This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1897 Excerpt: ... cone called the bosh, and a bottom cylindrical portion or hearth. These portions may be separated by distinct lines of demarcation, or they may curve gradually one into the other. Small blast-furnaces may be of the same diameter all the way down, or they may taper gradually from top to bottom. The ratio of height to greatest diameter may vary very much, but in modern furnaces is usually about 3-5 or 4:1, varying down to about 3:1 and up to 6:1 in very exceptional cases. The charge is introduced at the top, which is now almost always provided with some form of charging apparatus by which the gases can be drawn off, since these are combustible and are therefore of value. Air is blown in by a series of tuyeres just at the top of the hearth, leaving space below for the accumulation of the molten slag and metal which are tapped out periodically from tap-holes in the hearth, one at a higher level for the slag and another at a lower level for the metal. Tho air is supplied from the blowing engines or fans by a blastmain which passes round the furnace. The chemical action which takes place in the blast-furnace is in the main simple. The air coming in contact with the fuel at a high temperature, its oxygen is at once converted into carbon monoxide, and if by chance any carbon dioxide should be formed it would be instantly reduced, so that the gas as it ascends will consist essentially of a mixture of carbon monoxide and nitrogen, having exactly the composition of simple producer-gas. In addition there will be a small quantity of hydrogen from the moisture contained in the air. These gases will be powerfully reducing, and therefore the atmosphere in a blast-furnace will be always reducing, and the oxide of iron or other metal charged into the furnace will be reduced...
