The working principle of the multi-channel burner of the rotary kiln
The working principle of the rotary kiln burner: When the reaction temperature is low, a combustion chamber is set beside the kiln head cover to pass hot flue gas into the kiln to supply heat. In the early days, the burners in the rotary kiln mostly adopted a single air duct structure. The primary air volume accounted for about 20% …
