What precautions should be taken when using blast furnace gas to heat coke ovens?
The main safety concern is preventing poisoning. The heating process is similar to that using coke oven gas; in my opinion, the key aspects to pay attention to are the suction force at the top of the furnace and the temperature at the furnace tip. If the suction force is adjusted properly, heating with blast furnace gas will be quite stable, but the response to changes in gas temperature is slow, so it’s not advisable to increase the temperature continuously in a hurry ； When using blast furnace gas for heating, the temperature at the burner tip is generally low, and this needs to be addressed promptly.
1. The sealing of the furnace body is important, as the main component of blast furnace gas is CO, which is highly toxic and odorless, posing a high risk of safety accidents. 2. Ensure the sealing of the regenerator enclosure walls, flues, and actuators. 3. Ensure that the dust content in blast furnace gas is below 50 mg/l, to prevent dust buildup that could clog grid bricks and 1-meter pipes and other components. 4. The pipes and heating system need to be purged regularly.
Their calorific values are different; pay main attention to changes in the burner temperature
