The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

SINOPSIS

The theoretical model of porous carbonized particle combustion in air is discussed. The model considers equations of heat and mass transfer in the gas phase and inside porous particles. The heat flux from the particles surface to the wall of the furnace is taken into account. The different regimes of particle combustion are investigated. It is shown that the gas-phase regime of particles combustion, in which the heterogeneous chemical reaction of carbon interaction with oxygen is absent and the homogeneous chemical reaction occurs above particle surface, is realized when the furnace walls temperature is rather high. In this regime of the particle combustion the heterogeneous chemical reaction of carbon interaction with carbon dioxide takes place inside particle, because the oxygen is almost totally supplied in homogeneous chemical reaction above the particle surface. For lower furnace wall temperature the kinetic regime of particle combustion, in which the heterogeneous chemical reaction of carbon interaction with oxygen as well as with carbon dioxide takes place inside porous particle, is observed. In the kinetic regime of the particle combustion the rate of the particle burning out is increased with furnace wall temperature increasing and that practically achieves the maximum particle burning out rate in the diffusing regime of particle combustion. In the gas-phase regime of the particle combustion the rate of the particle burning out is smoothly increased achieving the maximum rate of the particle combustion at the very high furnace wall temperature. Thus, there is some crisis of the particle burning out rate, when the rate of the particle burning out is very sharply fallen down in the narrow range of the furnace wall temperature (from 1300 K to 1400 K for particle having size about 100 μm and burning out in air).
