Lime kiln technical characteristics: (1) the combustion air is divided into primary and secondary air. Primary combustion air directly involved in the secondary air to the cooling air. Primary and secondary air are supplied by a single fan. The design of the secondary air temperature can rise up to 600 ℃, lime kiln risk, as combustion air, lime kiln company, in order to save fuel provide favorable conditions. (2) the use of special combustion system to rotary kiln heating, energy-saving kiln, in addition to using pulverized coal as fuel outside the low calorific value gas can also be used alone (eg, producer gas, calcium carbide exhaust, semi-coke gas) as fuel firing, the kiln , using a variety of fuels may be supplied simultaneously used. The calcination temperature can be adjusted by adjusting the air and gas flow. (3) measures to improve environmental protection. Calcination exhaust using pulse jet bag filter dust, to meet the national emission standards. In the vertical blanking point cooler it is also used baghouse dust. (4) high level of automation. Calcining system equipment manufacturing operations of regulation, control and alarm using PLC (programmable logic controller) in the main control room centralized control, and a screen display of the control points and the necessary interlock monitoring of the production process used in the operation parameters are automatically recorded and can be printed at any time. Burning one ton of lime required by theoretical calculations 1.78 tons of limestone, but when firing "Health", "too" burn limestone quality level and there is a certain difference between good and bad. 6 quicklime quality standards: Edit the lime quality general criteria are: calcium oxide content, raw, over-burning rate, degree of activity, and other harmful ingredients, but more important is the different industries, different standards have different purposes. Such as calcium carbide industry it highlights the degree of activity that is soft burning ash, iron industry, it emphasized that the strength, so hard burning ash, steel is again the soft burning ash. So it is not the same index. General standard lime, calcium oxide content to reach more than 97% burn rate given birth less than 10% active calcium to 300mi more.
