H.E.R.O - Tunnel Kiln for Heavy Clay Masonry Blocks

In a tunnel kiln, which is a horizontal moving ware kiln, bricks to be fired are passed on cars through a long horizontal tunnel. The firing zone remains stationary near the centre of the tunnel, while the bricks and air move in counter-current paths. Cold air is drawn from the car exit end of the kiln, cooling the fired bricks.
