Combustion of coal water slurry-technology enabling the achievement of a reduced technical minimum of the boiler [PDF]

E3S Web of Conferences, 2019
The idea of combustion of suspended fuels was developed in the 1980s. The largest producer and user of slurry fuels (Coal Water Slurry, CWS) is China [3]. Despite of several decades of CWS research history, investigations are still carried out to improve

Incidental phosphorus and nitrogen loss from grassland plots receiving chemically amended dairy cattle slurry [PDF]

, 2012
peer-reviewedChemical amendment of dairy cattle slurry has been shown to effectively reduce incidental phosphorus (P) losses in runoff; however, the effects of amendments on incidental nitrogen (N) losses are not as well documented. This study examined P

Insight of anode reaction for CWS (coal water slurry) electrolysis for hydrogen production [PDF]

, 2016
Mechanism of CWS (coal water slurry) electrolysis was investigated by using anode reaction kinetics. The results indicated that the activation energies of electrode reaction reduce with the increase in activity of carbon materials.
