Abstract

Fuel mixtures based on coal and oil sludge were studied. Waste cooking oil and distilled tall oil with a mass fraction of 5% in the mixture were used as additional components. In the experiments, the main energy and emission characteristics of the mixture combustion were determined for the subsequent calculation of the integral efficiency indicator using multi-criteria decision analysis. It was shown that the addition of tall oil provides higher (by 5–17%) fuel efficiency indicators compared to the addition of waste cooking oil. For coal sludge-based fuels, the additives had a positive effect on sedimentation stability, calorific value and combustion efficiency, ignition delay times, reducing the latter by 10–20%. In the case of oil sludge-based fuels, the oil additives had a moderate effect on the recorded characteristics.
