    摘要: A fuel stream comprising a combustible pulverized material entrained in a carrier gas is formed and subsequently injected into a blast furnace with the hot blast air without any detrimental effect on the hot air blast and with minimum energy consumption. The volume flow rate and pressure of the carrier gas are controlled as functions of the furnace pressure and the pulverized material feed rate is simultaneously controlled as a function of the carrier gas pressure drop.

    摘要: A pulverized fuel delivery system for a blast furnace in which pulverized coal is delivered in dense phase fluidized form into the blast furnace from gas pressurized tanks that are placed in communication, one at a time, in cyclical sequence with a pneumatic transport means. The tank gas pressure is regulated in accordance with the blast furnace wind rate to control the weight flow rate of pulverized coal into the furnace and the transport gas flow rate is regulated in accordance with the fuel weight flow rate to maintain a prescribed transport gas flow rate per pound of coal delivered to the furnace.
