Device for producing a hydrogen - gaseous hydrocarbon mixture

A device for producing a mixture of gaseous hydrocarbon and hydrogen arranged to be disposed upstream of at least one gas burner, comprising:

• at least:
• a Venturi tube,
• a first inlet opening disposed at the inlet of said venturi tube and arranged to be connected to a supply pipe,
• an outlet opening disposed at the outlet of said Venturi tube and arranged to be connected to a pipe for discharge of the mixture of gaseous hydrocarbon and hydrogen produced by said device,
• a second inlet opening arranged to be connected to a hydrogen supply pipe,
• a hydrogen safety and regulation unit connected by its inlet to said second inlet opening and by its outlet at the neck of said Venturi tube and making it possible to regulate the hydrogen pressure at the neck of said Venturi tube proportionally to the gaseous hydrocarbon supply pressure at the first inlet opening, and
• a differential pressure switch detecting a pressure difference between the inlet and the neck of said Venturi tube,
• a pressure switch measuring the pressure of hydrogen entering said device through its second inlet opening, and
• an electronic control box for regulating the hydrogen supply of the device using said hydrogen safety and regulation unit according to the pressure measurements of the pressure switch and the differential pressure switch according to a manual mode or according to an automatic mode.
