This invention relates to boilers and in particular to an improved seini-instantane ous vaporizing tubular boiler, characterized by the newarrangement oit its tubular system. The boiler or the present invention is intended'to develop great power with a very small. volume, especially when applied to a motor car, -tor example. It istheretore essential for the boiler to have a large heating surface compared with its volume. This'result is attained, as will be explained later, by a special arrangement ott tubes. Moreover, the tubes are arranged in such amanner that the gases of combustion :from the lire are retained as long` as possible in the tubular system, so that they may be deprived oit' their heat, while allowing the gases a suicient section ot passage to enable combustion to proceed in normal conditions. Thus a maximum utilization oi the heat produced in the furnace is attained.
A form of construction of the boiler is shown in the accompanying drawings.
Fig. 1 is a liront elevation oit the device, partly in section,
Fig. 2 is a section on the line 2 2 in Fig. 1;
Fig. 3 is a side elevation, partly in section, showing` the arrangement of the tubular system comprising tubular elements each or' which consists oit' tour tubes marked I, II, III and IV.
Fig. l is a view, in elevation, of a -fragment of an element showing tube I unobstructed in view by II, III or IV.
Fig. 5 shows the arrangement of the tour tubes of an element, seen in plan; and
Figs. 6, 7, 8, 9 are plans of tubes Nos. IV, III, II, and. I respectively, shown separated one from the other.
The tubular system of the boiler is ar ranged as follows to realize the conditions ot working described later.
(l.) To utilize the greatestnumber of tubes possible in the space available, all the tubes lie in adjacent vertical planes and are stepped in height, at equal distances from each other. When viewed in plan (Fig. 2) the tubes ot the system appear rectilinear and contiguous 'from end to end having between them only the necessary play for mounting, the ends appearing looped. They all appear viewed in elevation (Fig. l) as coiled with uniform inclination to rocluce :atilii'al circulation ot' the steam@ lilas loops connecting the ends ot the straight parts ot the tubes have the saine inclination as the straight parts thereof. Owing to this the steam formed in the bottom parts of the boiler tends to acquire a uniformly accelerated ascensional movement.
(2) The tubes are arranged in groups oi' tour expanded at their ents in bones 5, 5 inclined at 15 with respect to a plane pass- :ing through the axes of the four tubes (see Figs. 1 and 2).
Ilach group or element of the system comprises four tubes and two junction boxes 5 and 5 (Fig. 1) the latter being connected by means ci conical'nozzles and the tubes 2 and 4t with the steam chest 1 and the feed water collector 3 respectively. Thus each element can be detached from theboiler by unscrewing the union pieces 17 and 17. Thus a group or element ot the system can be replaced with remarkable ease. Threaded plugs 18 and 18 positioned opposite the ends of h tube vpermit expansion of the ends and cleaning ot the interior. i
To allow the combustion gases togive up their heat as completely as possible and also leave them a su'liicient passage to find their way to the exit or chimney, adjacent tubes are inclined alternatively in oppositedirections to each other, in such a manner that although all the tubes appear in plan to be longitudinally contiguous (Fig. 2) theapparently contiguous parts of any two adjacent tubes have really only one point of contact; their arrangement is also such that the gases which ascend vertically in the conduits or' passages between the two consecutive tubes No. III always meet a tube No. I around Awhich they have to pass in the free spaces lett above. Increase of incline :facilitates e circulation ot the combustion gases, owing to increase of thev aforementioned spaces. VDecrease of this incline evidently has the opposite etiect;l for with no inclination the'tubes would be contiguous throughout their length and the draught be completely suppressed.
Each element ot the system comprises lour similar tubes I, II, III, IV (Figs. 6 to 9). These tubes are alike in pairs. tube I being similar to tube IV and tube II to tube III. The extremities alone dii'er at the point of connection with the botes. rllge loops of tubes I and IV are completely allient with respect to the plane of the tube Licensee and those of tubes ll :ind lll ere partially so, in such n. Wny that when the tubes l, llt, lll and lV are brought close alongside one another fill the loops will orerlnp erich other very exactly :ind be concentric.
ln the mounting?,` ot the tubes on their boxes, corresponding portions oi tubes and lll, and oi tubes ll and lll lie in two diilerent planes spaced eport horizontally by one thickness of tube ns shown in Fig. 2, the tn'o horizontal planes in question being distant to an extent equal to` heli the pitch olf the coil or spirnl so ns to obtnin the points of eontnct in the iniddle regions of the tubes.
Moreover the lirst and lest branches oli the tubes lll, lV, ere slightly modified so that the loops oit these tubes, it mounting, will be placed exactly under end olinost in contact with the corresponding loogs oli tubes l, ll. rlhe tour tubes thus tor-ined nre then brought close tooether in the order l, ll, illlll/T until ell their loops :re concentric end their ends n nnnlly eionnded in their box s, so :is to .ii nn element.
he outside dinineter el" the loons should be equal to four tiines t le dinineter of o. tube plus n certain ploy witch nnry be eqnzrl to one tenth the dieineter ot the tube.
vBriefly, the invention consists in n seiniinstentaneons vsporizing boiler, for nll npiplicntions, `with n snnill yolunie of Water, characterized by the orennizetion ot l tubular lsysteni formed oit eleinents arranged on the one hond to (erelop greet power with n Very sniell volume end, on the other hand, to nllow ninXii-nnrn ntilix/intion ot lient produced in the tnrnncc, retaining,` the grises ot combustion :is lone; ns possible .in 'the tubular system und ellon'ing then-x also n si'itlieient section ot' passage lor combustion to tolte place in nornnil comlitions.
