Vertical Shaft Brick kilm - Energy Efficiency By piloting and disseminating an energy efficient brick production technology using vertical shaft brick kilns CO2 emissions can be reduced by more than 100 000 tons per year in South Africa.
and then fired in a kiln. The bricks are fired either in intermittent kilns e.g. clamps; or in continuous kilns e.g. Bull’s Trench Kiln. This thesis deals with the study of energy utilisation in two continuous kilns — Bull’s Trench Kiln (BTK) and Vertical Shaft Brick Kiln (VSBK). BTK and VSBK are natural draught kilns.
of kiln currently operating in the rural areas of China. Many more are presently being built each year to meet the large demand for building materials during the country's current "free market" expansion. (For more information on the vsbk refer to "The Vertical Shaft Brick Kiln" 1995 Techni- cal Brief of this Wall Building Series).

VSBK (Vertical shaft brick kiln) has a long history of evolution. The technology was first born in China. It is not known when the technology was seeded but statistics reveal that this technology came into being between 1968 and 1973.
Vertical Shaft Brick Kiln - Benefits 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.
First successful firing of bricks in vertical shaft brick kiln A few decades ago in China a new type of continuous kiln was invented. While the traditional continuous kilns (Hoffmann type) require a high investment the Chinese kilns are relatively easy to build and were copied in India a few years ago.
Vertical Shaft Kilns Lime shaft kilns are stationary vertical kilns where the limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating calcining and cooling zones.
vertical kiln - amberfortin. Vertical Shaft Brick Kiln (VSBK) Technology | VSBK-SCP Vertical Shaft Brick Kiln (VSBK) Technology The Vertical Shaft Brick Kiln (VSBK) is a clean green brick firing technology has evolved from the traditional up draught .
In a continuous kiln on the other hand the fire is always burning and bricks are being warmed fired and cooled simultaneously in different parts of the kiln. Examples of such kilns include Bull's trench kiln (BTK) Hoffmann Zig zag kilns Tunnel kiln and vertical shaft brick kiln (VSBK) (Heierli and Maithel 2008).
The Vertical Shaft Brick Kiln is a civil structure consisting of insulated vertical shafts in which bricks are fired. This is a continuous operation kiln capable of round-the-year operations. Through VSBK production can be easily scaled up or down to meet different levels of demand. Preliminary assessment indicates that unlike other brick kilns like …
FACTSHEETS ABOUT BRICK KILNS IN SOUTH AND SOUTH-EAST ASIA FIRE Vertical shaft brick kiln is a continuous moving ware kiln in which bricks are ˜red in a vertical shaft of rectangular/square cross-section. The height of the shaft is around 6 – 10 m and the cross-section of the shaft can range from 1.0 x 1.5 m to 1.75 x 3.75 m.
