How to use lime kiln waste heat

The qualified raw materials and fuel in proportion, with an accuracy of three percent said electronic accurate weighing, hopper and belt conveyor through the middle

uniformly mixed by 1.5m3 bucket hoist along the bridge of a single mixture delivered to the roof by the hopper, electromagnetic vibrating feeder evenly through the

dosing by rotating distributor to complete the furnace roof fabric. Material flow by gravity to overcome the buoyancy of the gas and slow down the movement, have

passed the preheating zone, calcining zone, cooling zone. Charge during descent, with the hot gas for a complex heat exchange, and accompanied by decomposition

of limestone and lime development of the grain growth process, when the entire process is completed, the combustion air can be cooled down to 40-60 ℃ . Then the

ash from the disc drive and two sealing valve does not leak combustion air in the case of lime to the furnace unloading belt conveyor. The upgraded machine,

screening, will be ≤ 5mm and> 5mm lime were unloaded into separate bins. Combustion air from the blower from the furnace bottom blown into the furnace, to

overcome the resistance of the pellets from the bottom up to the roof, in the dust, attracted by the induced draft fan, flue gas through the pipeline to dust to dust. As

the role of the induced draft fan, so that the formation of micro kiln feed side surface of the negative pressure region (-10Pa or so). The slightly negative pressure to

ensure the smooth flow furnace, is very conducive to the decomposition of limestone calcining zone, flue gas fan will be fully introduced filter purification, and then

discharge from the chimney into the atmosphere. The above article by Henan YuFeng Heavy Machinery finishing release, reproduced, please indicate the source!
