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 The Precisive® 5-282 is designed specifically for on-line quality monitoring of natural gas products. It provides fast and accurate measurement of Calorific Value, Wobbe Index, Specific Gravity, and Gas Density along with compositional information, including CO2 in a single, compact analyzer.

Background As a continuation of mandate M400 and supported by the conclusions of the 29th Madrid forum, CEN continues working on finding an EU agreement for a Wobbe Index band, including elaborating on the possibility of regional bands. 2 The Wobbe Index The Wobbe Index is a calculated number on the basis of the higher heating value (Higher Calorific Value) divided by the square root of relative density (gas compared to atmospheric air): Measuring Wobbe Index Turbine damage can be the result from high dynamics that result from variations in the Wobbe Index. An Emerson gas chromatograph provides the accurate, reliable data that is required to ensure no damage to the equipment results from operating on low- or mid-range Wobbe gas.

It is not simply the BTU per cubic foot but rather the BTU per cubic foot divided by the square root of the specific gravity. 2007-06-01 · Moreover, while the Wobbe index is generally regarded as a comprehensive indication of combustion properties, when considering the introduction of hydrogen there is at least one other type of appliance malfunction that can occur that is not solely governed by the Wobbe index: flashback, which is mainly associated with the presence of high flame speed gases such as hydrogen. The Wobbe index is commonly expressed in Btu per standard cubic foot or megajoules per standard cubic meter (1000 BTU/scf = 37.3 MJ/m 3). In the case of natural gas (molar mass 17 g/mol), the typical heating value is around 1,050 Btu per cubic foot and the specific gravity is approximately 0.59, giving a typical Wobbe index of 1,367. 2017-06-09 · Wobbe index (WI) of a gas (normally natural gas) is the indication of the heating value of the gas from the pipeline at the orifice where a burner is located, this could be a gas turbine or a boiler. Wobbe Index / Calorific Value / CARI The COSA 9610™ is the one of the latest instruments from COSA Xentaur for measuring Wobbe Index, BTU/Heating Value and CARI (Combustion Air Requirement Index).

Pure H 2 has a Wobbe index of about 1220 Btu/SCF, whereas natural gas ranges from 1235 to 1396 Btu/SCF. Low Wobbe indexes in fuel gases affect combustion efficiency on devices that have been designed to burn natural gas.

Poor quality fuel sources are often high in nitrogen. Blending with high quality fuel to achieve required heating value is preferred over costly scrubbing to remove […] 2007-07-30 The corresponding range for the Wobbe index is usually between 40 MJ/m 3 and 60 MJ/m 3.
