The experimental investigation carried out allowed one to determine the infl uence of the source coal grade, oven medium temperature, and of the CWF drop size on time and temperature correlations characterizing the process of individual fuel drop combustion in static air. It has been established that shortening of the total time of CWF drops combustion related to the oven medium temperature increase and the drop size decrease is governed by a power function. In identical conditions, the time of CWF drops combustion is shortened signifi cantly, when anthracite is replaced by the brown source coal. The research and processing of the obtained experimental data allowed establishing empirical dependences of the CWF drop combustion time on volatile content in the source coal, and on drops sizes, taking into account the oven medium temperature and the source coal grade. It was found that in the equation describing the dependence of the combustion time on the drops sizes the exponent of the size is equal to 1.6 and does not depend on the coal grade and oven medium temperature.

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.

Under research, there is a combustion process of multicomponent coal-water fuel (CWF) that was conducted with mixing ratio of coal, pyrolysis, and technical water. The pyrolysis water was extracted through pyrolysis oil settling, where the oil was obtained from pyrolysis of wood waste. Ignition and combustion of CWF samples were carried out in a combustion chamber at heating medium temperatures (T g = 600-1000 C, with an interim step of 50 C). Gas-phase combustion products were analyzed with a flow-line gas analyzer. Technical water in CWF composition was replaced with pyrolysis one that was acted to raise the reactive capacity. It resulted in reducing the ignition delay time τ i (by an average of 25%) and the minimum ignition temperature T min i (from 440 С to 393 С, reliance on a CWF composition). In addition, increase in flame combustion time was recorded by an average of 20%, as well as dependence on a heating medium temperature and a CWF composition. In the case when a CWF liquid-phase component was completely replaced with the pyrolysis water, the significant increase in heat value by 2.14 MJ/kg was observed. According to the data of the flow-line gas analyzer, we concluded that the CWF combustion based on the pyrolysis water was accompanied by less NO x emission (by an average of 22%) but more CO and CO 2 amount (by an average of 1.4 and 1.2, respectively). It was found according to the results of the energy balance assessment that application of pyrolysis water in CWF composition leads to a decrease in fuel consumption for heat production by 16.7%.
