Abstract
An improved combustion head for use with flame spray apparatus constructed according to the principles described in U.S. Pat. No. 4,416,421 is provided with a recess in the floor of the counterbore receiving hot pressurized combustion gases from the combustion chamber. The recess is of depth sufficient to redistribute the heat of the combustion gases to prevent local hot spots in the counterbore and to avoid cracking and erosion in the combustion head by reducing thermal fatigue which occurs in cyclic use of the flame spray apparatus. The improved combustion head is also provided with radially spaced longitudinal channels extending inwardly from the periphery thereof, along which channels cooling water is passed to cool the improved combustion head.
