Se hela listan på neutrium.net The question addressed here is to what extent the Wobbe index, a pivotal standard for gas distribution in the Netherlands, can facilitate the transition towards a more sustainable energy system (that is, a hydrogen economy). The current Dutch energy market heavily relies on gas since a large gas field was found in Groningen. The results showed that a lower methane number and a higher Wobbe index increased and advanced in-cylinder pressure, advanced the combustion phasing, decreased the ignition lag, and shortened the combustion duration, regardless of the operating condition as a result of the higher laminar flame speed and energy density. The Wobbe Index is sometimes called the Interchangeability Factor.¹ Symbol, WN or WI.² .

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). Model No. COSA 9610. Wobbe Index Calorimeter / BTU. Residual Oxygen. Energy. Petrochemical.

Since the Wobbe index relates heating characteristics of blended fuel gases it can be used to obtain constant heat flows from gases of varying compositions. 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. Wobbe Indeks (I W) bruges til at sammenligne brændværdierne mellem forskellige brændbare gasser, såsom naturgas, biogas og bygas.Hvis er øvre brændværdi, også kaldet den kalorimetriske brændværdi, og er specifikke tyngde, så er Wobbe Indekset, , defineret som The formula for calculating Wobbe indix is quite simple.

O índice de Wobbe é utilizado para determinar as características técnicas dos equipamentos e a sua regulação face ao gás que os alimentará (gás natural, gás de petróleo liquefeito (GPL) ou gás de cidade) razão pela qual aparece em geral definido nas especificações dos fornecedores de gases combustíveis e nas características dos equipamentos que os utilizam. The amount of methane in natural gas can greatly affect its Wobbe Index. Most natural gas contains about 90 percent to 95 percent methane by volume after processing.

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. Inherent safety concerns about the risk of explosion, fire management, and environmental impact.

Wobbe index - Wobbe index Från Wikipedia, den fria encyklopedin Den Wobbetalet (WI) eller Wobbe-talet är en indikator på utbytbarhet av bränslegaser såsom naturgas , gasol (LPG), och stadsgas och ofta definieras i specifikationerna för gasförsörjning och transport verktyg.

The measurement of the Wobbe index, a property closely related to calorific value, is discussed briefly in an informative annex, but is not considered in detail in the normative parts of this International Standard. 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.

Wobbe index is an indicator of the interchangeability of fuel gases. The fuel gases include natural gas, liquefied petroleum gas (LPG) and town gas. On the other hand, this value measures the relative ability of fuel gases to deliver energy. Due to the stringent Wobbe Index specification, weathering of LNG must be monitored in the regasification terminal. The heating value and Wobbe Index will gradually increase due to boil-off of the nitrogen components during transit and storage. For the marginal Wobbe Index LNG, the weathering effect may result in off-specification natural gas I2P 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.
