求翻译：炉内结焦，主要现象是沸下温度增加，沸上温度下降，炉膛负压增加且波动微弱，这时应降低负荷、停炉，打开点火炉门，清除焦块如无效则立即停炉是什么意思？

Furnace coke, the main phenomenon is under boiling temperature increases, the boiling temperature drops, the furnace negative pressure increases and fluctuations in weak, then the load should be reduced, shutdown, fire door open, clear focus, such as an invalid block is immediately shutdown

furnace, coke, major phenomenon is convinced that the temperature increase, convinced that the temperature increase and decrease in negative pressure fluctuations1100faint, and this should be lower the load point, oven stoves, open door, remove scorched piece immediately if invalid oven

In the stove cokes, the main phenomenon is boils the temperature to increase, boils the temperature drop, the chamber negative pressure increase also the undulation is weak, by now should reduce the load, the blowing-out, opened the ignition fire door, eliminated Jiao Kuairu invalid then immediately

Furnace Coke, the main phenomenon is boiling temperatures increase, on the boiling temperature falls, furnace pressure increase and fluctuation of weak, you should reduce the load, shutdown, open furnace doors, clear the coke pieces such as invalid immediately shutdown

Furnace Coke, the main phenomenon is boiling temperatures increase, on the boiling temperature falls, furnace pressure increase and fluctuation of weak, you should reduce the load, shutdown, open furnace doors, clear the coke pieces such as invalid immediately shutdown
