15 Ιαν 2024 · To accomplish the goals, 7430 data points containing ten coal features, such as ash, moisture, fixed carbon, volatile matter, hydrogen, carbon, sulfur, nitrogen, oxygen, and GCV are selected from the U.S. Geological Survey Coal Quality (COALQUAL) database.
24 Ιουν 2020 · One of the most important practical problems in lignite mining is to make a lignite quality classification due to heterogeneity. The quality of lignite depends on the parameters such as moisture, ash, sulfur, and calorific value and an acceptable, reliable classification mechanism is required.
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.
A sensitivity analysis on co-firing of local biomass and Ekibastuz coal demonstrated the optimal operating temperature for fluidized bed reactor at 1148 K with the recommended biomass-to-coal...
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
1 Μαΐ 2016 · Drill hole datasets ranging from widespread exploration drilling to detailed development drilling from a lignite deposit in Texas were used to illustrate the modeling.
The heat content of subbituminous coal ranges from 17 to 24 million Btu per ton on a moist, mineral-matter-free basis. ANALYSIS CONSIDERATIONS 3. Lignite is the lowest rank of coal, often referred to as brown coal, used almost exclusively as fuel for steam-electric power generation.
