| Sumari: | Title screen Composite fuels based on various wastes are a promising alternative to conventional energy resources. Co-combustion of waste-derived components is characterized by synergistic effects that have a significant impact on combustion performance. This paper presents the results of an experimental study of thermal decomposition characteristics and combustion kinetic parameters for composite fuels based on typical lignite, coal refinery waste, sawdust and used motor oil. Thermogravimetric analysis revealed the influence of individual component properties on the characteristics of their combined thermal oxidation in mixtures. The experiments were carried out in a temperature range of 25–1100 °C, corresponding to industrial combustion chambers. Conditions were identified that ensure significantly higher rates of thermal conversion of fuel mixtures than those of individual components. The influence of heating rate on thermal decomposition of mixed fuels was determined. The dependences of the activation energy of thermal decomposition on the content of volatiles and carbon, as well as ash content and humidity, were obtained. The experiments have shown the conditions under which the size of solid particles, their hydrophilicity and hydrophobicity have a significant influence on the characteristics of the thermal oxidation of fuels. Mathematical expressions were obtained for calculating kinetic characteristics of thermal oxidation of different types of coal using the known properties of the components Текстовый файл AM_Agreement |
