Abstract
In this paper, results of fuel behavior during combustion of coal and alternative fuels in oxy-fuel atmosphere are presented. The objective of this work was to evaluate the dependencies between properties (ignition, explosion parameters, emissions of NOx and SO2) of coal and alternative fuels. The exchange of air for recycled flue gas and oxygen mixture, leads to changes of combustion behavior i.e. lower emission of NOx, SO2 and increased ignition delay time. Nevertheless, performed experiments do not indicate significant differences in explosion parameters among different fuels at air and 30%O2/70%CO2 atmosphere.
