Regardless of tunnel kiln, kiln or firing roller kiln , rotary kiln when abnormal conditions occur when firing , kiln firing various  
indicators and products have a greater theoretical curve changes, and very unstable , firing is not stable product quality .  
Kiln is that there is no abnormal condition caused by a variety of reasons , only depending on the cause , and take the  
appropriate solution, to resolve the situation is not normal kiln arise. Abnormal condition occurs kilns usually have : full kiln  
fire occurs due to the larger temperature difference between the upper and lower section of the kiln , kiln appeared muted  
brick , burnt brick kiln appeared , firing temperature control allowed, preheating zone body resurgence and so on. Today,  
let us YuFeng Heavy Equipment Engineer kiln for your first explain in detail , the reasons for under- fire and method of  
operation should take full kiln appear. Due to fire at full kiln , kiln stack blank red or dark red , fired brick owe the fire,  
mainly the quality of products , low intensity, often said to produce " raw brick ." Cause of the fire was due to the whole kiln :  
Zi, fires, fire engineering degree to master allowed , the small fire to see big, especially at night when there is a large  
difference between the light and day , to see a larger fire temperature differences. Second, when you add external fuel , did  
not follow the "ground Tim ", " little Tim ," " small number" of the principle of external fuel added , resulting in a larger kiln  
heat changes . Zi three fuel ash is too large, low heat, poor quality, according to the amount of investment and the amount  
of coal still good quality fuel , leading to a kiln total calories is not enough, so the kiln temperature can not rise to the  
desired temperature . Fourth , the use of the damper is too high , excessive ventilation whole kiln , the kiln resulting in a lot  
of heat is pumped , can not make the firing kiln temperature to the desired temperature . Fifth, the use of the damper is too  
low , the amount of ventilation in the kiln is too small , no sufficient amount of oxygen caused by the combustion of fuel in  
the kiln , the combustion heat of a low strength per unit time is insufficient to fuel the combustion temperature to the kiln  
desired temperature . Came across the whole kiln due to fire , should take the following methods of operation . To change  
the status of the kiln firing . First, the timely detection of the kiln temperature , accurately grasp the kiln furnace. See the kiln  
temperature trends , determine the kiln temperature to go, or to continued to drop , to provide a reliable basis for adding  
external fuel . Second, when additional fuel must be " watching the fire stokers ", " Qin little Tim Tim ," a few times, adding  
fuel combustion of fuel in the furnace according to the speed , neither can the amount of fuel is too small, not up the  
temperature requirements or excessive fuel quantity can produce incomplete combustion . Third, the accurate knowledge of  
the heat added to the fuel in the kiln , the kiln according to the required heat , fuel, if the fuel calorific value is higher than  
the batch calorific fuels used originally , it should add less . If the fuel heat than the original batch of fuel use low heat, it  
should be more Tim. Fourth, when the whole kiln excessive ventilation , various dampers to quickly lower the entire firing  
operation with positive pressure , that allows each row are firing back with fire , if necessary, the amount of wind is also the  
end of the blank stack should be strictly limited, reduce " after the wind ." After the completion of the operation , you should  
immediately begin to add fuel handling , a small shovel to add low moisture content , dry fuel. If the firing zone all clear at  
the end when you want to add calorific fuel , keep the fire from . Etc. When the kiln fire returned to normal , in order to  
gradually improve the dampers , and Tim still lower ground moisture dry fuel , so before the fire development , and  
gradually to the kiln ventilation, accelerated burning. Fifth, when the full amount is too small kiln ventilation should quickly  
improve individual dampers , so that the whole firing zone is positive , negative working condition, that is, to the front of the  
rear of the firing zone of negative positive , have returned fire phenomenon . At this point , you should increase the amount  
of wind and cold insulation tape , especially the ventilation stack at the bottom of the blank should be increased in order to  
improve the quality of combustion and heat exchange efficiency. Well, today is the first full- kiln due to fire you on the causes  
and methods of operation appears to be taken tomorrow, we will continue to explain " the reasons and methods of
