What is vertical shaft kiln technology? Vertical shaft brick kiln (VSBK) is a continuous, updraft, moving ware kiln in which the fire remains stationary while there is counter current heat exchange between air (moving upward) and bricks (moving downward). The VSBK technology has evolved from the. traditional up-draught kilns in rural China.
