Solutions to low temperature of ammonia water in the coke oven cycle
Thread Content
The reduction in coke oven production has prolonged the coking time. However, here’s the problem: the current atmospheric temperature is between 0 and 10 degrees, the temperature of the circulating ammonia water is too low at 60 degrees, and the temperature of the gas collection ducts is 70 degrees. It’s likely that the temperature will drop even further. I’m asking those with expertise if there are any solutions.
Reduce the ammonia water circulation volume and the amount of gas in the large circulation system.
What is the gas temperature before initial cooling now?
I’m sorry; I had something to attend to and couldn’t visit the forum those days. These days, the gas temperature in front of the pre-cooler is 70 degrees. What concerns us now is the further drop in temperature, which could cause blockages in the gas collection pipes or negative pressure pipes.
Steam inlets are provided at both ends of the gas collection pipe; when the temperature of the gas collection pipe is low, low-pressure steam can be introduced to appropriately raise its temperature； It can also reduce the amount of recycled ammonia water used and maintain an appropriate temperature in the gas collection duct.
