ABSTRACT:
Apparatus for repairing a refractory body, such as a furnace wall by projecting combustible particles in an oxygen-rich carrier gas against such body to cause oxidation of combustible particles in a reaction zone adjacent such body and thereby the generation of heat required for dressing such body or forming a refractory weld mass thereon, wherein the combustible particles are introduced into a first gas and oxygen-rich gas is forced through an entrainment zone 6 in which it produces an aspirating effect whereby a flow of combustible particles and first gas is induced into the entrainment zone 6 and the induced flow of combustible particles and first gas is carried along a conduit 9 and a lance 21 with the oxygen-rich gas to the reaction zone.
