摘要： PURPOSE:To obtain semi-carbonized coke, in high thermal efficiency, without causing the cracking of the coke, by partially carbonizing green briquette utilizing the sensible heat of the gas exhausted from a reducing furnace after the reduction of iron ore, and carbonizing the briquette again with a hot reducing gas. CONSTITUTION:The fuel blasted through the tuyere 4 is converted to a hot gas composed mainly of CO and H2 in the coke layer (b), transferred upward through the gaps in the layer (b) to melt the partially reduced iron, etc., and recovered from the gas-outlet port 3 as a hot reducing gas. At the same time, the produced molten iron, etc. is made to contact countercurrently with the ascending gas in the gaps, and the iron oxide in the molten slag is reduced with coke to molten iron. The produced molten iron and slag are discharged through respective discharging port. The gas 12 composed mainly of CO and H2 and taken out through the outlet port 3 is blasted into the iron ore reducing furnace 14 and the recarbonization furnace 17 for the semi-carbonized coke to reduce the iron ore 15 in the reducing furnace 14. The gas 18 exhausted from the reducing furnace is used for the partial carbonization of the green briquette.

摘要： PURPOSE:To measure the flow rate of a powder body stably and highly accurately, by detecting the pressure loss of the mixture of the powder body and a carrier gas when the mixture passes a bent pipe part, detecting the flow rate of the carrier gas, and computing the flow rate of the powder body. CONSTITUTION:A powder body, which is supplied to a straight pipe part 3a of a transporting pipe 3, is carried by a carrier gas, which is supplied through a carrier gas supplying pipe 4, and sent to a required place through a bent pipe part 3b. An operating part 9 reads a pressure loss DELTAPSG of a solid and gas mixture fluid at the bent pipe part 3b from a differential pressure gage 5, and also reads the pressure, temperature, and flow rate of the gas from a pressure gage 6, a thermometer 7, and a flowmeter 8. The operating part 9 computes the pressure loss DELTAPG of the gas at the bent pipe part 3b and the mass flow rate WG of the gas. Since DELTAPSG/PG is the function of only a ratio (m) between the mass flow rate WS of the solid and the mass flow rate WG of the gas, the mass flow rate (m) (a) is computed by a specified conversion expression, and the mass flow rate WS of the powder body is computed.
