IPC: C21B5/00
Filed: 1984-07-26
Abstract: PURPOSE:To achieve advantageously the cost decreasing still further while ensuring stable operation, by interposing a prescribed quantity of cokes of an ore layer, in all cokes operation in which the ore layer and a cokes layer are charged into blast furnace alternately and hot air is blown from tuyere. CONSTITUTION:The ore layer 1 and the cokes layer 2 under a prescribed ore/ cokes ratio are formed alternately in the blast furnace 10 and the all cokes operation is carried out. Thereat, cokes corresponding to 5-25% total quantity of charged cokes is charged in the layer 1 as the interposed cokes layer 3, hot wind is blown from tuyere, and the operation is performed. In concretely, raw materials are charged dividedly as each charge of ore and cokes in such a way. By this method, the layer 3 as gas passage layer is ensured in the ore layer at softened sticking zone of lower part of blast furnace, and the heat exchange with gas at said sticking zone is improved. Thus, stable operation is possible even under low fuel ratio condition.

Title: Steam trap
Inventor: EMA GENZO
IPC: F16T1/00
Filed: 1989-06-15
Abstract: PURPOSE:To ensure accurate control as well as to decrease cost by detecting a water level in a controlled fluid and its temperature with electric energy made up of converting kinetic energy of the controlled fluid, and controlling an operating valve so as to exhaust a noncondensing gas without discharging any steam. CONSTITUTION:Kinetic energy of an outflow fluid is converted into electric energy by a generator 7 connected to an outlet 9 of a vessel, and this electric energy is stored in a storage battery 13. A control circuit 9 and a motor-driven valve 6 are driven by the electric energy stored in this battery 13. If a water level in a chamber 3 goes up to an upper level sensitive electrode 17, the motor- driven valve 6 is opened, and if it goes down up to a lower level sensitive electrode 16, this valve is closed. In addition, a diode 14 prevents the electric energy stored in the battery 13 from flowing back to the generator 7 when this generator 7 comes to a stop. Thus, since the motor-driven valve is driven by the electric energy, control is accurate enough and there is no change with the elapse of year, no steam leakage, and no malfunction so that production cost is reduced.
