Why is cold coke placed in the dry quenching furnace when using gas for heating?
Thread Content
Laying cold coke in the dry quenching furnace in advance during gas heating is mainly to protect the central air cap at the bottom, the surrounding air intake devices, and the lining from thermal radiation. At the same time, if there is no pre-cooling step using cold coke, the red coke will directly enter the coke discharge device during loading; the circulating air will be unable to provide cooling, which may damage the discharge device. Are there any other possible reasons?
When red coke is introduced, cold coke can act as a barrier, preventing the red coke from coming into direct contact with the bottom of the dry quenching system and the discharge devices, thereby avoiding damage to the equipment. Does it count?
Another important reason for loading cold coke into the dry quenching furnace during gas heating is to improve thermal efficiency and accelerate the cooling process. Cold coke can be used as a heat exchange medium to help absorb the heat released from hot coke, thereby reducing its temperature more quickly. This not only saves energy but also improves production efficiency. Furthermore, the presence of cold cokes helps to reduce the dust and smoke that may be generated by hot cokes during the coke quenching process, thereby improving the working environment and reducing environmental pollution. At the same time, the laying of cold coke also helps to maintain uniformity of temperature inside the coke quenching furnace, preventing damage to the furnace due to excessive temperatures. .
