1 Οκτ 2023 · Ash content is one of the most critical indicators for evaluating coal quality in coal preparation plants. The conventional methods of ash content determination take at least 2 h and involve a series of procedures, including manual sampling, sampling preparation, drying, weighing, and incinerating.
18 Δεκ 2021 · Ash content is a key evaluation parameter of coal quality, as well as a standard that guides the reasonable utilization of coal. The conventional ash content measurement is to heat the coal in muffle furnace at a temperature higher than 800 °C, which causes high consumption of energy and time.
15 Απρ 2024 · In this study, an innovative approach that integrates SHapley Additive exPlanations with a deep learning model Tabular Networks has been introduced, which efficiently predict the ash content by employing the compositional data obtained from rapid elemental analysis.
1 Μαρ 2011 · The ash content of the biomass fuels studied, with the exception of paper sludge (ash content 51%), ranged from 0.2% to 6.6% and was lower as compared to that of the coals. The origin of agricultural and forest residue ashes was mostly inherent and their composition was dominated by Si, Ca, K and P inorganic species.
23 Μαΐ 2024 · Leaching tests showed that coal ash leachates had higher concentrations of environmental pollutants, such as As, Cd, Co, Mn, Mo, Sb, and U, than patent fuel leachates. Adding patent fuel to coal affects combustion, ash properties, emissions, and disposal.
28 Νοε 2019 · Ash content has paramount importance for the identification of a particular lignite’s quality. Among the methods used for on-line content determination, efforts covering the ash content estimation at the processed particle size ranges and ensuring fast responses are more favorable.
Due to the trace element content in coal ash, there is interest in assessing (1) the properties and behavior of coal ash and its constituent trace elements in various environments, (2) the potential for human exposure, and (3) the potential for extracting elements of interest for reuse in various industries.
