LPG-Air (SNG) mixers blend vaporized LPG with air to achieve a mixture suitable for use in natural gas appliances. When used for natural gas replacement, LPG-air mixers must blend the gases at a rate equal to the appliance rate of consumption, and at a quality such that end-use equipment performs equally well under either gas. Several methods exist to achieve LPG + Air blending. 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. 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. 2017-10-01 !!!!!SNG,!LPGTAir,!PropaneTAir!!–!The!LPG!Opportunity!!!!! !

The Wobbe Index is used to compare the energy output of fuel gases in heating applications.

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. 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.

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. Only gases that have the same Wobbe index are interchangeable.

Ship Chem EU. The GA500™ burns a sample of the LPG/Air mixture to provide an accurate measurement of the Wobbe Index. Gas flows through a fixed orifice; there are no moving parts or complex operation which means reliability is unparalleled. The temperature differential is measured, not the absolute temperature of the flame.

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.
