Initial Considerations kiln firing

Article source：

Before kiln firing after all preparatory work properly, check the kiln does nobody, and with the auxiliary contact a good job, you can be ignited. Start the ignition is

not required to open the exhaust fan, simply open the kiln gate, with natural ventilation, not through the ESP, without spare chimney can also be the ESP, but the

non-transmission, timber after stoke, once the wind and Trace into coal, then gradually increase, according to whether the pulverized coal ejected falls wood

woodpile then adjust the flame temperature zone one, two, second wind. When most of burning wood finish, firebrick shiny surface, the first rotary kiln 1/6 turn, but

also full turn, but can not be transferred, to prevent the fire is out. After the kiln temperature gradually increased every 3-5 minutes once the rotary kiln, rotary kiln

every 1/4 turn until the firing zone firebrick surface heat evenly, gradually increasing a secondary air, coal spray into the kiln flame has formed, you can open the

exhaust fan, exhaust fan opening prior to gate off a small kiln, exhaust fan out later, and then adjust according to the length of the flame kiln gates. After opening

the exhaust fan, kiln temperature gradually increased, when the dry kiln reaches about 500 ° C, wet kiln reaches 120-160 ° C, the continuous operation of the kiln

can be slow, and began feeding, the initial volume of feed as normal 50-70% of the volume of feed, feeding machine should be synchronized with the kiln speed,

the fastest first class kiln speed is 50-70% of normal kiln speed, the material yet to come before the firing zone, the basic method of operation is leaving the fire,

heat to be expected at this time pay attention to controlling the burning zone temperature should not be too high to prevent damage to the bricks, but do not fire,

keeping kiln is dark red, until the raw material coming firing zone, the only appropriate increase in firing into temperature. The above article by Henan YuFeng
