Abstract

Patente de Invenção: FORNO DE CUBA E MÉTODO PARA OPERAR O MESMO. A presente invenção refere-se a um forno de cuba, especificamente um forno de cúpula, para fundir uma matéria-prima que contém metal, que está provido com pelo menos um dispositivo de bocal. O dispositivo de bocal compreende um bocal de saída para emitir um sopro residual, a extremidade a jusante do qual está conectada a uma linha de sopro residual, e um local de jato para suprir um meio bombeado que contém oxigênio, a extremidade a jusante do qual está conectada a uma linha de meio bombeado. Uma linha de sopro de injetor que está conectada na linha de meio bombeado. Uma linha de sopro de injetor que está conectada na linha de meio bombeado ou no local de jato está também provida. Uma extremidade de saída do bocal de jato está equipada com uma lança de injetor e a lança de injetor está diposta dentro do bocal de saída de tal modo que o bocal de saída circunde a lança de injetor concentricamente. O bocal de jato está projetado de tal modo que o meio bombeado é acelerado dentro do bocal de jato e um sopro de injetor é aspirador devido à acelerado dentro do bocal de jato e um sopro de injetor é aspirado devido à pressão reduzida que prevalece quando o meio bombeado é acelerado e o sopro de injetor é então mesclado com o meio bombeado é acelerado e o sopro de injetor é então mesclado com o meio bombeado para formar um fluxo de bocal de jato, e que o fluxo de bocal de jato e um sopro residual são alimentados para o forno de cuba. De acordo com a invenção, o dispositivo de bocal compreende pelo menos uma lança de combustível a qual é um componente integral do dispositivo de bocal, e a extremidade a jusante da qual está conectada a uma linha de combustível. O dispositivo de bocal está projetada de tal modo que o fluxo de bocal de jato carrega o combustível juntamente com este, de modo que o fluxo de bocal de jato mistura com o sopro residual e o combustível, e o fluxo de bocal de jato que resulta destes é injetado no forno de cuba através do dispositivo de bocal.Invention Patent: CUBA OVEN AND METHOD FOR OPERATING THE SAME. The present invention relates to a bowl oven, specifically a dome oven, for melting a metal-containing raw material which is provided with at least one nozzle device. The nozzle device comprises an outlet nozzle for emitting a residual blow, the downstream end of which is connected to a residual blowing line, and a jet location for supplying a pumped medium containing oxygen, the downstream end of which is connected to a pumped middle line. An injector blow line that is connected to the pumped middle line. An injector blow line that is connected at the pumped medium line or at the jet site is also provided. One outlet end of the jet nozzle is equipped with an injector boom and the injector boom is disposed within the outlet nozzle such that the outlet nozzle surrounds the injector boom concentrically. The jet nozzle is designed such that the pumped medium is accelerated within the jet nozzle and an injector blow is aspirated due to accelerated within the jet nozzle and an injector blow is aspirated due to the reduced pressure prevailing when the nozzle is pumped. pumped medium is accelerated and the nozzle blow is then mixed with the pumped medium is accelerated and the nozzle blow is then mixed with the pumped medium to form a jet nozzle flow, and that the jet nozzle flow and a blow The waste water is fed into the vat oven. According to the invention, the nozzle device comprises at least one fuel lance which is an integral component of the nozzle device, and the downstream end of which it is connected to a fuel line. The nozzle device is designed such that the jet nozzle flow carries the fuel together with it, so that the jet nozzle flow mixes with the residual blow and fuel, and the resulting jet nozzle flow of these is injected into the vat furnace through the nozzle device.
