“…We have incorporated into our recently proposed correlation [10] (based on more than 300 experiments for O 2 , CO 2 , CO and/or N 2 environments) water vapor results (pure and blended environments) which corresponds to around 30 additional data points, half of which is pure steam. The modified correlation from [10] (solid lines called ICARE in Figure 2) fits our current results well. The combustion time (𝑡 𝑏 ) is expressed as (with units: atm-K-ms-µm):…”

“…According to estimates, for a layered combustion process, there are significant opportunities to intensify the combustion of solid fuels (Ermakov, 2005;Kamenetsky, 2010). In this case, the intensity of combustion on the surface of coal particles in the flare process approaches its limit physically (Braconnier et al, 2020). Layer burning of coal allows maximum retention and capture of solid coarse and fine fractions of slag and ash particles within the boiler on a grate (Ermakov, 2005;Kamenetskii, 2006;Kamenetskii, 2013a;Bao et al, 2020).…”

Experience shows that the trend towards using solid fuels in the energy sector of Kazakhstan will be implemented for a rather long time. At the same time, the global trend is currently tightening environmental requirements. They set the task to continue improving coal combustion efficiency and minimize emissions of harmful substances and greenhouse gases into the atmosphere. This article aims to conduct complex thermal engineering tests of the KCVr-0.43 hot water boiler. For this, the following measurement and control tools were used: the standard boiler room secondary devices, an industrial gas analyzer Testo-350, a control (reading) module Testo-454 with temperature probes and a Pitot tube, a soot number meter Testo-308, a temperature meter 2TPM1, a portable liquid flow meter Vzlet-PRC and a stopwatch. All they had valid verification and calibration certificates. An analysis of the gas composition and technical parameters of the KCVr-0.43 hot water boiler in the investigated operation mode with Shubarkul coal during a long-term test showed that it seems possible to operate boilers of this series under low load conditions without boosting air and fuel. They can reduce emissions of toxic NOx and greenhouse gases CO2 into the atmosphere. In this case, burning Shubarkul coal without forcing through the air is characterized by significant carbon monoxide CO emissions. The formed nitrogen oxides NOx decompose in reactions with CO with the formation of molecular nitrogen and oxygen. Burning, coke residue in the layer, coal-burning stages, emissions of harmful substances.

“…Few data are then available from the literature in such conditions. Most of the time, the environment is reproduced in academic facilities using a stream of monodisperse, freely falling and burning droplets using laser ignition technique [7] [8], levitating droplets [9] or solid-propellant flames from small samples [10] [11]. The particles burning time is the main studied data in most studies, which is limited for fine model adjustments.…”

Aluminum-droplet combustion is studied in solid-propellant flame environment at 1.0 MPa. Al vapor is observed during the combustion process with high-speed Al-PLIF and visible-emission images. A onedimensional quasi-steady model of aluminum combustion is used to simulate Al-atom concentration and temperature profiles around the droplet. Al-PLIF image simulation has been developed to generate synthetic fluorescence images that reproduce the experimental images. A comparison approach is initiated between experimental and numerical Al-PLIF images and applied to the study of a specific droplet observed during the experiments with a diameter larger than 120 µm. A reasonable consistency is observed between simulated and experimental data, which is promising to provide validation data for the development of more representative aluminum-combustion models.
