24 Ιουν 2020 · Problem Statement. Lignite is one of the most important energy sources. An important problem in the economic and technical evaluation of lignite reserves is to measure lignite quality. The quality of lignite depends on parameters such as moisture, ash, sulfur, and calorific.
1 Σεπ 2021 · This work discusses the three most commonly used methods for analyzing lignite pores: nitrogen adsorption, mercury intrusion porosimetry (MIP), and nuclear magnetic resonance (NMR).
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
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...
We established a pulsed fluidized bed system to dry and concurrently separate fine lignite (−6 + 3 and −3 + 1 mm lignite). The kinetics and evaporation of lignite moisture were investigated in the pulsed air flow.
1 Μαΐ 2016 · To tackle these problems, this paper investigates the application of Gaussian co-simulation for modeling the cross-correlated compositional data in order to recognize the multivariate geochemical...
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.
