VASSILI P. ORLOFF, OF MOSCOW, RUSSIA.

STEAM-BOILER.

SPECIFICATION forming part of Letters Patent No. 332,357, dated December 15, 1885.

Application filed June 19, 1585.

To all whom, it may concern:

Beit known that I, VAssILI P. ORLOEE, a subject of the Czar of Russia, residing at MoscoW,Russia,haveinvented certain new and useful Improvements in Hot -Vater and Steam Boilers; and I do hereby declare the following to be a full, clear,and exact description ofthe invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, and to letters or figures of reference marked thereomwhich form apart ofthis specication.

The object of this invention is to increase the heating-surfaces of boilers for heating water or generating steam; audit consists, essentially, in substituting for the usual cylindrical lues or tubes a series of heating u'es or passages, either of annular or rectilinear shapein cross'section, formed by a series of partitions arranged in the water-space of the heater or generator.

The invention further consists in the arrangement of the heatingchambers relatively to the source of heat and the escape duct or chimney to more eifectually utilize the heatin heating water or in generating steam, substantially as hereinafter fully described and shown in the accompanying drawings, in which- Figures 1 and 2 are vertical transverse sections of a water-heater, taken, respectively, on lines 1 2 and 3 4 of Figs. 3 and 4, which latter gures are horizontal sections taken on lines 5 6 and 7 8 of Figs. 1 and 2, the condenser in Fig. 4 being shown in plan view. Figs. 5 and 7 are vertical transverse sections of a vertical steam-boiler, taken, respectively, on lines 9 10 13 14 of Figs. 6 and 8, the latter two figures being horizontal sections taken, respectively, on lines 11 12 15 16 of Figs. 5 and 7. Fig. 9 is a vertical longitudinal section of a horizontal steam-boiler on line 17 18 of Fig. 10. Fig. 10 is a vertical transverse section thereof taken on line 19 20 of Fig. 9.

Ihave hereinbefore stated that instead ofconstructing the heater or boiler with fretubes for the circulation of the heat and products of combustion, Iprovde a series of heating dues or passages formed by properly partitioning the water-space. These dues may be arranged Serial No.169,249. (No model.)

in various ways without departing from the nature of my invention. For instance, in the vertical boiler shown in Figs. 5, 6, 7, and 8. and the horizontal boiler shown in Figs. 9 and 10, I have shown these heating-fines extending vertically through the water-space; but it is obvious that, especially in the boiler shownin Figs. 9 and 10, they may be arranged in horizontal planes. In Figs. 1 and 3, on the other hand, I have shown the tubes arranged in the form of vertical cylindrical passages, and in Figs. 2 and 4 I have shown the ues as diverging from one side of the heater. I have given these examples of the different ways of arranging the iiues to show that said arrangements may be varied in a great many ways without necessarily departing from the nature of my invention.

Figs. 1 to 4, inclusive, showa water-heater, A, in which the heating-surfaces are formed by a series of annular or cylindrical lues, a, arranged between the transverse partitions b c and d e, Fig. 1, around and concentric with a central draft-tube, A', that communicates with the furnace B. As shown in Fig. 3, the

double walls that form the heating-fines c do not extend entirely around the central ue, A', of the heater, a'space, A2, being left,whicl1 is divided by partitions f g h, that extend alternately from the extremity or end of one of the fiues a on one side to the extremity of another flue on the opposite side of the central ue, A2. By means of this arrangement the heat and products ofl combustion passing into A from B are conducted, for instance, first through' three of the chambers, as shown at 1a 2a 3, by partition f, thence into the chamber formed by partitions f g, thence through iiues 4 5 into the chamber formed by partitions g h, and through fiues 6"L into the draft Hue or chimney t'. The heater is provided with a tubular grate, -D, that communicates with the Water-space of the said heater for obvious purposes.

C is the ash-pit, K K gage or draw off cocks, and a the steam escape pipe. The heater may be or is provided with the usual safety and other appliances, Z. Fig. 2 indicates a thermometer, and m an air valve or cock. The steam generated in the heater may be al- [ILD lowed 4to escape into the atmosphere through pipe a; but it is obvious that there would be a waste of heat,which I utilize in the heating of the feed-water by conducting the steam through a coil of pipe, O, arranged in a feedtank, P. The steam passing through the coil is condensed by giving up its heat to the surrounding water, the products of condensation (distilled water) escaping from the coil at r. The feed-water is admitted to the feed-tank P through pipe o, that is provided with a valve or stop-cock, p, to the stem of which is connected a lever carrying a float, q, whereby said valve or cock is automatically controlled, as is well understood. The heated feed-water is admitted to the boiler by a pipe, s, that is bifurcated, as at s s, to produce a more uniform circulation of the water in the heater.

In Figs. 5 and 6 I have shown the application ofthe heating-dues to a Vertical steam boiler or generator, or said boiler may serve as a water-heater. The heat and products of combustion pass from the furnace B through the vertical flues a, thence downwardly through a flue, a, and from the latter upwardly through a iiue, a2, formed by the outer shell of the boiler A and the water-space, and from thence said products of combustion pass to the chimney c. In these figures n also indicafes the steam-pipe and s the feed-pipe.

The construction shown in Figs. 7 and 8 is materially simplified, the products of combustion. passing directly from the chambers a to the chimney i, and n is the steam-pipe and s the feed-pipe. i

In Figs. 9 and l() I have shown ahorizontal steam boiler or generator,in which a indicates the vertically arranged heating'flues through which the products of combustion from the furnace B pass to the end of the boiler, thence downward to and through a flue, c, and through vertical iiues w, Fig. 10, to the chim ney i. Said flues U and w, nearly surrounding the boiler, are formed in the masonry work,as shown, and it is. obvious that, instead of arranging the dues a vertically,they may be arranged horizontally within the water-space. The number of these heating flues or passages for the heat and products of combustion, their relative arrangement, and dimensions may be varied and must depend in a measure upon the form of boiler employed and on thedimensions of the latter. These boilers are also provided with the usual safety and other ap.- pliances-such as try-cocks, pressure-indicator, level -indicator, safety-valve, blow-off cocks, and appliances for cleaning the flues and the boiler-.which are too well known and I have deemed unnecessary to illustrate the same in the drawings. Finally, both the water heaters and boilers shown may be surrounded by or inclosed in the usual jackets of wood or other substance that is a non-conductor of heat, to prevent loss of heat by radiation.

In a steam-boiler or water-heater, the combination, with the outer shell and the furnace located therein, of partitions arranged to subdivide the interior of the shell into a series of contracted or narrow continuous passages and form an axial draft-Hue, AQ for the circulation of the water and the products of combustion, the former enveloping `.or surrounding the latter and the furnace, said passages constituting independent circuits having their Ainitials connected with the feed-water pipe and axial draft-fine, respectively, and their terminals with a discharge-pipe and chimney, respectively,substantially as and for the purpose specified,

In testimony whereof I affixmy signatureV in presence'of two witnesses.
