Regarding the steps to stop heating the 5.5-meter ramming coke oven
Thread Content
The heating-stop steps have been simplified in the procedures; could someone please list the steps for stopping heating for a short period of time and for a long period of time?
For a short period of time? Ask the switch operator in advance to adjust the switch cock to the middle position, thereby reducing the suction force in the flue. For a long period of time? Do the same thing, and ask the temperature tester to close the adjustment valves again.
To stop heating for a short period, simply close the exchange valve. Stop heating for a slightly longer period of time; also close the adjustment valves in order to reduce the suction in the flue and decrease the air intake ； After a longer period, stop heating and close the valve on the main gas supply
He wants to ask that very little gas is produced, so heating isn’t necessary; the blowers used for recovery have difficulty operating and fail to reach their critical speed
