Higher heating value of hydrogen

Web5 de mar. de 2024 · 3. When advanced combustion units having secondary or tertiary condensers are designed, the appropriate fuel value to use in the design process is the … The difference between the two heating values depends on the chemical composition of the fuel. In the case of pure carbon or carbon monoxide, the two heating values are almost identical, the difference being the sensible heat content of carbon dioxide between 150 °C and 25 °C (sensible heat exchange causes a change of temperature, while latent heat is added or subtracted for phase transitions at constant temperature. Examples: heat of vaporization or heat of fusion). For hydrog…
