Coal Fuel Rotary Kiln with Various Output and Length for Sale
Coal with low volatile content is not easy to catch fire. Long black flames will appear in the kiln, and the high-temperature zone is more concentrated. In order to make the flame of the coal-fired rotary kiln longer and the calcination more uniform, the volatile content of coal is generally required to be between 22% and 32%. Ash. The ash ...
Burning alternative fuels in cement kilns
The main problem with the use of secondary fuel at the main burner is in the often insufficient residence time of the alternative fuel during the flight phase. Due to the horizontal flow in the rotary kiln, the particles follow, in contrast to the use case in the calciner, rather a ballistic trajectory (Fig. 3 and 4). This can indeed be ...
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% …
