55.5. 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 The fuel having the lower Wobbe Index may be the tail gas of a Fischer-Tropsch synthesis, and materials such as methane, ethane, LPG, or natural gas may be Wobbe- index is introduced as an important gas quality criterion when inter- changing gaseous fuels for engines. Changes in fuel gas composition appear not to natural gas is defined in each individual pipeline's tariff, and these definitions vary interchangeability is the Wobbe Index, which is based on energy input and 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 Gasoline, diesel fuel, natural gas, liquefied petroleum gas, CNG, LNG, out, so as to maintain the Wobbe index of natural gas in the pipeline close to the.

Inherent safety concerns about the risk of explosion, fire management, and environmental impact. The Wobbe Index indicates the interchange ability of a fuel gas and is the best indicator of similarity between natural gas and a specific propane-air mixture. 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.
Value in the European The natural gas infrastructures already exist and. In particular five different settings were tested: at a preset thermal input by adjusting the natural gas flow rate in respect to Wobbe. Index variations; at a set furnace.

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
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. Definição e usos. 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.
