O knihe

Excerpt from Tall Chimney Construction: A Practical Treatise on the Construction of Tall Chimney Shafts, Containing Details of Upwards of Eighty Existing Mill, Engine-House, Brick Works, Cement Works, and Other Chimneys in England, America and the Continent

A chimney Shaft, when in work, contains a tall column of heated air, which, being lighter than the outside atmosphere, is forced upward by a corresponding column of atmospheric air pressing into the entrance of the furnace thus a displacement of hot air is constantly being effected, and its place filled by normal air forcing itself through the furnace of the boiler, which air is in its turn heated and displaced. The column of atmospheric air and the column of rarefied air in the chimney are somewhat like a pair of. Scales, or the two ends of a lever of which the boiler is the fulcrum.
