Wobbe index is similar to these topics: Gas meter, Liquefied petroleum gas, LPG carrier and more.

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

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. Wobbe Index value by adding air to natural gas and varying the air and gas mixture flow rate; gross calorific value control by adding air or LPG to natural gas. All the tested settings gave good results. This report illustrates these results and the main features of the control system.

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 . 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. The GA500™ burns a sample of the LPG/Air mixture to provide an accurate measurement of the Wobbe Index.

ประกาศกรมธุรกิจพลังงาน เรื่อง กำหนดลักษณะและคุณภาพของก๊าซธรรมชาติสำหรับยานยนต์ พ.ศ. ๒๕๕๒ Wobbe index — The Wobbe Index (WI) is an indicator of the interchangeability of fuel gases such as natural gas, liquified petroleum gas (LPG), and Town Gas and is frequently defined in the specifications of gas supply and transport utilities.

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.

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.

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

Pressure, specific gravity, and calorific value make up a fuel's potential energy, and vary between families and even among gases of the same type, depending on the supplier.

The New COSA 9610™ is the latest instrument from COSA Xentaur for measuring Wobbe Index, BTU/Heating Value and CARI (Combustion Air Requirement

By using air to reduce the LPG energy content, simulated natural gas and natural gas both have the same Wobbe Index. Not to sound like a grinch, but the wobbe Index is just a measure of how much heat you get through a hole at constant (and low) pressure. The volume flow through an orifice is basically related to the formula for velocity pressure in the hole and the heat release of the eventual flame is the calorific value x the volumetric flow.
