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: 1.5 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: 1 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: 0.3 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: 0.00017 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: 0.28 SJR: 0.279 SNIP: 0.544 CiteScore™:: 2.5 H-Index: 22

RESUMO

Numerical simulation is performed to investigate NO reduction in pulverized coal combustion by adding co-flow methane as secondary fuel. Addition of methane can reduce overall NO by reducing the Fuel NO and by considering it as re-burn fuel as well. In general, re-burn fuel is injected downstream of the flame. We injected co-flow methane, primary air, and coal from the same plane of an axi-symmetric burner. Moreover, in all simulations, we kept the heat output constant (5 kW) for different blend conditions. The study revealed that a large quantity of NO forms within the domain, when only coal is used as fuel. With the reduction in coal and addition of methane, the total NO formation within the domain is reduced significantly. It is also observed that too great addition of methane increases the flame temperature, which increases the thermal NO and prompt NO as well. Higher flame temperature enhances the re-burn rate, thus overall NO decreases. A better coal burnt out has been observed with same conditions due to greater flame temperature.
