摘要： The invention relates a floating entrainment metallurgical process. In this process, the reaction gas and the powdery materials are injected into the reaction furnace, aiming to obtain a controllable highly rotating and floating state and reach the ignition point under the high-temperature radiation of the reaction furnace to combust intensely. Meanwhile, the rotating fluid injected in the reaction furnace will drive the furnace gas, and forms a relatively low-temperature circular backflow protection area around the rotating fluid. The reaction gas is tangentially fed into the rotating generator along numbers of rotary channels to form a controllable rotating airflow, in addition, a conical exit air controller that can be moved up and down is adopted to control the exit area of the rotating generator, thus controlling the velocity of the reaction gas into the reaction furnace; the powdery materials fall freely around the reaction gas and are involved in the high-speed rotating airflow, forming a rotating fluid, of which the powdery materials are highly dispersed into the reaction gas, moving downwards along the radial high-speed rotating axle. For the purpose of this invention, a steplessly adjusted reactor is as well referred to in this invention.
