FREDERICKW. KRONENBERG, OF PHILADELPHIA, PENNSYLVANIA.
DOWNFLOW STEAM GENERATOR.
Application filed A ril 15, 1922. Serial No. 552 854.
My invention relates to a new and useful improvement in downflow steam generators, and has for its object to so construct and combine a horizontal header with the lower sets of tubes of such a generator to permit the tree circulation and equalization of the water at the lowest point whereby the tubes and other parts of the generator subjected to the greatest heat of the furnace vill be protected against burning or other 1n ury,
A further object of the invention is-to so construct this horizontal header that it will provide for the receptionoi both the downiiow tubes and the upflow tubes and form a horizontal chamber the full width of the bank of tubes oi a capacity to carry sufiicient water for readily equalizing the water in all the tubes leading thereto or connected therewith.
Vith these ends in view, this invention constand how to make and use the same, I will describe its construction in detail referring by numerals to the accompanying drawings forming a part of this application, in Wh1ch:-
Fig. 1, 1s a vertical section or portion of a steam generator having my improvements embodied therein.
Fig. 2, is a front view of the header.
Fig. 3, is a plan view thereof.
Fig. 4, is an enlarged tragmental view of a portion of the header.
Fig. 5, is a section at the line 55 of F g. i.
Fig. 6, is a section at the line 6-6 of Fig. l.
In carrying out my invention as here embodied, 1 represents the setting of a boiler in which is mounted the drum 2 and from the lower portion of one end of the drum downtake tubes 3 lead (but one of said tubes being here shown), and these tubes are connected by a coupler 4 to the first series of downflow tubes 5 which are in turn connected with the second set of downtlow tubes 6 and these in turn are connected with the bottom downflow tubes 7.
8 represents the horizontal header which is cast in one piece and has a chamber 9 formed therein throughout the length thereof. Formed with this horizontal header are a number of boxes 10, the interior space of each box beingin opencommunication with the chamber 9.
Eaclroit the boxes 10 has formed therein an opening 11 for the reception of the lowest end of one of the downflow tubes 7 and also an opening 12 for a suitable handhold plate, here not shown. In the header beneath each box are formed two openings 1 3 for suitable handhold plates and directly opposite these openings are corresponding openings 1% for the reception of the lowest ends of the upflow tubes 15, the latter being expanded or otherwise secured in the header and extending on an incline rearward and upward and in the furnace 16 and connected by the couplers 17 to the uptake tube 18 leading to the coupler 19, the latter being connected by the nipple or short tube 20 with the drum 2 above the water level thereof.
21 is a drain formed with the header and may have connected therewith any suitable control valve.
In practice when my improved header is combined with a steam generator of the character described, the water and steam pressure in all of the tubes is equalized since the header forms an open free communication between the lowest ends of the tubes while the drum 2 forms an open free communication between the upper ends thereof, thus preventing any unequal action throughout the system and facilitating the circulation of the water down- }vard through the header and upward thererom.
I prefer to place a bafile 22 between the series of tubes 7 and 15 so that while exposing the tubes 15 to the direct action of the fire the tubes 7 will be less exposed thereto, thus intensifying the steaming capacity of the tubes 15 and as they are inclined upward from the header, which latter is the lowest point in the system the water will be forced to flow upward from the header through the tubes 15 at high speed.
By providing free communication between the tubes through the header a generator constructed in accordance with my improvement is especially adapted for marine work since the roll of a vessel will not displace the water within any of the tubes and therefore not expose said tubes to undue temperatures.
In order that the proper direction may be givento the products of combustion I provide the baflies 22 and 24: but of course any number of "b a ffles may be used and so 1 placed as to 'p'rodu'cethe desired results.
Of course I do not Wish to be limited to the @Xact i set eetumt e es her in-shew as these may be varied Within the limits of the appended claims Without departing from;
the spirit of my invention; I
Having thus fully describeum invention, What I claim as new and useful is 1-. FIii'adoWn-floW steam generaton aheaderj'coinpris'ing a longitudinally eiten'ding body ha'vinga chamber extending throughout 1ts entire length, a series of spaced outflow openingsthrough a side wallofsaldbod'y *arranged in paifr's for enmcun upflow "tubes with said chaniber, and ase'rie's of boxes corofoutflo'iv' openings superposed on said body, each box "having anop'ening for connection with adownflowtiibean'd opening into said chamber the space :betureen' the; two openings ofthe underlyingpairbf outflow openings, the top wa'llof each outflow opening beingclo'sely adjacent the top wall of 'saidbody,
whereby communication between adjacent boxes is baflied. .2. In combination with a downfiow steam generator havingga drunya header c0mprising a 'longitudinaily extending body having a chamber extending throughout its entire x enst a seri ee sewed e-w w openings through a side Wall of saidbody arrangedin pairs. for connecting upfiow tubes with said chamber, and a series of boxes corresponding in nuinbe'r to the number of pairs of outflow and a series-of upflowftubes"communicating with header ehamben-and said drum.
fln testirnoiiy whereof, I have hereunto "affiiied my signature.
