Combustion kinetics of coal chars in oxygen-enriched environments
Oxygen-enhanced and oxygen-fired pulverized coal combustion is actively being investigated to achieve emission reductions and reductions in flue gas cleanup costs, as well as for coal-bed methane and enhanced oil recovery applications. To fully understand the results of pilot scale tests and to accurately predict scale-up performance through CFD modeling, accurate rate expressions are needed to...
متن کاملCoal Desulfurization by Solvent Leaching Methods
Coal desulfurization prior to usage is a preprocessing in order to achieve clean fuel and reduce environmental impacts such as acid rain. Desulfurization of Lakhra (Pakistan) coal was conducted with different solvents. Coal was leached with different solvents like hot water, H2O2/H2SO4 and HNO3. It was found that the effects of the leaching temperature, agitation time and particle size on the r...
متن کاملMercury from Coal Combustion
A 1997 study in Minnesota indicated a relationship between mercury deposition trends and regional coal combustion (as well as other possible sources) spanning a period of two centuries (Engstrom and Swain 1997). Sediment core sampling from rural lakes in eastern Minnesota indicated a growth in mercury deposited from the air since the first half of the 1800s, with the amount peaking in the 1960s...
