Hydrogen gas burner

A hydrogen gas burner comprising:

• a first, axially extending, tubular pipe having an axial slot in a sidewall thereof;
• an axially elongate duct having an axially elongate upper ledge protruding radially outwardly from an upper periphery of the axial slot, an axially elongate lower ledge protruding radially outwardly from a lower periphery of the axial slot, and an axially elongate plate affixed to respective radially outward, terminal ends of the upper ledge and the lower ledge, the axially elongate duct being in fluid communication with an interior of the first pipe and the axially elongate plate having a plurality of through-holes formed therethrough, the through-holes fluidly communicating the interior of the first pipe with an exterior thereof;
• a second, axially extending, tubular pipe, having an axial opening in a sidewall thereof, the axial opening spanning at least a portion of an axial extent of the second pipe, the first pipe being substantially nested within the second pipe and the axially elongate duct projecting radially outwardly through the axial opening, the axial opening including a substantially linear base edge surface in substantially continuous contact with the lower ledge of the axially elongate duct;
• a combination gas valve and pressure regulator connected to an inlet of the first pipe, the combination gas valve and pressure regulator being configured to fluidly connect a source of hydrogen gas with the interior of the first pipe, such that the hydrogen gas flows into the first pipe via the inlet thereof;
• and
• an igniter configured to provide an electrical spark adjacent at least one of the plurality of through-holes, and, in turn, ignite and initiate combustion of the hydrogen gas exiting from the first pipe and the axially elongate duct via the plurality of through-holes.
