High-Temperature SHS Heat Insulators Based on Pre-Activated Mineral Raw Materials

open access: yesCrystals
In this paper, the results of the technological combustion of SHS heat insulators based on mineral origins are presented. It is shown that after mechanochemical treatment of minerals—diatomite—the kinetic characteristics of the combustion process change,

Effect of Mechanochemical Activation in the “Dust–Na2S” and “Dust–Na2S–NaOH” Systems on the Phase Transformations of Arsenic in Copper Smelting Dust

open access: yesMetals
Copper smelting dust is a heterogeneous by-product of pyrometallurgical processing containing sulfate- and arsenic-bearing components, which accounts for its high chemical stability and environmental hazard. In this context, mechanochemical activation is

A study on the relationship between vehicle operating conditions and NOx emission characteristics [PDF]

open access: yesE3S Web of Conferences
To address the challenges faced by vehicles during actual operation when passing through traffic lights or intersections, where rapid changes in operating conditions can lead to a decrease in SCR efficiency and an increase in NOx emissions, this study ...

Combustion noise

open access: yesProceedings of the Combustion Institute, 2015
AbstractCombustion noise is becoming increasingly important as a major noise source in aeroengines and ground based gas turbines. This is partially because advances in design have reduced the other noise sources, and partially because next generation combustion modes burn more unsteadily, resulting in increased external noise from the combustion.

Detailed analysis of iso-Pentanol combustion chemistry in flames

open access: yes, 2013
In this study, two flames of iso-pentanol were stabilized on a 60-mm flat flame burner at a low pressure of 15 Torr and analyzed by a flame-sampling molecular-beam setup coupled to a mass spectrometer (MBMS).
