DISTRIBUTION OF TRACE ELEMENTS AT BITUMINOUS COAL AND LIGNITE COMBUSTION AT CIRCULATING FLUIDISED-BED POWER STATIONS

摘要

The paper is focused on study of the redistribution of trace elements between bottom ash,fly ash and emissions at two Czech fluidised-bed power stations,where bituminous coal and lignite were combusted at two boiler outputs.Theoretically calculated amounts of the elements released into atmosphere were compared with emission limits.
