- Abstract
The analysis of literary sources in the field of gasification of water-coal fuel is presented. The results of theoretical studies of the physicochemical laws of gasification and determination of the most expedient operating parameters based on the calculated composition of synthesis gas using a mathematical model of heat and mass transfer processes occurring with a moving fuel particle in the volume of the gas generator are considered. Comparison of theoretical and theoretical and experimental data of the process of low-temperature gasification of water-coal fuel on air and oxygen blast, demonstrating the adequacy of this model. Conclusions are made about the main advantages and disadvantages of using this method of coal combustion. It is shown that one of the most promising technologies for the energy use of coal is the preparation of coal-water suspensions, which are composite liquid fuel with predetermined technological and rheological properties to ensure minimum operating costs during its preparation, storage, transportation, combustion or gasification. The main results of work on the cavitation treatment of a coal-water suspension and fuel preparation obtained by the authors of the articles are presented
