As shown in the drawings, the tube banks 00 of the respective boilers are disposed in parallel relation and the water tubes C of said banks extend parallel to the side walls'D of the setting. The drums are disposed transversely of the boiler in parallel relation to the front wall of the setting, and the tube banks are disposed at the rear A lgreater quantity of fuel can be burned, due to side of the combustion chamber in opposed relation to the front wall F of the setting;Thef
arch H is arranged between the tube banks, in close proximity to the drums A, and consequently,
causes the gases in the upper portion of thecom-l bustion chamber to be deflected laterally into the upper portions of the tube banks located at the opposite sides of said arch. Said arch is pro-V vided with means or is so constructed as to effec-v tively prevent the products of combustion from escaping from the combustion chamber E around the inner ends of the drums A, and also prevent theproducts of combustion from injuriously afiectingl the overhead structure that sustains or supports theinner ends of the dums A.
, In the apparatus herein illustrated the outer ends of the elevated drums A are supported by the side walls D of the setting or by girders or other suitable supports built into said side walls,
and the inner ends of said drums A are sustained by anoverhead supporting structure that comprises horizontallyr-disposed membersl I that extend longitudinally of the apparatus from the front to the rear of same, and hangars 2 which suspend the members l from horizontally-disposed I-beams 3, which, in turn, are supported by uprights 4 arranged adjacent the front and rear walls of the setting. Obviously, the inner ends ofthe drums A may be supported in any other preferred or suitable way.
The arch H is'herein villustrated as being composed of groups of refractory blocks or tile 5 combined with flanged hangars 6 that are car-V riedby a horizontally-disposed I-beam 1 or other suitable means which is suspended from the members I of the overhead drum supporting structure, previously described, said blocks or tile 5 being of such cross-sectional shape that they co-act with each other to produce an arch H atV the top of the combustion chamber, which causes the gases in the central portion of the combustion chamber to be thrown to either side of the arch, intof the water tubes of the respective units. Shallow vertical walls 8 made of re'brijck, are erected on the archfH so as to surround or partially surround the inner end portions of the drums A and prevent the gases from escaping from the combustion chamber E at the dividing line of the two units, or having an injurious eifect on the4 overhead structure that supports the inner ends ofthe ,drums,A. The metallic parts of the arch H areprotected from excessive heat by the arch tile 5. When my invention is applied to two Sterling type boilers, as herein illustrated, the baflies ofthe front tube banks of the respective boilers are joined together in such Va way, as,
A steam generating apparatus ofthe 'construc-Y tion above described, in comparison with a conventional battery boiler of equal heating area and-of equal steam disengaging area,V has vthe followingadvantages:'v i Y (1) It has a single combustion chamber or space common to the tubes and the drums of both boilers, in which fuel can be burned more effectively than in two separate and distinct small combustion chambers;
V(2) It has a combustion chamber in which a the fact that the elimination of the party wall of the conventional battery boiler and throwing the two combustion chambers into a single combustion chamber, adds considerably to the volume of the combustion chamber;
(3) It. has a grate area or burner space which is much larger than the grate area or burner space of the conventional battery boiler, because the space formerly takenA up by a party wall is now available for additional grates or for oil, gas or other burners; and y Y (4) It conserves or more effectively utilizes the heat obtainedfrom the burning fuel, as there is no "party wall or other large mass of refractory material at Vthe dividingv line of the two boilers that absorbs considerable heat, especial-j My improved apparatus has the additional ad;
vantage that a conventional battery of boilers can be converted into this improved Vfurnace by simply removing the common battery wall and replacing it withthe suspended arch arrangement, without moving the boilers or the outer walls of the combustion chamber. A;4 -V Y Having thus.y described my invention, what I claim as new and desirefto secure by LettersPatent is: i
1. A steam generating apparatus composed of a plurality of small boilers arranged side by side, a setting comprising a front wall and side walls, each of said small boilers comprising tubes that extend parallel to the side walls of the setting and drums attached to said tubes and disposed transversely of the boiler in parallel relation to the front wall of the setting, the tube banks of the respective boilers extending parallel to each other and being disposed at the' rear side of the combustion chamber in opposed relation to the front wall of the setting, and a suspended. arch structure arranged between the tube banksl of adjacent boilers so as to form part of the roof of the combustion chamberand extending from the front wall to the rear wall of the seti sides of said arch structure. l
