UTILIZATION OF MECHANICAL ACTIVATED WASTE FROM SEMI-DRYDESULPHURIZATION INSTALLATION IN FLUIDIZED BED BOILERS-ONEMONTH TEST

摘要

Abstract - The paper presents results of industrial utilisation of waste from the prcoss of semi – dry flue gasrndesulphurisation in a fluidised bed boiler. By products from the EC Siekierki combined heat and power plantrnwas mixed in 50 / 50 proportion with calcium carbonate, traditionally used in the flue gas desulphurisationrnpr℃ess in the CFB 450 boilers. The mixture was then mechanically activated and blew into the boiler through arnflue gas desulphurisation installation. The following results were obtained: calcium sulphite was fully utilisedrnand converted into sulphate and the flux of sorbent applied was reduced by about 30%. Moreover, boilerrnefficiency increase was observed as a result of incomplete and imperfect combustion loss decrease. The testrnlasted one month.
