    <ns1:description language="sr">Predmet istraživanja ove doktorske disertacije su metode za istovremeno merenje temperaturnog profila plamena, položaja termalnog fokusa i koeficijenta prigušenja u ložištu kotla termoelektrane na ugalj. Opisan je novi merni postupak koji zajedno sa konstruisanim instrumentom za merenje temperature, predstavlja posebnu vrstu bezkontaktne metode. Novi instrument koji je korišćen u tu svrhu, predstavlja specijalan uređaj koji se zasniva na dvobojnom pirometru. Pirometar je u produžetku spojen sa dugačkom cevi koja ima poseban sistem hlađenja vodom, zbog čega je moguće izvršiti direktna merenja karakteristika plamena duboko u unutrašnjosti kotla. Na taj način su u svakom trenutku procesa sagorevanja dostupni podaci o temperaturnoj raspodeli, maksimalnoj i minimalnoj temperaturi, položaju termalnog fokusa, kao i vrednosti koeficijenta prigušenja...</ns1:description>
    <ns1:description language="en">The objectives of the research of this doctoral dissertation are the methods for the simultaneous measurement of the temperature profile of the flame, the position of the thermal focus and the absorption coefficient in the coal-fired boiler of the thermal power plant. A new measuring procedure is described which, together with the constructed temperature measurement instrument, is a special type of contactless method. The new instrument used for this purpose is a device based on a two-color pyrometer. The pyrometer is connected in the extension with a long tube that has a water cooling system This enables direct measurements of the flame characteristics deep inside the boiler. Thus at each stage of the combustion process, temperature distribution data, maximum and minimum temperature, the position of the thermal focus, as well as values of the coefficient of attenuation are available...</ns1:description>
