Title (EN) METHOD FOR ESTIMATING A COMBUSTION CHARACTERISTIC OF A GAS THAT MAY CONTAIN DIHYDROGEN
(FR) PROCEDE D'ESTIMATION D'UNE CARACTERISTIQUE DE COMBUSTION D'UN GAZ POUVANT CONTENIR DU DIHYDROGENE
Abstract:
(EN) Method for estimating at least one combustion characteristic of a combustible gas belonging to a family of combustible gases, said at least one characteristic being the Wobbe index or the higher calorific value, the method comprising: measurement (E01) of at least two flow properties of said combustible gas, measurement (E02) of the dihydrogen content XH2 of said combustible gas, said at least one characteristic ΞGN/H2 being estimated (E03) by means of the following refined empirical law: ΞGΝ/Η2 = α + β x Y + γ x XH2 where α, β, and x are predetermined coefficients for the family of combustible gases, and Y is a variable indicative of physical properties of said combustible gas, formulated on the basis of said measured values of said at least two flow properties of said combustible gas.
(FR) Procédé d'estimation d'au moins une caractéristique de combustion d'un gaz combustible appartenant à une famille de gaz combustibles, ladite au moins une caractéristique étant l'indice de Wobbe ou le pouvoir calorifique supérieur, le procédé comprenant : une mesure (E01) d'au moins deux propriétés d'écoulement dudit gaz combustible, une mesure (E02) du taux XH2 dihydrogène contenu dans ledit gaz combustible, ladite au moins une caractéristique ΞGN/H2 étant estimée (E03) au moyen de la loi affine empirique suivante : ΞGΝ/Η2 = α + β ⋅ Y + γ ⋅ XH2 avec α, β, et y des coefficients prédéterminés pour la famille de gaz combustibles, et Y une variable représentative de propriétés physiques dudit gaz combustible élaborée à partir desdites valeurs mesurées desdites au moins deux propriétés d'écoulement dudit gaz combustible.
