When the clinker in the rotary kiln is calcined, proper flame and proper temperature distribution in the kiln are maintained.
When the clinker in the rotary kiln is calcined, proper flame and proper temperature distribution in the kiln are maintained. The quality of the clinker produced, the quality of the kiln, thekiln skin thickness and length, kiln lining life, fuel consumption, pollutionreduction and environmental protection are both very important role. Therefore,the cement rotary kiln has strict requirements on the flame, especially in thenew dry rotary kiln flame shape, temperature and strength requirements, and therotary kiln calcined clinker compatible to ensure that the entire flame lengthcan be highly efficient heat exchange at the same time cannot make the kilnskin produce local overheating, appear the peak temperature, should be able toadapt to the change of kiln situation. To meet these requirements, you should have the following:
(1) The amount of air supply to the primaryair should be as low as possible, and the mixed air should be sufficientlymixed to make full use of the high temperature secondary air to achieve thepurpose of energy-saving and energy-saving. The old-fashioned single-channelcoal injection pipe for technological transformation, or multi-channel coalinjection pipe instead of single-channel coal injection pipe to reduce theamount of primary air.
(2) Combustion efficiency and burnout rateof pulverized coal are high, to avoid clinker quality decline and processaccidents due to incomplete combustion.
(3) The shape of the flame is stable andwell-suited to the changing needs of the kiln. The distribution of thetemperature field in the kiln is reasonable, avoiding the appearance of peaktemperature and no pulse of flame.
(4) The flame shape of multi-channel coalinjection pipe is convenient and flexible to adjust according to needs.
