The Wobbe Index indicates the interchange ability of a fuel gas and is the best indicator of similarity between natural gas and a specific propane-air mixture. Since the Wobbe index relates heating characteristics of blended fuel gases it can be used to obtain constant heat flows from gases of varying compositions. For the purposes of the Wobbe index, fuel gasses are split up into three families, which are the manufactured or "town" gas, natural gas, and liquefied petroleum gas (LPG).

It LPG-Air Mixers. LPG-Air (SNG) mixers blend vaporized LPG with air to achieve a mixture suitable for use in natural gas appliances. When used for natural gas replacement, LPG-air mixers must blend the gases at a rate equal to the appliance rate of consumption, and at a quality such that end-use equipment performs equally well under either gas. Several methods exist to achieve LPG + Air blending.

Pressure, specific gravity, and calorific value make up a fuel's potential energy, and vary between families and even among gases of the same type, depending on the supplier. –WI is Wobbe number or Wobbe Index, an indication of interchangeability of fuel gas.

In the case of natural gas ( molar mass 17 g/mol), the typical heating value is around 1,050 BTU per cubic foot and the specific gravity is approximately 0.59, giving a 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.

Wobbetalet in English with contextual examples - MyMemory

The Wobbe number is named for the Italian engineer Goffredo Wobbe, who in 1926 published a paper³ defining a measure of fuel gas “quality”, with the idea that fuels of the same quality would be interchangeable. Only gases that have the same Wobbe index are interchangeable.
