Rotary kiln and the preheater 12 common problems and treatment

Rotary kiln and the preheater failure phenomenon : running raw material reasons: a kiln temperature drops too much , too 
little to feed coal ; 2 preheater collapsed material , raw material into the firing zone , sprang kiln . ; 3 attempting to be 
compressed raw material , kiln temperature drops , kiln vacuum fluctuations , the current decline in the kiln , kiln hair muddy 
, grate under high temperature kiln , cooler take the ash disposal methods: 1 minus feed, less kiln speed ; 2 when running a 
harbinger raw or raw material pre- run , may be appropriate to increase coal. When running the raw material has become a 
reality , kiln temperature drop is large, should be appropriate to reduce the feed to feed coal. When the firing zone to be 
current, and temperature rise, feeding can improve kiln speed , feed rate should not be too large. Rotary kiln and the 
preheater failure phenomenon : the collapse of material preheater reasons : 1 total exhaust volume suddenly dropped ; 2 
cone negative sudden drop ; 3 kiln temperature had dropped ; 4 Kiln negative . .. pressure decreases, positive pressure 
treatment: a large collapse raw material by running troubleshooting , small collapsed kiln feed material may be appropriate 
to increase the coal, or no treatment . Rotary kiln and the preheater failure phenomenon: the collapse Circle ( off kiln skin ) 
reasons : 1 kiln current rise quickly in a short time ; 2 kiln kiln visible dark skin ; 3 local high temperature treatment may 
occur : 1 to adjust the flame temperature point , the flame smooth , vacuum kiln heat is not too high ; (2) appropriate to 
reduce kiln speed , can be slow to recover normal kiln kiln speed ; 3 adjustment carcass cooling fan rotary kiln and 
preheater appear Symptom : Preheat cone blockage causes: a cutting wind flap valve channeling long-term , lower cone 
crust ; 2 calciner incomplete combustion of pulverized coal , the material viscosity increases gradually accumulate in the cone 
, not . timely and clear blocked ; 3 cone vacuum drastically reduced , cutting the temperature drops , the outlet temperature 
rises approach : blocking material has happened to stop by the order to stop the kiln kiln , kiln stopped within four hours of 
the prohibited method to pull the wind blocking material handling artificial poke blocked . Rotary kiln and the preheater 
failure phenomenon: the temperature indication error big reason : a thermocouple material paste is live ; 2 thermocouple is 
blown approach : .. 1 clean- product material ; 2 replacement thermocouple kiln and preheater failure phenomenon : a low 
pressure indication reasons : 1 piezometer is dust clogged ; 2 cyclone plot material processing methods : 1 purged with 
compressed air piezometric ; 2 purged with compressed air . Ministry cone cyclone preheater kiln and failure phenomenon: 
the rise of flue crust reasons : 1 alkali , chlorine, sulfur and other harmful ingredients contained in the raw material ; 2 high 
kiln temperatures ; 3 severe reduction kiln atmosphere ; 4 thermal system unstable systems approach : 1 cleanup crust ; 2 
timed use of air guns ; 3 adjust the calciner feed ratio of four cylinder ; 4 prevents the kiln to produce a reducing 
atmosphere ; 5 . strengthening Yuanrancailiao prehomogenization rotary kiln and preheater failure phenomenon: the kiln 
ash reasons to take seals : a rise in the flue crust ; 2 kiln slope plot material ; 3 kiln material filling rate . .. Extremely high 
processing methods: a clean-up crust ; 2 clean-up slope plot material ; 3 to reduce or stop the feed material , increase 
speed rotary kiln and the preheater kiln failure phenomenon : . cleanup crust reasons: 1 Yaotou . positive too ; 2 ran raw 
materials ; 3 snowmen cooler approach : a slowdown in the speed of the grate bed , increase kiln ventilation ; 2 Less 
material, less coal, less wind , large climbing ; 3 . see cooler " snowman " Troubleshooting kiln and preheater failure 
phenomenon: the occasional round oiler high temperature causes: a lack of cooling water ; 2 poor oil processing methods : 
1 increase cooling water ; 2 . clear the oil preheater kiln and failure phenomenon: the high temperature kiln shell reasons : 1 
out kiln skin ; 2 firebrick thin ; 3 burning zone temperature is high ; 4 kiln feed rate value improperly . .. kiln hard skin 
hanging ; 5 out firing with cause red brick kiln processing methods : 1 mobile cooling fan, cooling the high temperature 
zone ; 2 regulate coal burner fire points inside and outside the wind changed as cylinder temperature higher than 400 ℃ yet 
. there is an upward trend , relining of the kiln ; 3 to ensure raw material decomposition rate , reducing kiln pressure ; 4 
aluminum ratio improved to enhance burning zone temperature, kiln speed , feed amount lower ; 5 stops up the brick kiln . 
Rotary kiln and the preheater failure phenomenon: the kiln shell temperature is low Cause: Kiln thick skin treatment methods 
: 1 kiln fight Express ; 2 to change the kiln feed rate value , improve the value of silicon , aluminum lower rate . . Please
