Abstract
Clay pipes and the like (3) are fired in a kiln (1) through which they are conveyed by a pusher conveyer (2, 4) as individual articles, instead of being carried on cars or in containers. In the main firing zone of the kiln the pipes (3) roll along a surface (6) to maintain roundness and ensure uniform heating. In the preheating zone of the kiln the pipes are carried by carriers (5) of the conveyer without rotating. The pipes may also be carried without rotating in the final cooling zone of the kiln.
