Third, extend the firing zone, firing zone extended temperature will cause the top and gray are high temperature, CO2 decline, lime green burn the same amount of increase, serious fire at the top of the kiln red ash, which is two to see red. Kiln generate tumor mass or poor local exhaust ventilation, because the fuel ratio is too large, limestone, poor uniformity, kiln generate local tumor masses or poorly ventilated. At the same time there is nodulation kiln or kiln wall material, ventilation segregation, nodules or hanging material at the material can not impede the normal fall and poor ventilation. Because tumor block off under the impact of material flow, but also make certain prolonged firing zone. This occurs when the proper cut, kiln firing size adjustment of raw materials, reducing fuel ratio appropriate to increase the amount of wind. Temporarily reduce the material layer height and then feed back to normal material surface. (1) reducing the amount of wind pressure and the fire floor down, such as the top of low pressure may be appropriate top pressure. (2) increase the amount of cinder, due to increase fuel ratio, supplementary heat loss is not restored to normal when the top temperature is high due to normal after adjustment for normal. (3) examine and adjust the size of the original fuel. The fuel content limit excessive powder, may be appropriate to add the water to saturation, so that they increase the degree of cohesion stone to delay the fuel burn time. Firing zone down, wind, fire, when finding the top temperature is low, gray temperature rise, serious and wind unburnt fuel. The same raw lime burning increased while reducing CO2 concentration which shows a firing zone down. The main reason for this situation is the small amount of wind, Shangshih volume, cinder large lime kiln plant, mixing down so fast, and shorten the cooling zone, failed to sufficiently preheated air will enter the firing zone, leaving the carbonate reducing the number of calcium decomposition, CO correspondingly reduced. Cause an increase in the amount of burned lime green. Another is the raw material crushed or size bias large deviation increase kiln resistance, this time pressure is not low, but the actual amount is not enough wind. In such cases should be appropriate to reduce the amount of loading and unloading stone kiln ash soil, appropriate to increase the amount of wind, so when the top pressure is too large, may be appropriate to reduce the material batch, changing the material partial pieces, the appropriate increase in the proportion of large grain blocks reduce grain differential, so the kiln resistance decreases. Adjustment of fuel and stone blocks to make it meet the technical requirements. Limekiln | kiln | Sky furnace by LUOZHUANG Kiln Ltd. Linyi City blue sky.
