Vertical Shaft Brick Kiln - Open Source Ecology

This operating principle is similar to that of a vertical shaft lime kiln. Cold air entering at the bottom cools down the descending (fired) bricks, is then used for firing, then warms up the still-cold bricks on top of the stack. Bricks are loaded at the top and removed at ground level in a continuous process (see animation below for details).Vertical Shaft Brick Kiln - YouTube,07.02.2013· The primary objective of the South Africa Vertical Shaft Brick Kiln (SA-VSBK) project is to introduce and disseminate the VSBK brick firing technology as a v...firing of vertical shaft brick kilns,The Vertical Shaft Brick Kiln Humanitarian Library.

The VSBK is a continuous updraught kiln that contributes towards a significant reduction in energy consumption during the brick firing process, by more than 50%, resulting in reduced carbon emissions, fuel consumption, manufacturing costs and minimal wastage. The VSBK originated in China in the 1970’s. Through the support of SDC,TECHNOLOGY OF VERTICAL SHAFT BRICK KILNS FOR PRODUCING,The inner side of the firing shaft is lined with refractory bricks to provide maximum heat resistance as well as to ensure exact verticality for trouble free operation.

Operation is round-the-clock and annual production of up to 60 lakh bricks has been achieved from commercial VSBK’s operating in India and across.Vertical Shaft Kilns - HarbisonWalker International,Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven off, leaving calcium oxide, also known as quicklime.
