The Wobbe index (WI) or Wobbe number [1] 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.

What Is The Wobbe Index? The Wobbe Index is actually the correct representa-tion of the heating value of natural gas arriving, from the gas line, at the orifice where a burner is located. The calorific value, or heating value, of a gas is proportional to its specific gravity.

Wobbe index for fuel gases like propane, butane, methane and more. 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.

Jul 3, 2009 · The Wobbe index is essential for analyzing the impact of a fuel changeover and is also a common specification of appliances that use gas and of devices that transport gas. The Wobbe index may be calculated from the higher heating value (HHV) and the specific gravity of …

The Wobbe Index is a measure of the energy release rate of a gas fuel when it is burned under specific conditions. It is defined as the ratio of the Calorific Value of the gas to the square root of its specific gravity.

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.

Jun 23, 2024 · The Wobbe index of a gas is a measure of the energy that will flow through a given burner orifice. If V C is the higher heating value, or higher calorific value, and G S is the specific gravity, the Wobbe index, I W, is defined as:

The Wobbe Index is a measure of the interchangeability of fuel gases and their relative ability to deliver energy. It gives an indication of whether a turbine or burner will be able to run on an alternative fuel source without tuning or physical modifications.

Aug 30, 2023 · The Wobbe Index, also known as the Wobbe Number or Wobbe Value, is a parameter used to characterize the interchangeability of different fuel gases in terms of their energy content and combustion...

Implementation of the Wobbe Index proposal as part of the CEN standard EN 16726: the WI proposal for entry points is wider than the legal WI limits in some Member States and could lead to A-deviations on a revised EN 16726 standard.
