タイトルまたは説明

Mixed fuel vertical lime kiln generally refers to the lime kilns using solid fuel, including: coke, coal as fuel. The so-called new environmental friendly energy-saving mixed fuel lime vertical kiln refers to the reasonable ratio of height to diameter, can realize the three-sections thermal process of preheating zone, calcining zone, cooling zone. The fuel energy can make full use of, and the whole operation process of feeding on the kiln top and discharging at the kiln bottom is closed, the flue gas is exhausted from the pipeline through the dedust, which achieves the non-pollution emission. From feeding, distributing, material level and temperature detection to discharging all are mechanization or automatic operation and control. It adopts a variety of patent technology, which can achieve energy saving and environment protection.
The main structure of new mixed-fuel lime kiln is including the kiln shell, refractory lining, the kiln top charging equipment (rotary distributor), feeding bridge (or hoist), feeding cart, air supplying system (fan, simulated hood), discharging device, dedust device and draft fan.
New environmental friendly energy-saving mixed-fuel lime kiln, its main advantages are low energy consumption, high productivity, good quality, and the  CO2consistency of the off-gas on the kiln top is high, convenient to recycle for producing light calcium carbonate, by which it will reach harmless, no pollution. Lime transmission can select the sealing belt without supporting rollers.
Automatic control is an important characteristics of new environmental friendly energy saving mixed-fuel lime kiln, its feeding, distribution, air supply, gas supply, discharging are all completed by the computer automation control.
