“…9, S5, and S6 allowed evaluating the effect of coal concentration reduction in the slurry at all values of fuel and air pressures. Experimental results indicated that lower viscosity and density of ACWF in accordance with [88,89] have an effect on the formation of droplets of small and medium sizes. This is typical for all studied ACWFs and is explained by the fact that the higher the viscosity, the smaller the changes in the longitudinal and transverse sizes of droplets that are twisted and transformed due to stretching and compression [90,91].…”

The results of spraying characteristics of alcohol‐coal‐water slurries are presented. It has been experimentally proved that the lowest viscosity value of the studied slurries varies from 54 to 329 mPa s. The density value of alcohol‐coal‐water slurries decreases to 1130 kg m−3 when the content of isopropyl alcohol in the fuel composition is 8 wt %. The largest value of jet spraying angle corresponds to alcohol‐coal‐water fuel with an isopropyl alcohol content of 8 wt %. The number of sufficiently large droplets decreases in comparison with a typical two‐component coal‐water fuel. The calorific value of alcohol‐coal‐water slurries rises when the third liquid fuel component is introduced into the composition of coal‐water fuel.

“…The droplets of liquid hydrocarbons collide with each other after spraying and form new fragments or retain their integrity. The destruction of rather large droplets depends on the density ratio of air-to-liquid hydrocarbon [51]. High values of the ratio facilitate the droplet deformation and its subsequent destruction.…”

Experimental studies of the steam pyrolysis of oil sludge were performed using a flow-type pilot plant with 300 kg/h capacity (raw material) to obtain energy-valuable products, such as liquid hydrocarbons (30.4 wt%), semi-coke (39.6 wt%), non-condensable gas-phase compounds (26.5 wt%), and bitumen (3.5 wt%). The pyrolysis process was conducted at a temperature of 650 ° C and with a steam flow rate of 150 kg/h. Liquid hydrocarbons were considered a target product. Comprehensive studies of their physicochemical characteristics, atomization process, droplet ignition, and combustion were carried out. The studied sample had physicochemical characteristics similar to traditional fuel oil (calorific value—42.6 MJ/kg, sulfur content—0.8 wt%). The jet spraying angle was 25° in view of the improved rheological properties of the test sample, with a homogeneous jet structure and a predominant droplet diameter of no more than 0.4 mm. The flame combustion process was accompanied by the formation of microexplosions, the frequency and intensity of which depended on the temperature of the air (Tg = 450–700 °C). This study, in view of its applied nature, is of interest in the design of new installations and technological systems for hydrocarbon pyrolysis.

The application of plasma process is growing field covering a wide range of activities, from welding technology, coating technology, deposition technology, manufacturing technology of metal powder, and other important engineering technology. The manufacture of metal powders can be generated from the process of gas atomization, water atomization, plasma atomization, and plasma rotating electrodes process atomization. In the process of plasma atomization provides advantages in addition to producing round powder, it is also very potential for efficient processing and recycling of used and alloy materials, thus saving fuel and essential materials. These operations will have a continuing impact on our industrial society as a whole. The industry of future metal powder manufacturers that utilize plasma atomization technology is an investment strategy that has a great opportunity to grow rapidly. A variety of plasma processes for the manufacture of metal powders will be reviewed in this paper, among others, are plasma atomization and plasma rotating electrodes process atomization. They are all potentially able to control and to produce of metal powders of spherical particles, making it very profitable on powder technology applications. The purpose of this review is to summarize and provide future research for activities in the field of metal powders by plasma atomization processes. The emphasis on plasma engineering technology future research in powder making available for exploration and research needs to be met so that these future research can be realized. Finally, the future challenges of automation from the use of plasma atomization technology for additives manufacturing, powder welding and medical manufacturing.
