What are the advantages and disadvantages of gas introduction at the furnace head and gas introduction at the furnace tail in the low-temperature pyrolysis of coal powder rotary kilns?
For low-temperature pyrolysis in coal powder rotary kilns, it is generally reasonable to supply air at the furnace outlet; this helps to create an appropriate atmosphere inside the furnace, preventing oxygen from entering along with the feed material. As a result, the loss during combustion is reduced, and the amount of ash produced is less!
