Swedish Standards corresponding to documents re-ferred to in this Standard are listed in ”Catalogue of Swedish Standards”, annually issued by SIS. The Catalogue lists, with reference number and year of 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 is the specific gravity, the Wobbe Index, IW, is defined as. Se hela listan på neutrium.net 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 the main indicator of the interchangeability of fuel gases and is frequently defined in the specifications of gas supply and transport utilities.

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. 2007-07-30 · States typically has a Wobbe number between 1310 and 1390.” Equipment is rated to operate over a specified Wob-be Index range and, in some cases, provides an adjustment that corresponds to the Wobbe Index.

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. Upper Wobbe Index (kcal/Nm 3) Lower Wobbe Index (kcal/Nm 3) Hydrogen: 11,528: 9,714: Methane: Wobbe Index for LPG. The Wobbe Index is used to compare the energy output of fuel gases in heating applications. It is often used as an indicator of the interchangeability of fuel gases, including LPG and natural gas. Wobbe Index is measured in megajoules per cubic metre of gas – MJ/m3. 2018-09-15 · Wobbe index is an indicator of the interchangeability of fuel gases. The fuel gases include natural gas, liquefied petroleum gas (LPG) and town gas.

The Wobbe Index is sometimes called the Interchangeability Factor.¹ Symbol, WN or WI.² . 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.
