Opis:: Mercury emission field measurements were conducted for two types of coal from Polish mines. Total mercury content were evaluated in coal and ash on mercury analyzer atomic absorption spectrometer AMA 254. Obtained result shows that brown coal contains more mercury compared to hard coal (289 ppb and 66 ppb respectively for a polydisperse system). Mercury concentration in ashes is several times higher than for coal which means ash may be a good absorber for mercury. Also, application of oxy-fuel technology results in smaller amount of mercury absorbed in the ash which can be related to higher emission of Hg in the gaseous form.

Opis:: Experimental investigations and numerical simulations have been conducted in this study to derive and test the values of kinetic parameters describing oxidation and gasification reactions between char carbon and O2 and CO2 occurring at standard air and oxy-fuel combustion conditions. Experiments were carried out in an electrically heated drop-tube at heating rates comparable to fullscale pulverized fuel combustion chambers. Values of the kinetic parameters, obtained by minimization of the difference between the experimental and modeled values of char burnout, have been derived and CFD simulations reproducing the experimental conditions of the drop tube furnace confirmed proper agreement between numerical and experimental char burnout.
