A process of repairing a refractory body, including the steps of a. introducing combustible particles into a first gas stream containing no more than 18% oxygen by volume; b. causing an oxygen-rich gas stream to flow through a particle entrainment zone into a reaction zone adjacent a refractory body to be repaired so as to produce an aspirating effect within the particle entrainment zone effective to induce a flow of the first gas stream containing the combustible particles into the particle entrainment zone and through to the reaction zone; and c. projecting the combustible particles entrained in the oxygen-rich gas stream against the refractory body to cause oxidation of the combustible particles in the reaction zone adjacent the refractory body and generate sufficient heat for one of dressing the refractory body or forming a refractory weld mass thereon.
