ABSTRACT:
An exothermic reactor has a refractory lining and a plurality of annular nozzles mounted in said lining. Each nozzle has an inner reactant gas passage and an annular shielding fluid passage surrounding said reactant gas passage. A reactant gas is supplied from a reactant gas manifold through reactant gas feed conduits to respective ones of said reactant gas passages. A shielding fluid is supplied from a shielding fluid manifold through shielding fluid feed conduits to respective ones of said shielding fluid passages. The pressure in said reactant gas manifold is sensed and the flow in each of said shielding fluid feed conduits is controlled in dependence on the conditions in said reactant gas manifold so as to prevent a pressure rise in each of said shielding fluid feed conduits above an upper limit. As long as said pressure is below said upper limit, a predetermined ratio is maintained between the flow rate in each of said shielding fluid feed conduits and the flow rate in said reactant fluid manifold.
