PURPOSE:To eliminate a loss of transporting motive power and to improve a property of maintenance, by measuring a distribution flow rate of mixed fuel basing on the measured value of a pressure loss caused by piping provided for distribution of the mixed fuel. CONSTITUTION:A main pipe 1 is branched to branch pipes 31, 32-3N in order to distribute and supply to a tuyere of a blast furnace after passing the mixed fuel supplied from a supply source through a standard flowmeter 2. Each pipe 31, 32-3N is provided with pressure loss measuring instruments 41, 42-4N and thermometers 61, 62-6N. Calculation processing of these measured value is carried out by K value temperature correction devices 71, 72-7N, flow rate rough estimate devices 51, 52-5N, a correction factor calculation device 8 and a flow rate calculation device 9 and the flow rate of each branch pipe 31, 32- 3N is indicated by an indicator 10. |
