5. As scheduled, blast furnace No. 6 followed approximately 1 month later. Initially operated at natural gas injection rates of 90 kg/tHM, both blast furnaces are now operated at combined natural gas and pulverized coal injection rates above 180 kg/tHM. The ramp-up to nominal injection rates was achieved in less than 3 months after PCI start-up.
PURPOSE: To provide an operation method for improving thermal energy storage effect and furnace efficiency, consuming excess blast furnace gas more in gases generated from an ironworks and reducing coke oven gas by constantly maintaining temperature of combustion gas and air supplied to hot stove to constantly maintain flame temperature.
