THERMODYNAMIC CALCULATION OF STEAM GENERATOR DURING REPLACING OF FUEL OIL WITH NATURAL GAS

Djelatnosti koje se bave proizvodnjom energije, a samim time i generatori pare koji služe za proizvodnju pare, znatno utječu na povećanje emisija stakleničkih plinova. U diplomskom radu je izvršen proračun dva generatora pare. Generatori imaju jednake dimenzije, ali je pogonsko gorivo različito. Jedan koristi loživo ulje, a drugi prirodni plin. Proračuni su napravljeni sa svrhom da se vidi razlika u emisiji dimnih plinova te iskoristivost samih generatora pare. Generator pare na loživo ulje proizvodi nešto više ugljikovog dioksida i sumporovih oksida, dok generator pare sa prirodnim plinom proizvede više vodene pare i dušikovih oksida.Energy production activities, and thus steam generators used for steam production, have a significant impact on increasing greenhouse gas emissions. In the diploma thesis, the calculation of two steam generators was performed. The generators have the same dimensions, but the fuel is different. One uses fuel oil and the other natural gas. The calculations were made in order to see the difference in flue gas emissions and the efficiency of the steam generators themselves. A fuel oil steam generator produces slightly more carbon dioxide and sulfur oxides, while a natural gas steam generator produces more water vapor and nitrogen oxides
