Description of lime kiln A lime kiln is a kiln used to produce quicklime by the calcinations of limestone (calcium carbonate). The chemical equation for this reaction is: CaCO3 + heat â?? CaO + CO2 This reaction takes place at **0°C (at which temperature the partial pressure of CO2 is 1 atmosphere), but a temperature around ***0°C (at which temperature the partial pressure of CO2 is 3.8 atmospheres) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces uncreative, "dead-burned" lime. Our Lime Kiln features is, convenient and reliable control of the production process, less wearing parts, high rates of operation, The Lime kiln also has strong structure, stable operation, low energy consumption, high-quality products, large capability from the kiln and so on advantages, we can also offer advanced efficient shaft preheated, five grade cyclone preheated. Technical features of lime kiln Take the**0t/d kiln as example. It can be regulated within **0t/d***0t/d range without influencing quality and consumption targets. 2. Chalk size: **0mm to *0 mm. size range ratio is 1:2 3.Kinds of fuel: natural gas, oil, cola dust, coke oven gas, coal gas of low heat value and mixed fuel of all kinds of fuel(gas and gas, gas and liquid. gas and solid, liquid and solid and so on). 1. The kiln body is rectangular or cylindrical. There are double-deck burner girders in the kiln body with periphery burners in the middle kiln body. Waste gas drawing-out girder is set on the kiln top. The kiln is divided into five parts: material storage zone, preheated zone, claiming zone, posterior claiming zone, cooling zone. The part between the kiln gas drawing-out device and the crown is the storage zone. It is used for storing adequate lime stone in order not to stop producing when the crown feed device needs short-term maintenance The part between the kiln gas drawing-out device and the upper burner girder is the preheat
