Fuel oil injector for blast furnaces - avoids formation of carbon black inside the furnace

Abstract

Abstract Blast furnace fuel oil injector has (a) hot blast supply with a blast pipe, supply tube, tymp, and a tuyere, and (b) a high calorific energy spray burner with shock wave flame stabilisation and comprising a straight pipe supplying a combustive gas with a divergent outlet (I) an injector (II) whose cross section is greatest at (I) so that the space between the pipe wall and (IIe forms an annular supersonic convergent-divergent nozzle whose minimum cross-section ensures that the speed of sound is attained at minimum burner flowr rate. (II) has means for supplying fuel oil into the divergent part of the nozzle and for adjusting the posn. of (II) in the nozzle.
