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
In contrast, modern brick kilns like the VSBK and Hoffman kiln produce fewer emissions and consume less energy, making them more environmentally friendly. The hybrid Hoffman kiln is a good option for large investors, while the vertical shaft brick kiln is a good choice for smaller investors considering energy efficiency (Darain et al. 2016).
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. The VSBK originated in China in the 1970's.
