OPERATIONS STRATEGIES FOR VERTICAL SHAFT LIME KILNS
The next common type of kiln is the vertical shaft kiln. This kiln can be described as an upright heavy steel cylinder lined with refractory material. The limestone is charged at the top and is calcined as it descends slowly to discharge at the bottom of the kiln. A primary advantage of vertical kilns over rotary kilns is the higher fuel These included the Hoffman Kiln Bull trench Fixed Chimney Bull Trench Zig Zag Down Draught Vertical Shaft Brick Kiln Shuttle and Tunnel. The other widely used intermittent kiln is the down draught kiln in which the bricks are fired in batches. In this kiln the hot gases from the burning fuel are first deflected to the roof of the kiln

Many of these kilns put out 10 000-15 000 bricks per day (this figure may refer to a 2-shaft kiln). Quality is very high and brick wastage is very low when compared to other kilns being only 2-5 in China. The firing process is completed in about 24-30h as the bricks move from top to bottom. One batch is removed at the bottom at a regular The quality of brick made in vertical shaft kilns is better than that fired in coal-fired furnaces with 8-10 percent of the brick made being substandard as opposed to 15-20 percent in the traditional furnaces. After the demonstration models were shown to be a success vertical shaft kilns were built in more than 20 provinces and municipalities
