| titleOfInvention | Apparatus for controlling combustion of hot stove of blast furnace |
| abstract | The present invention relates to a combustion control apparatus for a blast furnace hot stove, the present invention is applied to an apparatus comprising a blast furnace hot stove, a chimney and a first heater installed for the waste water circuit between the hot stove and the chimney to control combustion. A flow rate detector comprising: a flow rate detector for detecting an amount of air supplied to a hot stove; A low flow rate discriminating unit for determining whether the detected flow rate of the flow rate detector is smaller than a reference flow rate; A differential pressure detector detecting a front and rear differential pressure of the first heater; A flue differential pressure control section that calculates a control amount corresponding to a difference between the detected differential pressure of the differential pressure detector and a differential pressure with a first reference differential pressure; A high differential pressure judging unit for determining whether the detected differential pressure of the differential pressure detector is higher than a second reference differential pressure; A switching circuit unit for switching the output of the flue differential pressure control unit during low flow rate discrimination of the low flow rate discrimination section and high differential pressure discrimination section of the high differential pressure discrimination section; A converting unit converting a control amount of a flue differential pressure control unit into a valve operation amount through the switching circuit unit; A differential pressure control tube connecting front and rear ends of the first heat; It is provided in the differential pressure control pipe is provided with a differential pressure control valve for adjusting the opening ratio of the differential pressure control pipe according to the output value by the conversion unit, according to the present invention, the front and rear of the heater installed between the blast furnace hot stove and chimney When the pressure difference occurs in the stage or more than the set value, by opening the feedback connecting pipe provided in the front and rear ends of the heater in accordance with this pressure difference, it is possible to prevent excessive pressure increase of the flue side during combustion in advance to enable optimum combustion control. |
