Disclosed is a pulverizing, drying and transporting system for a pulverized fuel of a blast furnace of the type having at least one hot stove for supplying hot blast air, said hot stove also providing hot stove exhaust gas. The system includes a pulverizing and drying unit for pulverizing lamp raw fuel and drying the pulverized fuel. The hot stove gas is supplied to the pulverizing and drying unit. The hot stove exhaust gas dries the pulverized fuel and conveys it to a pulverized fuel collecting and separating device which separates the gas from the pulverized fuel. The line supplying the hot stove gas to the pulverizing and drying unit includes a heating device for selectively supplying additional heat to the hot stove exhaust gas. Moreover, the line for supplying the hot stove gas to the pulverizing and drying unit can include at least one of a temperature stabilizing device and a cooling device. The heating and cooling devices and controlled by a controller sensitive to the gas temperature at the outlet of the pulverizing and drying unit for maintaining the gas temperature at the outlet of the pulverizing and drying unit at a constant level. The temperature stabilizing device maintains the gas temperature at the outlet of the temperature stabilizing device at a designated level.
