15 Μαΐ 2016 · Calorific value and compositional ultimate analysis with a case study of a Texas lignite. May 15, 2016. Measurements to determine coal quality as fuel include proximate analysis, ultimate analysis and calorific value.
15 Μαΐ 2016 · Mapping of coal quality using stochastic simulation and isometric logratio transformation with an application to a Texas lignite. International Journal of Coal Geology, 152, 80–93. View Abstract
3 Ιαν 2022 · Thus, we will study the lignite coal (denoted Hambach, HA coal) and bituminous coal (denoted BA coal). The aromatic and aliphatic nature of a coal can be evaluated by solid NMR spectroscopy, which was applied to the two coals in this study: the (HA/BA) Aliphatic and (HA/BA) Aromatic ratios were found to be 1.52 and 0.65, respectively.
24 Ιουν 2020 · The distinguishing of high- and low-quality lignite coal with high performance will benefit the investor while also benefiting lignite coal users in terms of health. The highlights of the proposed method in this article are as follows.
Owing to the advantages of burning low-quality coal (coal slime and coal gangue), furnace desulfurisation, low [inline-formula] emission and deep load adjustment, the circulating fluidised bed ...
Statistical analysis of chemical data on Texas Eocene coals revealed startigraphic and geographic trends in lignite quality. Chemical data on near-surface coals wre obtained from various private and public sources. Seams from deep-basin coals were compared.
