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.

Wobbe index is an indicator of the interchangeability of fuel gases such as natural gas, liquefied petroleum gas. (LPG), and town gas, It is frequently defined in 

LPG heating value control involves   The heating value (HV) of natural gas is strongly tied to the Wobbe index Pure methane has a specific gravity of 0.554 while for ethane and propane the  5 Nov 2020 For example, can propane be used in a kitchen range made to burn natural gas? The Wobbe Index is sometimes called the Interchangeability  3 days ago 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  H = calorific value =1017 BTU/SCF. 0 = original gas m = SNG mix consisting of LPG and air.

Following Scotland's trial where gas appliances have been run on a less pure form of natural gas, Martyn Bridges, Director of Marketing and Technical Support Wobbe index: | The |Wobbe Index| (WI) or |Wobbe number||[1]| is an indicator of the interchangeabil World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. 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. 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.

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. By using air to reduce the LPG energy content, simulated natural gas and natural gas both have the same Wobbe Index.

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.

2017-10-01 · Wobbe index is an indicator of the interchangeability of fuel gases such as natural gas, liquefied petroleum gas (LPG), and town gas, It is frequently defined in the specifications of gas supply and transport utilities. The Wobbe Index is used to compare the combustion energy output of different composition of fuel gases in appliance.

Only gases that have the same Wobbe index are interchangeable. 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. Therefore, the most common applications for LHV Wobbe Index systems are: (Petro) Chemical plants Blast-furnace and cokery plants Cogeneration power plants Fuel gas control for burners and ovens Gas bottles production Gas turbines & gas engines Glass and porcelain factories (furnaces & ovens control) The GA500™ burns a sample of the LPG/Air mixture to provide an accurate measurement of the Wobbe Index.

BG-LPG mixed fuels were defined so as to have a Wobbe index (WI) nearly equivalent to those of natural gas (NG). The qualities of BG and LPG used are
