    2 A.D. 1854.—N° 604. Provisional Specification. Wright's Impts. in the Construction of Furnaces for Consuming Smoke. *, - — ■ -- —-- .. . ■ - - ..i - —■ ■ lump being about half the length of those fire bars, over which it is placed with its end flush with the ends of said bars, and I employ such said lump as a transmittor of heat; that is to say, the heat which radiates from the fire which is upon the fire bars beneath will have the effect of making said lump red hot, or even a white heat if allowed; but as this would cause fusion of the metal I 5 prevent it from attaining so high a temperature by allowing a current of cold air to pass through such said hollow lump; thus it will be seen that by main¬ taining a very high temperature at this part of the furnace, more perfect com¬ bustion is insured, and the smoke and combustible gases as they pass such part are thereby more effectually consumed before they enter the chimney by reason of 10 the upper part or crown of the furnace being of the same temperature as the fire which is upon the bars, whereas in furnaces as heretofore constructed, and more especially the furnaces of steam boilers, the metal of which the boiler is made not being capable of attaining even a red heat (solong as there is water therein), inflammability of the smoke and gaseous and other vapours cannot therefore 15 possibly take place, and the smoke therefore passes olf unconsumed or only partially so; and this Invention applies also to the furnaces used by bakers, and to every description of furnace in which the smoke is required to be consumed.
