Abstract The variations of chemical exergy with ambient temperature from −30 °C to 45 °C, pressure from 0.6 to 1.1 bar and relative humidity (RH) from 10% to 100% were investigated for gaseous fuels and atmospheric gases on the basis of Szargut’s model. It was found that the variations are significant. At ambient pressure of 1 atm and RH at 70%, the chemical exergy of hydrogen increased 0.7–0.8% per 10 °C of lower ambient temperature, while for methane, the increase was 0.25–0.30%. For other… CONTINUE READING
