JBrooman’s Improvements in Smoke-consuming Furnaces. of a blowing apparatus as means of increasing their draught, of increasing their pressure, of producing hydrogens by the decomposition of this steam or water, and of facilitating the leading of the gases from one point to another and of directing them with a certain pressure out of this apparatus; 3rdly, the hermetic and almost continuous mode of charging 5 owing to the reduced volume of the charge; Ithly, the complete enrichment of the gases developed in all the parts of the apparatus by causing the gases to return into the apparatus which has generated them, in order that they may not issue therefrom until they have been enriched therein through a layer of incandescent fuel; 5thly, the 10 simple and economical mode of heating the new air for burning the combustible gases in a special combustion chamber; and, Gthly, a com¬ bustion chamber, one of the sides or walls of which is formed with holes by which the burnt gases pass as through a sieve in order to enter the apparatus to be heated. 15 I proceed to describe a furnace or apparatus constructed according to this Invention. Boxes for charging the fuel slide on perforated plates, and the fuel falls down tubes upon the bars of the first fire-place. These bars are preferably arranged stepwise or as shelves. This fire-place has hollow fire-bridges formed with small holes. The fuel is lighted on 20 the bars of the first place, and its distillation effected. The greater part of the gaseous products of this distillation passes over the fire¬ bridges, impinges against the under side of fresh air tubes hereafter referred to, and passes down vertical channels leading to arched openings or passages; these openings or passages conduct the gaseous products 25 into the incandescent fuel on the grate bars of a second fire-place below the first, so that the products become enriched. The other part of the pro¬ ducts passes direct to the second fire-place. Superheated steam supplied to the hollow fire-bridges escapes by the small holes therein, and favors the passage of the gaseous products down the vertical channels from the 30 first to the second fire-place in which this dry steam is decomposed, and in which the gases and vapors become saturated with carbon in order to supply to the combustion chamber hereafter referred to only very combustible gases. Eresh air for burning the gases in the combustion chamber is forced or drawn through the fresh air pipes before mentioned. 35 These pipes are at the upper part of the apparatus, and the air admitted by them passes down a vertical space in one of the walls. The air is thus heated and afterwards mixes with the gases at the lower part of
