Theheat around each cylinder is regulated by registers r and r, in the vertical pipes u and u. Thepart a 6 c of the cylinders which is more immediately exposed to the action of the fire is coveredwith a luting of broken tiles and clay. The maximum of temperature is thus found at the top ofthe cylinders, favouring greatly the progress of the
