Abstract
Combustion assembly with a non-metallic refractory block (10) of height (h) between lower (11) and upper (12) ends, having opposite inlet and outlet faces (13), distributed over its height (h) in stages (et1, et2, et3, et4) each comprising a passage for fuel and / or oxidizer injection extending between the faces and terminating in an injection opening (21, 22, 23) in the outlet face (13), each opening (21, 22, 23) defining a contact rectangle (25) with two segments perpendicular and two parallel to the height (h), a burner per stage generating flames of variable length at constant flame power, each with fuel injectors (31) and oxidizer injectors (32, 33) respectively connected to fuel and oxidizer inlets, the injectors being inserted in the passages so that the inlets are on the inlet face,The passages being oriented and spaced so that the flames generated downstream of the outlet face (13) are spaced apart and non-convergent, the contact rectangle (25) at the lower end (11) having segments perpendicular to the height (h) at least twice as long as the segments parallel to the height (h). Furnace comprising the combustion assembly. Figure from the abstract: Figure 1,
