Some actual aspects of advancement the problem of improvement the heat exchange equipment are considered in the paper. First of all the actual items related to middle and high temperature recuperators are discussed with proper up-to — date approaches. The classification of flue gases heat recovery appliances has been proposed along with the statement and analysis of the main characteristics of the recovery plants and option the ways of optimization the mentioned characteristics. The problem of Reynolds analogy (similarity of relative change the heat transfer phenomenon and variation the hydraulic resistance) within the channels of different purpose and of various cross-section supplied with and without the obstacles has been analyzed in application to separate cases of flow along the surfaces equipped with the cavities (dimples) or the convex elements. Thermal Performance Factor (TPF) of the heat exchange process is qualitatively like to Reynolds analogy factor and is highly depended upon rate of heat transfer and of friction factor in conditions of the scheme under consideration for flow over the surface or flow within the channel. The various media has been compared used as a working body in the heat exchanger’s channels: gaseous, liquid and the nanofluids, the last appeared in practice since 2000. Analysis has been carried out on effect of using the secondary energy emitters (SEE) arranged inside the tube channels, on resulting heat flux by heat exchange between outward flow of combustion products and the inner air flow.

The International Investment Project «Creation in Ukraine of a High-Tech Complex for Processing Coal into Motor Fuels» provides for the use of a technological line for growing algaes, by utilizing significant technological waste from the main technological lines of the Project (low potential heat; methane gas from degassing of a raw mine; the remainder of the air distribution for the production of process oxygen; carbon dioxide obtained from coal gasification, etc.). Hydrothermal carbonization is currently the most advanced biomass processing technology. It completely prevents pollution and has a number of significant advantages over other methods of biomass treatment. These advantages make it possible to consider hydrothermal carbonization to be the best available technology for the production of biochar, liquid biofuel and other products from non-food biomass.

On the basis of gas-burning devices of the GS series, new devices have been developed, in which gas channels are installed for operation in the mode of maximum or minimum flame length. This allows to increase the stability of the flame at low temperatures of the working space (below the natural gas ignition temperature), which in turn provides an increase in the economic performance of the tunnel kiln firing ceramic bricks.

The paper discusses the technologies of reducing the concentration of nitrogen oxides in the exhaust flue gases during the combustion of coal in the boiler units of power plants that produce heat and electrical energy. According to the results of the analysis, the influence of the method of oxidizing gaseous nitrogen oxides on the efficiency of the treatment plant was revealed. It has been established that during the reconstruction of the gas cleaning system, the advantage is in the technology in which, at the first stage, a gaseous oxidizer is added to the gas flow to convert nitric oxide into heavier water-soluble compounds. At the second stage, an aqueous solution of alkali metal compounds or ammonia is injected into the gas mixture for chemical bonding of the products of oxidation reactions. Thus, this technology allows reducing the concentration of nitrogen oxides in flue gases by 90–95% and meeting the requirements of regulatory documents on emissions of pollutants into the environment.

A new approach to providing the necessary temperature of technological equipment of various industries, in particular, chemical, food, microbiological, heat and power, and therefore a stable thermal mode of processing the flows of substances and materials that are in the specified equipment is proposed. It has been proposed to make working bodies and elements of equipment in contact with the flows of the substances and materials being processed from magnetic material with a phase transition temperature of the second type (Curie point), which corresponds to the temperature of the technological process. The designs of tubular heat exchangers, dryers, packed and disc mass transfer columns, separators, equipment for the processing of thermoplastics (extrusion head, static mixers, worm extruder), as well as bulk feeder are considered.

The paper substantiates the need to replace fossil coal in local solid fuel boilers by biocoal produced from various types of agricultural waste. Selection of the best available technology for biocoal production should be based on an integrated assessment including economic, environmental and social aspects. It is noted that direct combustion of agricultural waste does not meet environmental safety standards and also requires significant costs for modernization of existing boiler equipment. It is proposed to produce biocoal from agricultural waste using modern methods of thermochemical treatment — torrefaction and carbonization. End-products of biomass torrefaction — biocoal pellets or briquettes — have high calorific value, low sulfur and heavy metal contents, and low nitrogen oxide emissions. Hydrothermal carbonization is currently the most advanced biomass processing technology. It completely prevents pollution and has a number of significant advantages over other methods of biomass treatment. These advantages make it possible to consider hydrothermal carbonization to be the best available technology for the production of biochar, liquid biofuel and other products from non-food biomass.

When implementing a number of high-temperature processes with heat supply to the reaction zone (allothermic processes), it is impossible or economically inexpedient the burning of fossil fuels to achieve the required temperature level. The possibilities of these processes implementation through the use of electrothermal fluidized bed (ETFB) techniques are considered. Such processes include, for example, the production of hydrogen by the pyrolysis of hydrocarbon gases, the production of silicon carbide and other carbides, the production of artificial graphite and the thermal purification of natural graphite, the high-temperature heating of gases and gas mixtures. These processes can be carried out in the temperature range of 600–3000 °С using fine-dispersed materials or directly in the gas phase using ETFB. In a number of processes ETFB technology can be applied as a source of high temperature gas production, used either for the implementation of this technological process, or for ensuring the operation of technological or heat engineering equipment. Also considered the main structural characteristics of the equipment that ensure the implementation of processes in the ETPS. Bibl. 37.
