“…According to the results of studies [77][78][79], changes in the viscosity and density of the liquid affect the value of the jet spraying angle, its droplet size distribution, and range. These parameters will influence the rates of ignition and combustion of the slurries.…”

Spraying Characteristics of Alcohol‐Coal‐Water Slurries with Low Coal Content

et al. 2022

View full text Add to dashboard Cite

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.

“…At the same time, the q value differs significantly from the case when P f = 0.2 MPa/P a = 0.18 MPa. This is due to the fact that such pressure values for ACWF are critical (similar to [77]), and the q value will change slightly with a further increase in fuel and air pressure.…”

The use of internal combustion engines has become common in transportation, especially in aviation, one of which is the Cessna training aircraft with a piston engine. The effect of fuel injection pressure on injection temperature has been a focus of many studies because it has the potential to improve combustion efficiency. Increasing the fuel injection pressure in avgas causes an increase in injection temperature and also enhances temperature stability during injection.

“…In the image, the jet spraying angle is represented by red lines that indicate the jet boundaries. It is known [52] that spatial distribution of droplets and their size depend on geometric characteristics of the jet, including the spraying angle, which affects the conditions of ignition and combustion of sprayed fuels in the boiler furnaces. The experimental value of the jet spraying angle in the study area did not exceed 25 • .…”

Steam Pyrolysis of Oil Sludge for Energy-Valuable Products

et al. 2022

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.
