Abstract: Introduction: The role and importance of coal in ensuring national energy security is currently being reconsidered worldwide. Methods and materials: In this paper, the authors propose a new method for producing an energy-efficient water–coal fuel. This fuel is based on coal powder and biomass pyrolysis products, such as pyrolysis liquid, pyrolysis char and tar water, as well as a small amount of water. Results. The developed method was used to prepare a new water–coal fuel composition consisting of 20% coal powder, 30% biochar, 20% pyrolysis liquid, 15% tar water and 15% water. The structural characteristics of the resulting samples were examined using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). These analyses demonstrated that combining coal powder, biochar, pyrolysis liquid and tar water results in the formation of a stable, homogeneous and well-dispersed system at micro- and nano-scale levels. Tar water and pyrolysis liquid acted as natural dispersing and binding agents within the fuel composition. Conclusion: The developed method and technological scheme for producing energy-efficient water–coal fuel based on biomass pyrolysis products enables the preparation of an alternative water–coal fuel with improved energy, rheological and operational characteristics. The proposed approach provides a solid scientific and practical basis for the industrial application of such fuels.
