Vorrichtung zur Feststellen vom Wobbe-Index einer Gasmischung

摘要

Device for determining the Wobbe index of a first gas mixture, comprising a mixing chamber, means for supplying the first gas mixture to the mixing chamber via a first number of openings, means for supplying an oxidation gas to the mixing chamber via a second number of openings, means for keeping a constant ratio between the quantity of first gas mixture and the quantity of oxidation gas supplied to the mixing chamber, means for burning the second gas mixture formed in the mixing chamber and means for determining the oxygen content of the combustion gas obtained after combustion, in which the ratio of the diameters of the openings for the supply of the first gas mixture and the oxidation gas to the mixing chamber is chosen such that the Reynolds numbers of the flows of first gas mixture and oxidation gas through the openings are equal, and that the number of openings is determined by the desired ratio of the flow rates of first gas mixture and oxidation gas.
