<p>Bricks are fired in a clamp using gas burners burning, for example, butane and thereby avoiding the expense and wastage which results from firing with a conventional coke bed. The green bricks are built up from a concrete floor, with fire tunnels and associated flues formed in the clamp structure. The lower courses of green bricks are open-set but the remainder of the clamp is close-set. The sides and top of the clamp are covered by a casing structure.</p> |
