Coal product moisture control using stockpiles
(Springer, 2016)The moisture content of product coal is a major factor influencing the efficiency of downstream coal utilization processes. Product stockpiles are often used as a control measure to regulate the moisture content of the ... -
Development and manufacturing of a prototype pulverized fuel feeder for a micro burner
(North-West University (South Africa) , Potchefstroom Campus, 2017)Existing coal fired power stations could be improved by increasing the efficiency of the combustion process. The combustion process is incorrectly set up since inaccurate calorific values (CV) for the pulverized fuel is ... -
Drying of coal fines assisted by ceramic sorbents
(Springer, 2016)It is proposed to introduce contact sorption drying as a method to reduce the moisture content in coal fines. The aim of this study was to investigate the possibility of drying fine and ultra-fine coal using porous ceramic ... -
Effect of moisture content, temperature and exposure time on the physical stability of chitosan powder and tablets
(Taylor & Francis, 2014)Context: Chitosan does not rank highly regarding its employment as tablet filler due to certain limitations. Undesirable properties that limit its utilization as excipient in solid dosage forms include its hydration ... -
The effect of temperature and moisture on the amorphous-to-crystalline transformation of stavudine
(Elsevier, 2009)Stavudine is a nucleoside reverse transcriptase inhibitor active against HIV, and is known to exist in two polymorphic forms designated as forms I and II, and a hydrate form III. An amorphous solid of stavudine was ... -
Effects of Temperature and Moisture on the Ecotoxicity of Metal-Based Fungicides Towards Earthworms
(North-West University (South Africa), 2022)Climate change is a major threat to biotic and abiotic ecosystems worldwide and might potentially affect the mobility and bioavailability of metals in soil. Anthropogenic activities such as mining, agriculture and the use ... -
Influence of moisture on the resistivity of selected South African fly ashes
(North-West University (South-Africa). Potchefstroom Campus, 2019)The coals fired in the pulverised fuel boilers of South African power stations are generally of poor quality, producing numerous emissions, of which particulate matter has the largest impact in South Africa. Recently, the ... -

Moisture adsorption and desorption characteristics of some South African coals
(SAIMM, 2013)The high final total moisture content of fine coal after mining and processing is one of the major reasons that this resource is not extensively used in subsequent power generation, combustion, or other conversion processes. ... -
Validation of using a modified BET model to predict the moisture adsorption behavior of bituminous coal
(Taylor & Francis, 2016)A good correlation exists between the amount of moisture adsorbed and the oxygen content of medium-rank B vitrinite-rich and medium-rank C inertinite-rich bituminous coal. Total mass moisture adsorbed per gram of coal ...
