Abstract

A method and an arrangement for operating a supersonic tuyere having a convergent and a divergent passage portion separated by a neck in such a manner so as to produce in the divergent passage portion a shock wave to atomize a combustible material fed in the region of the neck into the tuyere. The shock wave is produced by more or less restricting the open cross section of the neck, preferably by adjusting the axial position of a solid body in the convergent portion of the tuyere with respect to the neck, to maintain the pressure of a combustion sustaining material fed into the tuyere upstream of the convergene portion, during variation of the fed amount of such material within predetermined limits, at such a magnitude to assure production of a shock wave at the divergent portion.
