What is the minimum standard temperature for extending the coking time? For the TJL5550D type coke oven, when the designed coking time is 22.5 hours, the standard temperature is 1310–1320°C. If the coking time is increased, what is the minimum allowable standard temperature? It turns out that for the 4.3-meter furnaces in our facility, the standard temperature is required to be no lower than 1250°C. However, based on the trial production data from 5.5-meter coke ovens over one month, it can be seen that when the coking time is 48 hours, a standard temperature of 1190±20°C is sufficient to ensure that the coke cakes are fully matured. What is the minimum standard temperature for TJL5550D type coke ovens? Thank you to all the sea friends! ! !
Our company； The temperature of the side flue should be no less than 950 degrees, while the temperature of the standard flue should be no less than 1160 degrees.
If the coking time is 48 hours, a standard temperature of between 1140 and 1160°C will suffice.
For a 4.3-meter coke oven that has just been put into operation, the coking time is 40 hours; what is the standard temperature?
Regardless of the type of furnace, when extending the coking time, in addition to ensuring proper carbonization, it is also necessary to pay attention to the temperature at the furnace head, so that it does not drop below the crystalline transformation point after coal is loaded. If a 4.3-meter coke oven has just started operation with a coking time of 40 hours, a standard temperature range of 1210–1230 degrees is sufficient.
The coking time for TJL4350D is 26 hours; what should the standard temperature be?
At least 1100 degrees; too low can damage the furnace.
Reply to 4# gyhai4: 1210-1250 is sufficient.
