ABSTRAKEnergi merupakan kebutuhan pada kehidupan manusia. Sumber energi fossil yang digunakan untuk memenuhi kebutuhan energi semakin lama semakin menipis. Sehingga diperlukan sumber energi alternatif atau peningkatan efisiensi dalam pemanfaatan energi. Panas buang merupakan salah satu sumber energi alternatif. Pemanfaatan panas buang salah satunya adalah dengan menggunakan siklus rankine organik. PLTU memiliki panas buang yang berpotensi untuk dimanfaatkan. Temperatur gas buang pada PLTU yang rata-rata sebesar 150 oC. Proses perancangan dilakukan untuk memanfaatkan panas buang hasil pembakaran. Hasil perancangan sistem siklus rankine organik mampu menghasilkan daya sebesar 6053 kW (R142b), 5705 kW (R123), dan 5502 (Isopentane) serta efisiensi sebesar 18.54%, 18.51%, dan 17.85% untuk fluida kerja R142b, R123, dan Isopentane.Kata kunci: siklus rankine organik, gas buang, panas sisa ABSTRACTEnergy is needeed for human life. Fossil energy which used to fulfill our needs is diminished. So, alternative energy source is used. Waste heat are one of a kind energy alternative source. Organic rankine cycle can be used to utilitze waste heat. Coal power plant which have flue gas to utilized. Average flue gas temperature in coal power plant are 150 oC. Design process to utilize waste heat has been conducted. The power produced in the system are 6053 kW, 5705 kW, and 5502 kWalso the efficiency are 18.54%, 18,51%, and 17,85% for working fluid R142b, R123, and Isopentane respectively.Keyword: organic rankine cycle, waste heat, flue gas

Abstract Tightening of norms for air protection leads to a development of new and significantly more effective techniques for removing particulate matter, SOx and NOx from flue gas which originates from large solid fuel combustion. Recently, it has been found that combinations of these environmental technologies can also lead to the reduction of mercury emissions from coal power plants. Now the greatest attention is paid especially to the coal power plant in Opatovice nad Labem, close to Hradec Kralove. Its system for flue gas dedusting was replaced by a modern type of cloth fabric filter with the highest particle separation efficiency which belongs to the category of BAT. Using this technology, together with modernization of the desulphurisation device and increasing of nitrogen oxides removal efficiency, leads also to a reduction of mercury emissions from this power plant. The University of Hradec Kralove, the Opole University and EMPLA Hradec Kralove successfully cooperate in the field of toxic metals biomonitoring almost 20 years. In the Czech-Polish border region, comprehensive biomonitoring of mercury in bioindicators Xerocomus badius in 9 long-term monitored reference points is done. The values of mercury concentration measured in 2012 and 2016 were compared with values computed by a dispersion model SYMOS′97 (updated 2014). Thanks to modern methods of dedusting and desulphurisation, emissions of mercury from this large coal power plant are now smaller than before and that the downward trends continues. The results indicate that Xerocomus badius is a suitable bioindicator for a long-term monitoring of changes in mercury imissions in this forested border region. This finding is significant because it shows that this region is suitable for leisure, recreation, and rehabilitation.

The effects of different additives including MgSO4, MnSO4, adipic acid, citric acid, benzoic acid, succinic acid and acrylic acid on SO2 removal from a limestone-gypsum wet flue gas desulfurization (FGD) system and gypsum characteristics were investigated. An optimized formulation additive for simultaneously improving flue gas desulfurization efficiency and gypsum quality was found out. This formulation additive was successfully applied in an industrial scale FGD system of a local coal-power plant (600 MW, Shanghai Wujing Power plant, China), and the gypsum quality was improved. The optimized formulation additive was acrylic acid, MnSO4 and citric acid mixed at a ratio of 1:1:2, which can simultaneously achieve an increased desulfurization efficiency of 97.02% and a low gypsum moisture content of 4.32%. Moreover, MnSO4 and acrylic acid were found to be most effective for improving SO2 removal, and citric acid contributed to gypsum particles with more uniform sizes and regular shapes, as well as good dewatering characteristics.
