FURNACE FOR MANUFACTURING YELLOW PRUSSIATE OF POTASH.v
SPECIFICATION forming part of Letters Patent No. 544,580, dated August 13, 1895.`
' Application filed May 29, 1891. Serial No. 394,476. (No model.)
To @ZZ whom it may concern:
Be it known that I, SIEGMUND HALLA, a subject of theEmperor of Austria-Hungary, and a resident of Vienna, in the Empire of 5 Austria-Hungary, have invented certain new and useful Improvements in Furnaces for Manufacturing Yellow Prussiate of Potash, of which the following is a specification.
The ordinary reverberatory furnaces for manufacturing yellow prussiate of potash have numerous disadvantages, the chief of which are, first, contamination of the melted product by ash proceeding from the iiring; secondly, the loss of nitrogenous products and of potash by the draft from the melting-pan to the chimney; thirdly, the insufficient regulation of the draft; fourthly, the too free admission of air at the feeding-opening of the melting-pan, and, fifthly, the destruction of the fire-bridge by overheating. All these disadvantages are overcome by my improved furnace, which is shown in the accompanying drawings, in which- Figure lis a front View; Fig. 2, a side view; Fig. 3, a side sectional view taken on line A B, Fig. 4. Fig. 4 is a sectional plan through line XY of Fig. 5. Fig. 5 is a cross-section through line C D of Fig. 4. Fig. 6 is a cross` section through line E F of Fig. 4. Fig. 7 is 'a sectional plan showing the connections of the flues with the chimney.
G is the melting-plan; I-I, the furnace; I, the fireproof roof of the pan and the furnace; K, a sliding door for removing ash-dust; L, the firing-grate; M M, chambers for absorbing nitrogenous volatile products; N N, tightlyclosing doors for introducing and taking 'out absorbent materials z; O, a fan for drawing off the gases passing through the absorptionchambers; P, a slide for regulating the draft of the fan; Q, Figs. 2 and 4, a tube for conducting air into the absorption chambers and serving at the same time for cooling the fire-bridge; R, sliding door with working-hole d; S, flue for the gases from the melting-pan to the absorption-chambers; T, air-tight ringdoor; F, air-tight ash-pan door with regulator c; U, reservoir forevaporating potash lye; V, Figs. l and 4, opening for cleaning the fiue According to my present invention the automatic removal of ash-dust proceeding from the firing is effected by the aid of a suctionflue d, Figs. 3, 4, and 7, opening into the furnace H and connected with the chimney T2 55 by means of the subterranean flue d. This section-fine d can be made of brickwork or of earthenware or iron tubes. Theregulation and working of this suction-flue is effected by opening or closing the slide K more or less. 6o As soon as the slide K' is drawn up, the draft of the chimney draws the ash-dust collected in the fireplace above the grate at once into thechimney through the dues d and d.
Between the melting-pan G and the chimo 5 ney the absorption-chambers M M are arranged, which are composed of a series of trays, on which absorbents ,a z are placed. The gases and vapors passing off from the melting-pan to the chimney take their path 7o over these trays and yield to absorbents z .c what they contain of. potash or nitrogenous products. The absorbents a' z may consist of coke, pumice-stone, slag, or the like, and may be moistened with sulphuric acid forimproving their action. Air-tight doors N N are arranged for the insertion and removal of these absorbents, and the trays for the same maybe made of earthenware or iron. The proper regulation of the speed of the 8o gases passingoff is very important. For this purpose I arrange beneath the last of the aforesaid trays a fan O, which communicates through the flue O and subterranean flue O2 with the chimney. The slide P, arranged above the fan, regulates the admission of the gases tothe fan. The rotation of the fan O is edected by the draft of the chimney.
For the purpose of diminishing the quantity of air entering to the melting-pan during 9o the process, the door R has only a small working-hole a, through which the stirring of the materials in the pan is effected, and a separate door W is arranged, through which the materials for the melting-pan G are fed.
In the tire-bridge of the furnace atube Q is arranged. The air passingthrough this tube serves for cooling the fire-bridge and thereby diminishing its Wear and tear, and then for regulating the temperature in the absorptionroo chambers M M, as too great heat in these chambers would diminish the absorption power and generally inj uriously affect the entire process. The cover Q to this tube Q is closed as soon as the processis completed, and thus prevents the escape of valuable gases.
The method of using the apparatus is as follows: By means of the furnace H the pan G is heated to about 900o centigrade. During this operation the slide P is kept open` and the slide K is kept closed, except when the Iire is being stoked, in which case the slide P is 'closed and slide K is opened so as to vprevent any ash-dust from entering the melting space. As long as the slide P is open, the fan O is kept in motion by the draft from the chimney. As soon as the pan is suti ciently hot the necessary quantity ot potash is introduced into the same through the door R. When the potash is melted, the draft is reduced by closing the slide P so far as t0 leave an opening of only about one inch in width, and then the nitrogenous materialssuch as horn-shavings and cloth-clippingsareintroduced into the pan through the separat-e opening W. The mixture is stirred about by means of a tool introduced through the working-hole a in the door R,and the vapors evolved during this process are collected in the absorption-chambers IWI M.
sorption chamber, substantially as set forth.
2. In a furnace for making prussiate of potash, the combination of the fire-place, melting pan, and iue leading from the melting pan to the chimney and provided with absorption chambers, with a tube Q leading from the outer air to the absorption chambers, as and for the purposes set forth.
In testimony whereof I have aflxed my sig- 5o nature in presence ot two Witnesses.
