DAMPER PLATE CONTROL DEVICE OF WASTE GAS VALVE IN COKE OVEN

摘要

A device for adjusting a damper plate of a waste gas valve in a coke oven, which can reduce material cost as well as combustion management cost by replacing a portion of the damper plate only within a short time in the state that the damper plate is installed when maintaining the damper plate of the waste gas valve, is provided. A device for adjusting a damper plate of a waste gas valve in a coke oven comprises: a main body(1) for forming the body of the waste gas valve; a damper plate(2) mounted within the main body and vertically adjusted by adjusting of a control bar(4); a first shaft(5) supported to one side of the main body to connect the damper plate; a second shaft(6) supported to the other side of the main body to connect the damper plate; and an indication plate(3) which is connected to the first shaft through the control bar and displays a pressure adjusting numerical value, wherein rectangular guiding grooves(2a,2b) are formed on portions of the damper plate connected to the first shaft and the second shaft respectively.
