Methane fuel is burned with air in a boiler system (open system). For this system, the HFK value for the air supplied to the combustion environment is 1.4. If the temperature and pressure of the air and fuel entering the combustion environment is 25 ° C and 1atm, we calculate the flue gas temperature value of the boiler, assuming that the boiler's thermal efficiency is 60%. All reacting species and reaction products are perfect gases. There is no water condensation in the products. METANAID = 50000 kJ / kg HFK = Air excess coefficient All reacting species and reaction products are excellent gas. Products "no water condensation.
