    Abstract Text Rezime U radu je izvršeno poređenje stare drvene i nove PVC ispune ugrađene pri rekonstrukciji druge faze rashladnih tornjeva broj 16 i 18 trećeg bloka TE Kolubara A. Blok tri rashladne kule (16, 17 i 18) je gašenjem RK br. 17, zamenjen sa dve kule. Pored adekvatnih termodinamičkih karakteristika izabrana ispuna je morala zadovoljiti kriterijume vezane za samoispiranje zbog lošeg kvaliteta rashladne vode i opasnosti od zagušenja. Perforacija ispune i veličina kanala je takva da obezbeđuje dobre termodinamičke i strujne karakteristike uz samoispiranje. Projektom rekonstrukcije rashladni kapacitet dve rashladne kule je povećan tako da zamenjuje dosadašnje rešenje sa tri rashladne kule u bloku. Protok vode kroz rashladnu kulu je povećan za 50%. Iako je hidrauličko opterećenje rashladne kule povećano, strujne karakteristike ispune su takve da je pad pritiska koji ventilator treba da savlada smanjen. S obzirom da se ukupan protok vode u sistemu nije promenio hidraulične pumpe rade u istom režimu kao i ranije. Gašenjem srednje kule i ugradnjom pomenute ispune u preostale dve kule bloka ostvaren je potreban rashladni kapacitet uz uštedu u energiji i održavanju. Abstract Comparison of old wooden and reconstruction replacement PVC fill of second phase cooling towers no. 16 and 18 in the third thermoblock of Thermopower plant Kolubara A have been done in this paper. Group of three cooling towers (16, 17 and 18) is replaced with two by shuting down of cooling tower number 17. Beside adequate thermodynamic properties, chosen fill had to meet antifouling criteriums due poor water quality and danger of flow obstruction. Fill perforation and chanel size provide good thermodynamic, flow and antifouling characteristics. Cooling capacity of two cooling towers have been increased in order to replace former block of three cooling towers. Water flow through cooling tower is increased by 50%. Despite increase of hydraulic load, due to fill flow characteristics pressure drop that fan have to overcome is reduced. Unchanged water flow through system provided hydraulic pumps to remain in the same regime as before. Required cooling capacity is obtained together with energy and maintenance savings by turning off of the middle cooling tower and using mentioned fill in remaining two towers of the block. « hide
