Webatoms. Consequently, hydrogen is the lightest gas, about 8 times lighter than methane (representing natural gas). The gravimetric higher heating value "HHV" [4] of a fuel gas are of little relevance for practical applications. In general, the volume available for fuel tanks is limited, not only in automotive applications. Also,

WebThe higher heating value (HHV;also known as the gross calorific value or gross energy) of a fuel is defined as the amount of heat released by a specified quantity (initially at 25 °C) … WebWobbe Number is directly related to the heating value of the fuel. The richer the gas the higher the Wobbe Number and the lower the Methane Number. Contrarily, increasing the Methane Number will decrease the heating value of the fuel. Since pipeline quality gas and natural gas motor fuel are destined for different uses there

Web1 de mai. de 2005 · The reason is that the ash does not make a contribution to the heat release of the biomass combustion. Actually, the HHV in our database varies in the range of about 14.0–22.5 MJ/kg. Converted to the HHV on dry ash free basis, the range is only a bit narrowed to 16.0–23.0 MJ/kg, still a wide variation.
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.
