The lime kiln is fired with coke air is blown in to provide oxygen for the coke to burn in so that it releases the heat needed to decompose the limestone quicklime from the bottom of the kiln is converted into slaked lime in the slaker and then is passed to the lime still where ammonia is regenerated from the ammonium chloride solution
