Show engineering will be harder. Whether there is time efficiency for self developing or not, understanding of technology development at present stage is absolutely necessary. Regarding FGD market in Taiwan, other than TPC, coal fired boilers for cogeneration have the highest market potential; while it may not able to work out the large scale FGD system in coal fired power plant of TPC without long term successive R&D, boilers for cogeneration ( ca. 120TIHr ) will be our first object in establishing domestic technology. FGD system is equivalent to a chemical plant, in view of our plant constructing and working abilities, except of few apparatus, material and parts used in FGD systems, which need import in, most parts of FGD system can be made by domestic companies, and the only deficiency is the ability of system planning and designing, which is also the primary object of devotion of ERlJITRI into R&D of FGD technology. In the study of O.IMWe Pilot Scale wet FGD system by using limestone as absorbent, under normal operation conditions, S02 removing capability higher than 90% has been achieved,and relationship examinations of major influential factors have also preliminarily finished. Application tests of various additives, prevention of scale accumulation and clogging, as well as utilization and treatment of by-products are continued to carry out in order to mature FGD technology, so as to provide assistances in setting up FGD system and services of supplying related technical informations for industries, and to work together for cleaning our atmosphere.
