What is a shadow kiln burning zone adjacent to the rear of the exothermic reaction zone, the material into the band after the release of a chemical reaction in a lot of heat, the temperature rapidly increased to about 1300 ℃, resulting in decomposition temperature of the material and put the belt thermal reaction with the material temperature difference above 200 ℃. The substance at different temperatures, different reflective properties, lime reflection is strong at high temperatures, low reflective at low temperature, the larger the difference in brightness, so we can see dark material of low temperature, high temperature materials shiny . Dark is called "shadow", in fact its temperature is not low, about 1000 ℃ or more. When the temperature difference is small, it has not divided the light and dark, which is reflected in a period of time to stop the kiln, raw clinker on a confusion of the moment. How to see and hold "shadow" position to see the fire in the kiln operation, only to see and hold "shadow" position in order to stabilize the position of firing zone, stable kiln temperature purposes. Find a "shadow", we should see the fire main kiln flame Shaopian hole to see the location of the lower left, then roll to see the burning zone of dark gray material is called "shadow." Some kiln control "shadow" position farther normal see. "Shadow" stuck position, and the length of the flame temperature portion and about burning zone temperature level. Flame temperature mayor, "shadow" on the remote; flame temperature zone is short, "shadow" near. Burning zone temperature is high, "shadow" on the remote; burning zone temperature is low, "shadow" near. Normal firing, the kiln "shadow" position always keep a place in attempting points behind. If the "shadow" run away, indicating the kiln temperature rise, firing zone stretched. If you do not see, "shadow", it may be due to material easy to burn, reduce or incoming wind caused by excessive coal kiln temperature is too high. If the "shadow" moving to the kiln, kiln temperature indicates a declining possible. If the "shadow" coming forward rapidly and extensively described kiln temperature has been low, but also indicates the kiln will have plenty of material coming. Such as "shadow" coming to the kiln, but not the amount, it may be difficult to burn or material shortage caused by the wind coal. Therefore, the operations center must be comprehensive analysis, timely adjustments. Namely in the "shadow" run away, or coarsening whitish color of the fire, immediately reduce coal, in the "shadow" approach, should be stokers and appropriately increases. If stability is maintained, do not move the exhaust; live if stable, slightly off a small exhaust should be to raise the firing temperature; if you do not live in stable, immediately pre-fight "little slow" to avoid channeling material.
