2017-10-01 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. British Standard 7859 provides all the details on standard conditions, component heating values, ideal vs. non-ideal Wobbe Index is used to compare the combustion energy output of different composition fuel gases. Two fuels with identical Wobbe Index at given pressure and valve setting (orifice size) the energy output will be identical. The variation in WI is typically upto 5% (but maximum could be 10% for some manufacturer). 2000-07-01 The Wobbe Index (WI) or Wobbe number is an indicator of the interchangeability of fuel gases such as natural gas, liquefied petroleum gas (LPG), and town gas and is frequently defined in the specifications of gas supply and transport utilities.

It is a mixture of propane and butane. The calorific value of domestic LPG is about 116 MJ/m3 and its flammable limits are approximately 1.8 ～ 9.5%. The Wobbe Index of LPG is 84. LPG is colourless, odourless, non-toxic, flammab le, … the Wobbe Index, Combustion Air Requirement, Calorific value based on a residual oxygen measurement.

On the other hand, this value measures the relative ability of fuel gases to deliver energy. The Wobbe Index of LPG is 84. LPG is colourless, odourless, non-toxic, flammable, explosive and heavier than air. As it is approximately 1.91 times the weight of air, it tends to accumulate on the ground level. The Wobbe Index in the H-gas standard and renewable gases in gas quality standardisation Presentation by CEN Sector Forum Gas WG Pre-normative studies on H-gas quality parameter (SFGas GQS) Kris de Wit, Chair (kris.dewit@gasbe.de) Madrid Forum 14+15-10-2020 Gases having the same Wobbe index are held to be interchangeable. LPG-based SNG is used in emergency backup systems for many public, industrial and military installations, and many utilities use LPG peak shaving plants in times of high demand to make up shortages in natural gas supplied to their distributions systems. LPG-SNG installations are also used during initial gas system introductions when the distribution infrastructure is in place before gas supplies can be connected.
