The article contains information on the work of the department of thermal heterogeneous processes of the Institute of Gas of the NAS of Ukraine over the past ten years, devoted to the development of scientific and technological foundations for the thermal treatment of dispersed materials. The problem of the efficient use of natural resources in connection with the reduction of fossil energy resources while increasing their demand to meet the growing needs of production is discussed. The results of mathematical modeling of the heat treatment of dispersed materials are presented — a detailed study of the co-combustion of wood particles with natural gas is carried out taking into account the main stages of the process, a methodology for the qualitative and quantitative analysis of the process of dioxin formation during high-temperature processing of chlorine-containing waste is described. The possibilities of using carbonate sorbents for trapping sulfur compounds are evaluated. A detailed mathematical description of the endothermic process of calcining limestone particles during its passage through the high-temperature zone of the heated inert particles of the fluidized bed is carried out. The technology of three-stage processing of material in fluidized-bed apparatuses and the design of a reverting furnace combined with a recuperator, which is an element of energy conservation, have been developed. Created and implemented technologies in production of heat-insulating materials from hydrosilicates, perlite, mineral wool products. Schemes, dependencies of technological parameters, technical characteristics and general view of the implemented developments are given. Ref. 27, Fig. 10, Tab. 2.
