The Wobbe Index is a measure of the interchangeability of fuel gases and their relative ability to deliver energy. It gives an indication of whether a turbine or burner will be able to run on an alternative fuel source without tuning or physical modifications. The formula for calculating Wobbe indix is quite simple. Its the gross heating value (in MJ/Sm3) divided by the square root of the specific density of the gas at standard conditions (15 deg C and 1 atm abs). 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.

dansk naturgas. Priserne ligger for brændværdi-/wobbemålerne i området 140.000 – 410.000 DKK, hvor de højeste priser også omfatter et fuldt udrustet, opvarmet kabi- Wobbe index is a measure of the quality of fuel such as ignition and combustion properties in spark-ignition engines– it is a critical gas quality parameter for gaseous-fueled engines. IS 14504: Natural Gas - Calculation of calorific values, density, relative density and Wobbe Index from composition Item Preview remove-circle Share or Embed This Item. The fast and reliable analysis of the natural gas composition requires the simultaneous quantification of numerous gaseous components. To this end, fiber-enhanced Raman spectroscopy is a powerful tool to detect most components in a single measurement using a single laser source. NATURAL GAS CALORIFIC VALUE/WOBBE INDEX MONITOR the Precisive® 5-282 is designed specifically for on-line quality monitoring of natural gas products.

Naturgas - Beräkning av värmevärde, densitet, relativ - SIS

Le mesurage de l'indice de Wobbe, une propriété étroitement liée au pouvoir for Heating Value of Gases in Natural Gas Range by Stoichiometric Combustion. L'indice de Wobbe est le quotient, sur une base volumique, du pouvoir calorifique d'un gaz par la racine carrée de sa densité relative par rapport à l'air. 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 proposed to help gain insight into the relationship between the Wobbe Index (WI) and engine power, and it provides a practical method for estimating the engine Combustible Gas Analyser · What Is The Wobbe Index? · The Wobbe Index is actually the correct representation of the heating value of natural gas arriving, from the For most gas users, adjustment for the typical combustion characterising quantities such as the Wobbe Index, the calorific value and the. Methane Number is The measurement of gas composition is used to analyse and calculate calorific values, Wobbe index and other quality parameters of the natural gas. Calculating 15 Apr 2019 A larger use of natural gas in internal combustion engines will reduce the dependence upon petroleum imports. However, large variations in current and potential future rates of change of Wobbe Index in distribution networks.
