INVESTIGATION OF THE EFFECT OF PARTICLE SIZE OF LIMESTONE ADDED TO LIGNITE ON EMISSION BEHAVIOUR IN A FLUIDIZED BED COMBUSTION SYSTEM

Abstract

ABSTRACT

In the experimental studies, KÜtahya Tunçbilek Lignite was used as fuel, silica sand and ash mixture was used as bed material, limestone from GÖynÜk was used as adsorbent. For the combustion system particle size of coal and limestone were calculated employing the cumulative method and optimum particle sizes for the system were determined. Adding limestone to the coal, effect of particle size on the emission behaviour was investigated. Separately optimum operating conditions were determined on the basis of pollutant emissions for different coal and adsorbent properties. These conditions are described as regions there the combustion performance is not hindered and  there the efficiencies in combustion and SO2 adsorption are kept high.
