FEATURES OF THERMAL COOXIDATION OF COMPONENTS OF ALTERNATIVE LIQUID FUELS

Results of experimental studies of the characteristics of separate thermal oxidation and cooxidation of advanced components of alternative liquid fuels have been presented with the example of brown coal, water, and waste motor oil. The temperature range in the experiment was 25–1100 o C. The influence of the properties of the components of the fuels on the characteristics of thermal cooxidation as part of the blend has been established. The use of the addition of waste motor oil as part of the composite fuel allows reducing the burnout temperature by 18% compared to coal, and also decreasing activation energy at the stages of volatile yield and thermal oxidation of solid carbon residue by 43 and 52% respectively. Synergetic effects of thermal cooxidation of components of fuel blends have been singled out. The value of the synergetic effect resulting from the cocombustion of components as part of the composite fuel amounts to as much as 1.72 and 1.92% when the suspension fuels "60% coal and 40% water" and "50% coal, 40% water, and 10% oil" are used
