High-concentration coal–water slurry from Indian coals using newly developed additives

Combustion, performance and emission of a diesel engine fuelled with diesel doped with carbon black

“…The engine (1) was coupled to an electrical dynamometer (2) and a load cell (3). The desired load is provided to the engine with the help of the dynamometer.…”

“…Many investigations were carried out in several countries on the utilisation of coal slurry fuels, especially COS (coal-oil solutions), CWS (coalwater slurry) and charcoal water slurry in medium diesel engines [2]. The CWS seemed to offer a long-term alternative to fuel oil, and it is also conceived as an attractive fuel for power generation in India [3]. The use of CWS fuels in modified IC engines was proposed as one of the promising alternatives [4,5].…”

The utilization of sewage sludge by blending with coal water slurry

“…This coal-sludge slurry (CSS), much like coal-water slurry (CWS), can be pumped, transported in pipelines and combusted in industrial boilers and furnaces with an environmentally benign manner [15][16][17][18][19][20]. Using this method, heavy metals in the sewage sludge are trapped in ash during the fusion of coal ash, avoiding secondary pollution.…”

Study on Enhancing the Slurry Performance of Coal–Water Slurry Prepared with Low-Rank Coal

“…[16] Das et al [13] modulated three varieties of noncoking coal (low-rank Indian coal) using three starch-based additives, and obtained a highly concentrated coal-water slurry with low viscosity. Tiwari et al [17] obtained a high concentration CWS, which was up to 69% of coal loading, from Indian coals using the newly developed naphthalenetoluene-based additive. Aktaş et al [10] prepared CWS of up to 60% solids with a low-rank British coal in the presence of a non-ionic surfactant, Triton X-405.…”
