Abstract
Termoelektrane predstavljaju vec´inske proizvod¯acˇe elektricˇne energije u svetu, što za posledicu ima stalne pokušaje unapred¯enja u vidu smanjenja štetnih uticaja na životnu sredinu uz pove´canje efikasnosti, raspoloživosti i prihoda. Pomenuti efekti su u direktnoj vezi sa procesom sagorevanja, zbog ˇcega su upravljanje i optimizacija ovog procesa od suštinskog znaˇcaja. Ove potrebe su ˇcesto ograniˇcene mogu´cnostima nadgledanja procesa sagorevanja. Obiˇcno se za sagledavanje ovog procesa analizira neko od dostupnih merenja dobijenih iz hemijskih analizatora sadržaja ugljen-monoksida ili kiseonika u dimnim gasovima, što je korisno za ocenu kvaliteta sagorevanja fosilnih goriva. Med¯utim, ovo su globalni pokazatelji i ne govore ništa o lokalnoj raspodeli temperatura unutar ložišta...
Thermal power plants are the main producers of electrical energy in the world, and therefore there are constant attempts for improvement in terms of reducing harmful effects on the surroundings, while at the same time increasing eciency, availability and incomes. Aforementioned eects are directly related to the combustion process, which gives great importance to control and optimization of this process. These requirements are usually constrained by the possibilities of combustion process monitoring. This is mainly done by performing the acquisition of available measurements obtained from the chemical analysis of carbon dioxide and oxygen content in the flue gases, which is useful for the evaluation of fossil fuels combustion. However, these are only global indicators and they provide no information about the local temperature distribution inside the furnace...
