The article investigates the processes of preparing liquid fuel based on a mixture of coal from the Alai deposit (Kyrgyzstan) and water with the addition of other components, for combustion in various power plants and intended to replace organic fuels (solid fuel, fuel oil and gas). On the basis of the research results, a technological scheme for the preparation of coal-water fuel from the organic matter of the Alai deposit has been developed. Methods and technologies for the preparation of coal-water fuel are described. As a result, an efficient and energy-efficient method for producing coal-water fuel has been developed, which has a high energy potential, environmental friendliness, low cost, a wide range of applications and a fairly simple technology for its implementation.
