10 Numerical combustion of aviation fuel part I: a cross-model comparison of n-heptane premixed flameFour different n-heptane mechanisms were used to simulate a fuel rich n-heptane premixed flame and their results were compared with experimental measurements. In addition to discussion of the numerical performance of each mechanism, flux analysis coupled with the atomic distribution technique was us...Aviation fuel; n-heptane; Premixed flame2003
11 Final Report Geothermal Battery Energy StorageSolar and wind power are being introduced into electric grids to supplement and replace conventional electricity production. The deployment of utility-scale storage has not kept pace to overcome the intermittent nature of solar and to a lesser extent wind. Large-scale energy storage is cur...2020-06

13 Carbon dioxide effects on metal vaporization during coal combustionCoal combustion products may take one of two forms. Residual ash (> 1 micron) is formed by particle shrinkage and breaking during combustion. Some material will vaporize and later recondense. During recondensation, these molecules have a high affinity for submicron particles because of the large sur...Coal combustion products; Metal vaporization; Carbon dioxide; Residual ash2001
14 Pulverized coal combustion: NOx formation mechanisms under fuel rich and staged combustion conditionsA 2 Kg/h pulverized fuel one dimensional flame combustor was used to determine time resolved NO profiles under fuel rich and staged combustion conditions. Seven solid fuels, including two coal chars, were investigated. Results show that at all fuel rich conditions NO is formed rapidly and then is ...Flame; Composition; Reaction1979
15 Pulverized coal combustion: the influence of flame temperature and coal composition on thermal and fuel NOxA laboratory combustor was used to investigate the factors that influence the conversion of fuel nitrogen in coal during coal combustion.
