The burner comprises a water- coolable elongate housing (1) having at one end separate inlets for individual gas flows of oxygen (7), steam (12) and combustible gas (2) and at the other end an outlet for discharge of the combined gas flows and a distributing grid (3) to distribute the combustible gas flow upstream of the said outlet. Oxygen is supplied through pipe (7) to a receiver (8) provided with a first grid (9) in which an arrangement of pipes (10) is secured. Steam is supplied through an annular conduit defined between pipe (11) and pipe (7), which pipe (11) extends to a receiver (13) provided with a second grid (14) with an arrangement of pipes (15) secured therein. Combustible gas is supplied through an annular conduit defined between an outer pipe (1) surrounding the pipe (11) and pipe (11) itself, which pipe (1) leads to a third grid. The burner is employable in chemical industry, e.g. for the cleavage of natural gas with oxygen gas and steam, and is reliable in operation within a wide combustible gas, oxygen and steam loading range.
