The results, given in graphical form, were obtained with calculations of the combustion for two gaseous fuel types (natural gas and a mixture of gases) in industrial conditions. Analysing the different curves has made it possible to compare the combustion conditions for two gaseous fuels of different heating values and to describe the influence of changes in excess air ratio values, air preheated temperature and oxygen content of the combustion air on the flame temperatureAnaliziran je vpliv predgrevanja in obogatitve zgorevnega zraka na temperaturo plamena kot parametra ogrevanja jekla. Rezultati, ki so predstavljeni, so bili pridobljeni z analitičnim izračunom procesa zgorevanja za dve vrsti plinastega goriva (naravni plin in mešanica plinov) v industrijskih razmerah. Analiza odvisnosti je omogočila primerjavo pogojev zgorevanja dveh plinastih goriv z različno vrednostjo in vpliv prebitka zraka, temperature predgrevanja zraka in vsebnosti kisika v zraku na temperaturo plamenaTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
