    It seems that increasing amount of heavy metals is transfered to fly ash under higher gas flow rates, as effect of particle attrition and entrainment from the FB. The experimental results suggest that for efficient combustion of dried sewage sludge in static or circulating fluidized bed the temperature should be higher than 850°C.

    Emise těžkých kovů jsou ovlivňovány otěrem a únosem jemných částic z fluidní vrstvy. Teplota spalování by měla být vyšší než 850 oC.
