Abstract

The invention provides a nozzle-mixed burner for use in an endothermic process such as hydrogen reforming or ammonia reforming or ethylene cracking or EDC cracking. The burner (20) comprises a fuel duct (24) extending axially through a wall (22) of the furnace. The fuel duct (24) delivers gaseous fuel (G) to an array of nozzles (26) extending laterally to spray the fuel (G) outwardly into an annular chamber (40) defined by a cap (36). Combustion air (A) is delivered to the chamber (40) by way of a primary air duct (30). A convergent-divergent section (32) of the duct (30) and an outwardly divergent section (44) of the chamber (40) together form a radially extending venturi. Combustion of the fuel (G), supplemented by the venturi effect, draws the air (A) through the duct (30) by natural inspiration.
