A method is provided for estimating at least one combustion characteristic of a fuel gas belonging to a family of fuel gases, where the at least one characteristic includes at least one of a Wobbe index or a higher heating value. The method includes measuring at least two flow properties of the fuel gas and measuring a dihydrogen content Xcontained in the fuel gas. The method also includes estimating the at least one characteristic using an empirical affine relationship of Here, &#x3b1;, &#x3b2;, and &#x3b3; are coefficients predetermined for the family of fuel gases, and Y is a variable representative of physical properties of the fuel gas prepared from the measurements of the at least two flow properties of the fuel gas.

A device for stabilizing dilute combustion for use in a cold-walls type combustion chamber comprises a burner. The burner comprises at least one oxidant inlet and at least one fuel inlet. The oxidant and fuel inlets opening separately into the chamber at a distance suitable for establishing combustion which is highly diluted by internal re-circulations of combustion products toward a burner zone. The device comprises a heating element configured to heat, during steady operating conditions, the combustion products to sustain self-ignition conditions. The heating element is positioned in a dilution zone and surrounds a set of oxidant and fuel jets.
