PANEL BOILER non Low-PRnssunn-srnmvr HEATING.
Application filed May 31, 1922, Serial No. 564,713, and in France June 18, 1921.
of the said conduits together with connecting apertures disposed upon said transverse canals in order to connect the plates together or to outer steam or Water conduits.
A plate of this kind may be considered as being composed of a set of parallel tubes connected together by intermediate ribs and by transverse main tubes, the whole being cast in one piece.
According to my invention, it is feasible to construct boilers of a considerable capacity comprising the drum and elements of small size and light Weight, which have great strength and are constructed with facility, whereas the known sectional boilers are composed, for the large sizes, of heavy and bulky pieces which offer a great risk of breakage and are difficult to manufacture.
In the boilers according to this invention, plates of uniform construction and varying only in number, are employed for the con struction of boilers whose heating surface and resulting capacity may differ within wide limits.
The accompanying drawing shows by way of example in lengthwise, transverse and horizontal section various constructional forms of boilers according to the invention, wherein:
Figs. 1, 2 and 3 relate to a boiler having a furnace and a main body of brickwork.
Figs. 4, 5 and 6 relate to a boiler without brickwork.

Fig. 2 is a partial vertical section on th line 2 2, Fig. 1.

Fig. 5 shows to the left a half vertical place of several plates,
sectionon the line 5-4), Fig. and to the right a half-verticalsection on the line 55 ofthe same figure.
Fig. 6 is a half plan View in section on the line ('56, Fig. i.
In Figs. 1, 2 and 3, the boiler therein represented has been constructed in order to provide forthe maximum facility of manu facture at a minimum cost. It comprises two groups whereof each is composed of a. cast iron drum 1 and two sets of four panels 2 and 8 connected together and connnunieating with the drum at the front by the necks 4 and in the rear by the tubes 5. Each pair of panels 2 and 3 is independent of the others and communicatesjiinlividmrlly with the drum; the water circulation takes place in one plane and without a complicated path; the "water descends directly from the drum through the rear tubes .5 and rises through the front tubes l after traversing the panels 2 and The circulation of the 7 hot gases will preferably take place in contrary direction to the water circulation, but this is not essential. It is preferable to dispose a steam separator (5 in the drum 1 at the steam outlet.
The drum 1 is suspended from the sup- I ports 7 by the straps 8 as carried out in certain water tube boilers, and the tube elements are suspended directly from the drum without any other means of support, so that as all parts of the boiler are enabled to expand freely Whereby'any stresses tending to cause leakage or breaking will be obviated. Should the capacity of the drum be insuflicient, it will be an easy matter to substitute for the steam header 9 a supplementary steam chamber. On the other hand, in the case of hot water boilers, the diameter of the drums 1 may be very small, and each of these may support a single tubular plate in (ill In Figs. 5 and 6. the construction of the boiler difiers from that of Figs. 1 to 3. In the first place, the upper part is no longer composed of cylinders of cast iron or plate iron disposed parallel to each other and lengthwise of the boiler, but is formed of the cast iron sections 10 analogous to the ones employed in sectional boilers. The said sections are connected together by two apertures 21 of large diameter so as to facilitate the circulation of water and. steam therethrough. They have a suitable moulded shape at the edges and at the ribs for strengthening the bottom. The. said sections are disposed upon an iron trains of double T-iron 22.
The number ot panels 2 and 3 will vary according to the requisite heating surface, and the sections 10 may be made in any desired size. for a given number of pairs of panels and the desired heating surface. The panels :2 and 3 are suspended from a front section it) by necks l, and at the rear are supported by the conduit 13.
In the second place, the brickwork can be eliminated in this type, and the sides of the boiler are constituted by tubular panels ll connected at the top with each section 10, and at the bottom with a main side conduit 12; the latter is connected with a main rear conduit 13 which communicates with the panels 3 and the water descent tubes of the sections 10. The panels 11 are all of uniform construction and can be moulded with facility. It necessary, each one of the said panels can be replaced without interlering with the others, even should the boiler form part of a battery. In this case, the upper connect-ion ot' the panel ll which requires to be replaced is dismounted from the outside, whilst the lower connection is dismounted from the inside of the ash pit. The front plate is "faced with lirebrick on the inside corresponding to the furnace portion. Certain portions of the rear end may also be lined with brick on the inside, but a heat insulating lining will suffice as a general rule. The top and sides of the boiler are provided with a heat insulatingcovering as in the sectional boilers.
By varying the dimensions of the top sectiolls and the number of pairs of panels 2 and ii. any desired size of boiler can be obtained; the panels 2, 3 and i1 will remain the same tor all sizes, and only the top sections and a few flat pieces will be difl'crent.
The boiler shown in l igs. 1, Q and 3 may also be constructed with a top analogous to the one shown in Figs. 4, 5 and 6. A combined construction may also be used wherein the various cast iron elements or drums are replaced by a single cylindrical drum or a plurality ol parallel cylindrical drums constructed of iron or steel plate, whilst the tubular portion is composed, as before, of cast iron panels. The drum or drums might also be disposed transversely to the plane of the heating panels "A, 3 it instead of parallel to the latter. inspection and cleaning of the panels l'orming the tube sets is much im'ilitated by the apertures provided tor the purpose. as :-lHJ\\'Il in the drawings. The grate has a sullicient size to dispense with very frequent cleaning, and means may be readily employed to ail'ord a larger size for the. grate should this be desired. The furnace is disposed so that a (@l'ttllll thickness of combustible can be led in, when coke or anthracite are used.
Should it be necessary to replace one ol' the panels l'or any rcasom this may he very readily carried out without interfering with the adjacent, pairs of panels or the briclo work. The :aid boilers are very well adapted for installation in batteries. The arraiug'cment ol' the furnace provides tor the use oi mechanically OPt'i'tltQll grates, and this may be :ulvantageous in large plants. In the boilers herein represented, all the joints are visible and quite accessible.
.l claim:
1. A boiler comprising a drum, and a plurality oi pairs oli vertical water heating panels disposed below said drum and comnnlnicating therewith. each panel consisting of a set of parallel tubes and tubes transversely thereof cast in one piece. the panels ol' each pair being alined at the trout. and rear of the boiler l'tfildttftlYttbY and being communicatively connected. the l'ront panels being arranger l with the parallel tubes thereof inclined and the rear panels being arranged with the. parallel tubes thereol' vertical. substantially as specilied.
