ABSTRACT
Syrian fuel oil is most common of its contents of sulphur and vanadium,i.e 4.5% and 120 ppmrespectively and during its combustion, sulphur will be converted to sulphur dioxide SO2. in someof the boiler parts such as superheater , reheater and air heaters, some of the sulphur dioxide willbe catalyzed by Vanadium to sulphur trioxide SO3. In both cases this causes severe corrosion anddeposits in addition to air pollution. To meet stringent emission standards stipulated by regulatoryagencies, fuel oil is required to bring down its content of sulphur or it must be treated during itscombustion. the present work aims to highlight the side effects caused by fuel oil combustion inaddition to investigate the influence of special types of chemical additives in order to reduce theseeffects. solids contents (ash, soot, cenosphere) as well as gas emissions produced from ZaraThermal Power Station (ZTPS), which is operated using fuel oil or sometime nature gas,have beendetermined. The station consists of three units with maximum capacity of 660MW. The resulltsshow that the station produces about 15 ton SO2/hr and about 4 ton solids/day in addition tocorrosion problems at several parts of the boiler and chimney. By utilizating continuouscombustion-unit and fuel oil as fuel to this unit, we could apply several chemical additives such asCu, Mn, Mn+Cr and Mn+Cu+Cr at different concentrations of 100,175 and 250 ppm. There wereworth noting results of using these additives in reducing gas emissions (SOx, CO ).
