Stop firing system , in the absence of unforeseen circumstances occur , should be carried out in a planned manner to stop 
the kiln , while the relevant departments need to cooperate to achieve the requirements of the various departments and 
orderly operation by firing , in particular coal warehouse is empty , how much pulverized stay cool for kiln operation should 
be coordinated better. Due to coal vertical combination crusher and bituminous coal stove ignition system is not used , so the system is open to stop 
, and adjust the process to stop the kiln system operating parameters , coal warehouse stock and the next time the kiln 
should be careful consideration and deployment. 1 , two hours before the scheduled flameout , reducing raw material 
supply , calciner gradual reduction of coal , and then gradually reduce the raw quantity, to prevent the ultra-high 
temperature preheater system . 2 , cold slowly open the valve , the high-temperature turbine inlet temperature does not 
exceed 400 ℃. 3, when the decomposition furnace outlet temperature was lowered to 600 ~ 650 ℃, the material is 
completely ended , while reducing kiln speed to 0.5r/min, control kiln the amount of coal . 4 , reducing the temperature fan 
pull the wind . 5, with less wind while reducing coal kiln Hey , do not make the raw material out of the kiln . 6 , stop 
conditioning tower water, and then continue to reduce wind. 7, when the temperature drops below the tail 800 ℃, stop 
feeding the coal kiln , and then stopped high temperature fan , cold air valve is fully open , controlled exhaust fan with a big 
bag kiln inlet valve with the amount of wind. Note that after stopping coal kiln , the need to maintain the necessary amount 
of wind , to prevent coal injection tube deformation. 8 , as the case may stop cylinder cooling air handling units , cooling fan 
seal kilns . 9 , stop kiln big bag , back ash conveying system, raw material feeding system . 10 , when the rotary kiln shell 
temperature of less 250 ℃, change the auxiliary transmission rotary kiln . 11 , after the kiln flame, attention kiln hood 
negative control , a reduction of soy cooler air , kiln exhaust fan exhaust . 12 , when the kiln discharge rarely stopping cooler 
, after some time , six to a room from the room one by one for each fan stop . 13 , stop kiln electrostatic precipitator , 
clinker conveying , a fan , kiln electrostatic precipitator exhaust fan , exhaust fan control with kiln dust collector vacuum kiln .
