What is the circulating air volume in the dry quenching technology?

This post was last edited by Desert Poplar on 2011-2-27 at 17:13. Everyone, please share what the circulating air volume for the dry quenching process in your factory is
Circulation fan capacity: Baosteel 125m3/h； Yahata 210m3/h ； Kunito 245 m3/h. Excerpt from Coal Chemical Engineering Technology. Things may change as it develops; I hope everyone will point out any errors.
For completeness, the unit is km3/h
The selection of the circulating fan for the dry quenching system is determined by the process parameters, namely the volume of circulating air, which in turn depends on the size of the dry quenching system. For example, the circulating air volume for a dry quenching unit with a capacity of 75 tons per hour is 110,000 Nm3/h, and so on.
Wow, they’re so big. At our plant, the 75T dry quenching units have their air valves set at 22–25, with an air flow rate of between 8W and 9W; if the valves are opened any further, it will block the chute.
The circulating air volume is related to the coke processing capacity; the specific ratio is what we commonly refer to as the gas-to-coke ratio. The design value is generally 1250; for example, in a coke dry quenching unit with a processing capacity of 75 t/h, the circulating air volume is 1250 x 75 = 93750. However, it would be good if the gas-to-material ratio could reach 1350. Domestically produced dry quenching units generally have a higher performance than those of the 1250 model, and this is related to factors such as equipment quality, construction and commissioning, and operational skills.
The so-called 75t/h, 150t/h, etc., refer to the rated processing capacity; the actual processing capacity is determined by the hourly output of the coke ovens upstream.
What factors need to be considered when placing an actual order? Thank you!
The sizes of the stoves vary, and so does the amount
The current air flow rate for the 150T dry quenching unit in our plant is around 199,000.
