Предложен способ для комбинированного ввода пылевидного угля и газообразного окислителя в металлоприемник шахтной печи, в частности доменной печи, через фурму для дутья горячего воздуха. В зоне конца сопла фурмы в металлоприемнике пылевидный уголь вводят в дутье горячего воздуха в форме полой кольцеобразной струи, а газообразный окислитель вводят внутрь полой кольцеобразной струи. Копье для осуществления способа содержит две коаксиальные трубы и распределительное устройство, снабженное центральным отверстием для пылевидного угля.A method is proposed for the combined introduction of pulverized coal and a gaseous oxidizer into a metal receiver of a shaft furnace, in particular a blast furnace, through a lance for blowing hot air. In the zone of the end of the tuyere nozzle in the metal receiver, pulverized coal is introduced into the blast of hot air in the form of a hollow annular jet, and a gaseous oxidizer is introduced into the hollow annular jet. The spear for carrying out the method comprises two coaxial pipes and a switchgear provided with a central hole for pulverized coal.
