Read MoreVertical Shaft Brick Kiln Technology: Cleaner Fuel Makes Better Brick August 13, 2009 by Vertical shaft brick kilns are energy efficient, the initial investment cost is not great, it’s environmentally friendly and they can be used to fire different kinds of bricks.
Read MoreThe alternate to premixing is feeding the kiln by alternate layers of fuel and limestone. However in the type of unmixed-fuel type vertical shaft kiln, the fuel is burnt in a separate box and hot flue gases so produced in the box enter the kiln through holes in the vertical shaft walls for burning the limestone in the kiln.
Read MoreThe 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 ...
