A method for evaluating the Wobbe index of a fuel gas belonging to a family of gases. The method includes measuring mass flow rates the fuel gas and of a reference gas, which is not necessarily a fuel gas at respective absolute pressures and temperatures and in a sonic flow through a microjet. An evaluation of the Wobbe index (W) of the fuel gas as W=A&#xd7;Y+B uses the results of measurements of the fuel gas and the reference gas and is established for all the gases of the family considered.

Method and device for evaluating a fuel gas wobbe index

A method of regulating the calorific power of a stream of gaseous fuel of the fossil-gas type, comprising a predominant fuel gas, denoted &ldquo;A&rdquo; and flowing in a pipe. This regulation is performed, at least partly, by controlled addition of at least one fuel gas called having a calorific power greater than that of &ldquo;A&rdquo; into the stream. The subject of the invention is also its apparatus for implementation and its applications.
