Cleaning of hot calciner exhaust gas by low-density ceramic filters

Efficient dust removal at high temperatures gains increasing interest and c eramic filters are suitable to achieve high collection efficiencies for (su b-)micron particles. The paper presents experimental results for their appl ication in lime-kiln operations. Experimental results were transformed into design equations for (i) the baseline pressure drop and the effect of the cleaning cycles; (ii) the total pressure drop and the effect of the dust lo ad; (iii) the prediction of the time between two cleaning cycles in functio n of the operating parameters.
