“…To burn such fuels effectively, the development of special technologies and technical means is required. In this case, the technology of low-temperature vortex combustion in adiabatic combustion chambers is successfully used, such chambers are either integrated into the combustion chamber of existing or newly developed boilers, or installed next to the operating boiler [6][7][8]. At the same time, the designs of the combustion chambers must take into account not only the low reactivity of the WCF, but also the fact that when spraying WCF the flame length reaches 2.5 m and more, and the time for the WCF solid phase particles in the combustion chamber is from 1 s to 4 s. The heat generators work experience has shown that with a heat output of more than 2.0 -(3.0) megaW, the combustion chamber is built into the furnace space of the boiler without increasing its dimensions.…”

At a heat output of less than 2.0 -(3.0) megaW, the installation of a stand-alone (remote) combustion chamber is required [7][8][9].

Abstract. The sustainable development of distant areas of Siberia is associated with the structures of energy demand and supply, the implementation and promotion of the process of environmentally safe restructuring of the energy supply system. It has been established that suspension coal fuels derived from brown coal, coal mining, coal processing wastes can be used as fuel. The results of experimental and industrial boilers on suspension water coal fuel are presented. The designs of vortex combustion chambers of various powers are developed and tested. The possibility of using coal-enrichment wastes and substandard coals for the production of manure-coal fuel briquettes was studied. It is shown that the strength and thermal power characteristics of briquettes depend on the moisture content and degree of metamorphism of the raw materials. The most effective percentage of the solid phase and manure, as a binder, was determined.

“…For the implementation of this facility, the technology and equipment for the preparation of suspended water-coal fuel (WCF) based on the FDWCE of Kuzbass coal-preparation plants (CPP) have been developed and experimentally investigated. At the same time, a hot-water boiler with a thermal capacity of 0.5 (0.63) Gcal / hr (MGW) operating at the WCF was designed and manufactured [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

A significant environmental problem for the coal regions of Russia is the presence of large volumes of finedispersed coal sludges formed during the operation of coal mines and coal-preparation plants. In addition to direct environmental damage, storage of these sludges in sedimentation tanks, hydro-dumps or on sludge sites requires significant economic costs. Thus, the solution of the utilization problem of coal-enrichment wastes, especially finely-dispersed, represented by filter cakes of filtration compartments, containing practically all chemical reagents used in coal washing (flocculants, coagulants, etc.) is topical. The paper presents the results of research on the use of fine coalenrichment wastes as a fuel in boiler plants. It is shown that on the basis of these wastes it is possible to prepare a suspension water-coal fuel with a solid phase content of 56-60%, with the required structural-rheological characteristics and a net calorific value of up to 13 MJ / kg. A boiler with a thermal capacity of 0.63 MW with a vortex combustion system efficiently operating on fuel from coal waste was designed, manufactured and tested. The composition and effect of plasticizing additives on the rheological characteristics of the fuel is defined; the dependence of fuel consumption on its ash content is established. The results of the boiler operation on this fuel showed its high efficiency (the efficiency is 83-85%) with the level of harmful emissions in the flue gas significantly below the permissible values.
