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.

All the tested settings gave good results. This report illustrates these results and the main features of the control system. –WI is Wobbe number or Wobbe Index, an indication of interchangeability of fuel gas. – Gaseous fuel having the same WI can be interchanged with no significant physical changes to the burner..(8) SG WI kd û3 WI kd û3 WI..(7)..(6) SG CV kd û3 SG CV kd û3 LPG 2 0.5 NG LPG 2 0.5 NG LPG 2 0.5 LPG CAM designs, manufactures, and installs SNG plants, LPG air mixing plants, in addition, stand by, or alternative to natural gas. We also mix low heating value gas, industrial process gas, with LPG or natural gas for energy saving purposes The Wobbe Index is sometimes called the Interchangeability Factor.¹ Symbol, WN or WI.² .
This European Standard does not cover LPG containers for liquefied The Wobbe index is said to be gross or net according to whether the calorific value used
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.
Wobbe - Index: 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. The Wobbe - Index was defined 1927 by the engineer Goffredo Wobbe. It
LPG/air mixing ratios average 60/40, though this is widely variable based on the gases making up the LPG. The method for determining the mixing ratios is by calculating the Wobbe index of the mix. Gases having the same Wobbe index are held to be interchangeable.

If VC is the higher heating value, or calorific value, and GS … 2013-09-13 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. This mixture of LPG and air to substitute natural gas … 2006-01-11 CAM designs, manufactures, and installs SNG plants, LPG air mixing plants, in addition, stand by, or alternative to natural gas.
