Abstracts:

To determine the laws of combustion of coal-water fuel produced from coals of different metamorphism stages experimental studies of the ignition and combustion processes of coal-water fuel were carried out. The temperature-time characteristics of the ignition and combustion processes of coal-water fuel were obtained, the staging of the combustion process, ash shell structure and the burnout of combustible fuel mass were established as a results of the researches. A comparison of the experimental data for coal-water fuel produced from anthracite, which takes last location in a metamorphism stages, and coal-water fuel from brown coal, which occupies the initial position in a metamorphism stages were carried out. The same comparison was carried out for coal-water fuel produced from cannel (Flammkohle) coal, which occupies the middle position in the metamorphism stages. Main factors, which impact to combustion of coal-water fuel process efficiency, were determined.
