Abstract
An apparatus for forming a refractory mass on a surface of a substrate by spraying against the surface a mixture of particles including oxidizable particles and refractory particles in a carrier gas, which carrier gas may contain oxygen but is not substantially all oxygen, and combusting the oxidizable particles to generate sufficient heat to soften or melt at least the surfaces of the refractory particles and form the refractory mass, which apparatus includes means for mixing the mixture of particles with a stream of the carrier gas; a lance having an outlet; a feed line for conveying the carrier gas and entrained mixture of particles to the lance outlet for spraying and having defined therein at least one orifice located downstream of the mixing means and at least 1 m from the lance outlet; and means for introducing oxygen gas into the carrier gas and entrained mixture of particles connected to the at least one orifice defined in the feed line.
