The Wobbe Index (WI) is the main indicator of the interchangeability of fuel gases such as natural gas LPG and Town Gas and is frequently defined in the specifications of gas supply and transport utilities. If VC is the higher heating value, or calorific value, and GS … The Wobbe Index is an indicator used to compare the energy output of different fuel gases. To be interchangeable gases, the Wobbe Index needs to be the same. By using air to reduce the LPG energy content, simulated natural gas and natural gas both have the same Wobbe Index. For LPG to have the same Wobbe index as CNG, it has to be mixed with air. A 60:40 ratio for LPG:air mixing is common but it depends upon the composition of LPG because LPG itself is a mixture of propane and butane.

Gas flows through a fixed orifice; there are no moving parts or complex operation which means reliability is unparalleled. The temperature differential is measured, not the absolute temperature of the flame. The Wobbe Index is actually the correct representation of the heating value of natural gas arriving, from the gas line, at the orifice where a burner is located.

cations such as the Wobbe Index, can replace NG in its different applications [23]. burner it presents some difficulties in comparison with NG or LPG due to the

Wobbe Index From the measurement of CH 4 and C2+, the upper and lower heating value is calculated according to ISO EN6976-2005. An additional CO 2 measurement allows the determination of mean molar mass and specific density of the sample probe. Wobbe index is calculated from heating value and specific density, according ISO EN 6976-2005.

Wobbe index — The Wobbe Index (WI) is an indicator of the interchangeability of fuel gases such as natural gas, liquified petroleum gas (LPG), and Town Gas and is frequently defined in the specifications of gas supply and transport utilities. In Europe a gas interchangeability index (the Wobbe Index) is also specified. The Wobbe Index is defined as HHV/ √Gas Specific Gravity (relative to Air) and is often more stringent than the heating value specification.
