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, lime kiln, limestone poor uniformity, kiln generate tumor masses or local exhaust ventilation is poor. 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, Fukasawa lime kiln, but also make certain prolonged firing zone. This occurs when the proper cut, 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. On asphalt fume treatment had a "clay adsorption" process, gaoyi lime kiln, which uses clay to absorb asphalt fumes, smoke pollution clay after incineration. This process is complicated, high operating costs, Zanhuang lime kiln, and there is no secondary pollution problems, the actual operating results are unsatisfactory. Some enterprises according to their own conditions, asphalt smoke by burning method, the process is simple. Now some products using organic binders, emission of harmful substances during the heat treatment, but also by burning gas method, the gas burned in the stove, the burning temperature> 750 ℃, combustion volume heat intensity around 1300GJ / m3h. Over the years, in the part of the oil facility with a "wash oil absorption" technology. The use of wash oil absorbing asphalt fumes, the process shown in Figure 1. Bitumen Gas wash oil absorption saturation can be used as fuel other furnaces, reduce costs, put into better use.
