Abstract: A device for blowing a reactive liquid into a melt which includes an atomization nozzle and a plurality of parallel bores having such a ratio of length to diameter as to cause emission of the reactive liquid as a corresponding plurality of parallel streams of atomized liquid.

Abstract: Liquid droplets in a freely falling stream are applied as a liquid reaction agent in the generation of a spatially-limited convective reaction system in such a way as that at least a portion of the droplets penetrate into the surface of the molten bath to interact with the molten metal.

Abstract: A device for obtaining large amounts of combustible gas from carbonaceous materials, such as wood chunks and other wood waste material, by gasification of such wood material resulting in partial combustion thereof has a gas-tight combustion chamber having a rectangular cross section and having a material charging device and an ash discharge device respectively disposed at upper and lower portions thereof. The chamber has a number of gas removal lines connected thereto and has a number of air nozzles uniformly disposed in longitudinal walls of the chamber in at least one plane as well as a number of uniformly spaced air supply lances which extend to a central interior portion of the chamber for supplying air for aiding combustion of the material therein. The device may be subdivided into a number of individual chambers by partitions disposed in the chamber.
