<p>Means are provided for collecting gas containing combustible constituents and for adding oxidizing gas to the gas containing combustible constituents to determine the content of combustible constituents in this gas by burning the combustible constituents with the oxidizing gas. A first chamber is made connectible to the gas containing combustible constituents and is partially limited by a first movable wall the movability of which enabling the first chamber to be filled and emptied of gas. containing combustible constituents. A second chamber is connectible to the oxidizing gas and is partially limited by a second movable wall, the movability of which enabling the second chamber to be filled and emptied of oxidizing gas. The second movable wall is movable together with the first movable wall at a constant distance from the first movable wall and the first chamber and the second chamber are connectible to a space outside the chambers to bring together the gases collected to the chambers.</p> |
