UNITED STATES PAT JOHN C. HANRAHAN, or Los ANGELES, CALIFORNIA..y
STEAM 301mm.
Application led February 3, 1922. Serial No. 533,874.
the provision of a boiler furnace in whichV the drums constituting the boiler are so associatedwith each other, and the water supplied and the steam discharged from the drums in such manner as to effect a duplex circulation of water within the boiler, thereby permitting of a wide fluctuation inthe water level without injury to the drums andl tubes constituting the boiler, and preventing the escape of water from the steam discharge or pulling over caused by` formation steam -pockets in the lboiler tubes.
It is also a purpose of my invention-to provide a boiler furnace in which the boiler drums are effectively supported and in a manner to-allow -of the necessary diaphragm expansion and contraction of the parts comprising the boiler and without the possibility of such parts being cracked or otherwise imaired. V .i p A further purpose yof my invention is the provision of a boiler furnace including perforated baffles associated with the boiler tubes so as to in no way restrict the draft area and yet completely dissipatek the un-V burnt combustible products and thereby'pro-- mote perfect combustion.
I will describe one form of boiler furnace embodying my invention and will thenpoint out the novel features thereof in claims.
In the accompanying drawings, Y
Fig. 1 isa view showing in section and perspective one form of boiler furnaceembodying my invention. Y
l Fig. 2 .is an enlarged fragmentary sectionalv view of two of the drums comprised in the boiler shown in Fig. 1 and the baffle and tube connection therein. n Y
, Fig. 3 is a view similar to Fig. 2 and taken at right angles to the latter.
Fig. 4 is an enlarged fragmentaryv sectional view .of one of the water legs comprised in the boiler furnace shown in Fig. 1.
Fig. 5 isa view showing inv side velevation the bottom or purifying drum of' the 'boiler furnace shown in Fig. 1.
particularly to Fig. 1, my invention, in its present embodiment comprises a suitable base 14 upon which is supported a furnace structure yincluding side walls 15 and 16 and an intermediate wall 17. Between the side walls and the intermediate wall and contact ing with the former are subsidiary walls 18 and 19. The walls 15 and 16 are provided on their vinner sides with shoulders 20 curved to accommodate boiler drums D and D horizontally arranged and provided with water legs L and L depending from the latter and positioned within suitable openings formed in the subsidiary walls 18 and'v19. In the present instance I have shown the water legs LjandvL sustained on tubular supporting columns 21 arrangedwithin the walls 18 and 19 andpfhaving their upper ends vconcave to accommodate the ,convex ends 22 of the water legs, all as clearly shownv iuF ig. 4. The lowerends of the water legs are providedfwithcollars 23 adapted to receive fthe upper ends ofthe Vcolumns 21, and to thereby provide a substantial connection` between the legs andcolumns.
lThe upper edge of the intermediate wall 17 is convex to accommodate a drum D2 which constitutes the purifier of the boiler, and superimposed upon the drum D2 is a second intermediate walll24 which is convened at its upper and lower edges to conform in the latter instance to the contour of the drum D2, and inthe former instance to a drum D3 disposed betweenbut above the drums D and D. 'A fifth drum D4 is arranged above the drum D3 and a third inten mediate wall 25 is interposed between the ment, the intermediate walls 17, 24, and`25V serve to collect and transfer heat to' the several drums arranged on/suc-h walls, and more particularly the purifying drum D2, thereby greatly assist-ing combustion and givinga `wide grate area. The furnace structure inclu-des a. cover` 28 conveXed at its medial portion and longitudinally to first drum and in a higher plane, tubes connecting the second drum tothe first drum, baie blocks upon the tubes against the drums and having perforations for the passage of heat, a third drum at the outer side of the other fire box and in the same plane as the second drum, tubes connecting the t-hird drum to the first drum, bale blocks upon the tubes and against the drums and having perforations for the passage of heat,v water legs extending downwardly from the second and third drums outside of the fire boxes, a second intermediate Wall extending upwardly from the first drum, a fourth drum resting upon the second intermediate wall7 tubesconneeting the fourth drum to the second and third drums, a fifth drum above the fourth drum, tubes connecting the fifth drum to the second and third drums, baile blocks upon the of tubes and having perforations for the passage of heat, and Walls outside of the fifth `and sixth sets of tubes, said walls terminating short of the fth drum for the passage of hea-t over the upper edges and a breec-hing over the'ifth drum into which the products of combustion discharge.
In testimony whereof I have signed my name to this specification.
JOHN C. HANRAHAN.
