“…At the same time, finely dispersed waste coal of 0-0.5 mm grain size, commonly represented by filter press cake, is sent to waste dump together with waste rock. The filter cake yield is up to 7 % of being prepared coal mass [1][2][3][4][5][6][7][8][9][10][11][12]. Dispatching this product to waste dump with waste rock is caused by the fact that its use is complicated by high ash content, up to 50 %, and moisture content up to 45 %.…”

The process and equipment have been developed for preparation and burning (at small and medium capacity boiler plants) of slurry coal-water fuel, produced from finely dispersed coal preparation waste (filter cakes) from coal preparation plants of Komsomolets Mine and Named after S. M. Kirov Mine. It was shown that, based on these wastes, it is possible to produce slurry coal-water fuel with solids content of 56-60 %, the required structural and rheological characteristics, and lower heating value of up to 13 MJ/kg. Based on the research findings, detail design was developed for creation of the pilot process complex for processing of waste coal to produce slurry coal-water fuel for burning at boiler plant. Assessment of using the whole volume of the SUEK Kuzbass coal preparation plants waste coal at the nearby Belovskaya SDPP was performed, which showed high economic and environmental efficiency of the proposed project.

Annotation.A feature of modern coal preparation plants (CPP) in Russia is the use of closed water slime schemes (without discharging slurry water outside the plant to external waste dumps) and the lack of thermal drying of small classes of coal due to their effective mechanical dewatering. As a result, a significant amount (up to 10-12% of the volume of coal processing at the plan) of toxic fine-dispersed coal-enrichment waste (FDCEW) with a particle size of less than 0.5 mm, humidity of 30-45% and ash content of 25-65% appeared. This product is not in demand on the market, it is very difficult to process and, as a rule, it is shipped outside the factory with the breed or separately by road to waste dumps or sludge collectors. Considering the high toxicity of the FDCEW, due to the presence on the surface of particles of flocculants and coagulants used on CPP, which have carcinogenic and mutagenic effects, the storage of such wastes is associated with a high hazard, which creates significant environmental problems in the region. To solve the problem of using the FDCEW, a technology and a set of equipment have been developed for obtaining on their basis suspension coal-water fuel (CWF) and its efficient combustion with the capture and disposal of ash and slag waste (SW) generated. In addition, it is intended to use the fuel obtained at coal-steam plants (CSP) and regional hydro-electric power plants (RHEPP). In this case, by increasing the volume of combustion, an economic and ecological effect is achieved.

The baseline conditions of technology for producing and burning coal-water slurries in Russia and foreign countries is exposed. The technological and economic efficiency of using this technology for the coal processing and cleaning waste disposal is shown at experimental and industrial facilities. The feasibility studies of the technology usage at large Kuzbass thermal power plants are presented. The possibility of solving a serious environmental problem of reducing the storage of the most coal washing toxic waste volume in the areas where coal processing plants and coal mining enterprises are located is demonstrated. It is shown that on the basis of these wastes, it is possible to prepare a suspension coal-water fuel with a solid phase content of 56-59%, with the required structural and rheological characteristics and a lower calorific value of up to 13 MJ/kg. The boiler with a thermal capacity of 0.58 MW with an eddy combustion system, which effectively operates on coal-processing waste fuel is designed, manufactured and tested. The results of the boiler operation on the specified fuel showed its high efficiency (efficiency is 83-85%) with the level of harmful emissions in the flue gases significantly lower than the permissible values.
