is largely influenced by the residence time of the waste in the reactor and the degree of its mixing [11][12][13]. An analysis of the essential characteristics of the material motion could be performed by adapting the universal theory of flows described, among others, in [14,15].…”

The motion of input material in a rotary kiln is an important aspect of its operation. This can be observed especially in the case of the implementation of the hazardous waste incineration process in this device. The values of the flow parameters, mainly the residence time and the degree of mixing, can determine the proper and safe treatment of waste. The relationships that occur in the layer of solid material in a rotary kiln have not been completely recognized. This article presents a research method that involves an experiment on a laboratory stand simulating a rotary kiln in association with a dedicated algorithm. Multi-criteria tests were carried out. The adopted research method was the tracer method. It used a tracer which, subject to the same transport conditions as other material particles, provided information on the characteristic of the motion of tested materials in the rotating cylinder. The application based on the residence time distribution (RTD) algorithm returned information about the characteristics of the motion of the material in the rotary cylinder in terms of residence time distribution and the degree of mixing. This tracer method, together with stimulus impulses on the grate and a dedicated RTD algorithm, was used here as a sensor method to examine the characteristics of material motion on various grate systems. The data obtained as a result of this research may include, among others, the boundary conditions for numerical simulations of processes carried out in a rotary kiln.
