AUNITED STATES FRANK J'. LOGI-IEN, 0F CHICAGO, ILLINOIS.
BAFFLE PLATE FOR BOILER FLUES.
Application led September 11, 1925. Serial No. 55,644.
This invention relates tol improvements in battle plates adapted tobe removably 1inserted in the flues of boilers for interrupting the flow of hot gases therethrough and for distributing the gases in the flue so that all of the available heat units will be distributed throughout the heating surfaces of the fines thereby increasing the heating efficiency of the boiler with ainaterial reduction in fuel consumption.
It has been found that as the heated gases pass through the flue, and especially in oil burning furnaces and coal burning boilers that have been converted into oil burning boilers, the heating units in their passage through the flue do not all contact with the heating surfaces with the result that a great amount of heat is lost and passes out of the stack.
The heated gases have a free passage through the flue and only some of them hug some of the surfaces of the fiues while other portions of the liue surfaces are not contacted by the heated gases.
It is one of the objects of the present 1nvention to provide improved baffles which are separate from and independent ofthe flues and are adapted to be inserted into the fines to interrupt the flow of the heated gases therein and to cause the gases to flow in a tortuous passage so that all of the surfaces of the flues will be contactedby the hot gases and thereby utilize all of the heat units in the gases and prevent them from escaping from the flue.
A further object is to proyide improved baffles of this character which may be readily inserted into the flues of boilers now on the market without in any manner altering the construction of such boilers and which will effectively break up the gases and distribute them throughout the entire area of the flue and at the same time the bafties may be readily removed from the flue.
A further object is to provide improved baffles of this character which will provide i minimum amount of contacting surface vith the wall of the flue into which they are inserted.
To the attainment of these ends and the accomplishment of other new and useful objects as will appear the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts as hereinafter more fully described and claimed and as shown in the accompanying drawings illustrating the invention and in which,
Figure 1, is a diagrammatic view partly in elevation, partly in section, and partly broken away, of a round form of boiler having baiiles constructed in accordance with the principles of this invention arranged in the flues.
Figure 2, is an enlarged sectional view of a portion of the boiler illustrated in Figure 1 and one of the fines, with these improved baiiies in position therein.
Figure 3, is a detail perspective view of one of the baffles.
Figure 4, is a detail perspective view of another of the baffles.
Referring more particularly to the drawings, the numeral 10 designates generally a boiler having sections 11, 12, 13, and 14, superposed and secured together in any suitable manner.
Between the sections 11 and 12 is a flue 15 Y A similar flue 18 is arranged between the v sections 12 and 13 and a flue 19 passes through the section 13 and communicates with the iiue 18 and also with a similar flue 2O between the sections 13 and 14, and the Vues 16, 17 and 19 are so arranged that they will be outV of registering alinement so that the heated gases will be caused to flow in directions across the faces of the dues. Each of the fines 15, 18, and 2O being provided with the usual clean out openings closed by the usual doors or closures 21, it being understood that the said entrance openings are of a sufficient size to permit the baffles to be freely inserted into the flue and as freely removed therefrom.
All of the above referred to parts are of the ordinary and well known construction and constitute no part of the present in- The numeral 22 designates an annular baiie member constructed of any suitable material and of such a weight that it will be maintained in place when inserted into the flue.
The member or element 22 is preferably of a frustro-ccnical shape and is provided with spaced lugs 23 projecting beyond one edge thereof and spaced lugs 24 projecting beyond the opposite edge.
This member is adapted to be'inverted and Will be supported by means of the lugs23 or 24 according to the position of the element and Which lugs constitute supports Vor feet for holding the edge of themember or element above the bottom ofthe lflue andthe lugs being spaced they will not interrupt lthe flow of heated gases beneath or above the member 'or elementhin the event that y'the relpective lugs should-engage the top of the ue. v
number of thesebaflle members or elements 2Q may be provided accordi-ngftov The vgases Will be directed by the batlies against the WallsV of the -flue'and-they will also flow through the spaces between the baffles-and in a tortuous path before passing out of the fflue.
If desi-red some ofthe baille elements may be formed-o'fsections Q5 securedltogether-V in any suitable manner such as by means of bolts lor* screws passi-ng through apertured ears or lu-gsQG -on the sections thereby facilitatingthe'insertion of the baffle elements.
ln placing the battles in position lthe finnermostbaile Aelements Vmay be nested andfinsertedI together after which theV sectional members may lbe putin position about zthe otherV members and -thelsections secured together. By reason of the -frustro-conical shape of the l'baille members they may be arranged in the positionv shoivn in I `igUre 2 so that the anglel o-finclinatien'of the memberswvill be opposed to the entrance of the gases, the gases in this instance entering through a centrally arranged flue 16. J
Vihen the entrance Iflues 17%(see Figure l) arearranged-adjacent the periphery of the boiler-section the baffle members are inverted to the position shown in Figure l in the 'flue 1S-and thef'hei-ght'of the Irespective baffle members is sucht-hat the lowermost baille Willfbelfirst contact-ed by the-heated gases.
T-heflugs-QB-Qt formingfeet Will Contact with a minimum area of the flue Walls and so as inot-to cover any great surface of the number y-of ballesmay `be'e1nployed,ftheir Weight being such that they Will be'mainy.gained in position after being placed in the lllQ.
lith this invention it will be manifest that the hot gases Will be interrupted in their passage through the flues and will be directed against 'the Walls of the ilue and at the same time they Will flow-4in a tortuous passagev throughV the v`flue's With the result; that all. the heating units will be utilized will be reduced to a and the stack heat minimum with the further result 'that the efficiency ofthe boiler Willbe increasedfanc'l the fuel consumption materially reduced, 'at the same time the baffles may be readily mserted into a vflue and as re'adilyremo'ved Without departing from the spirit of 'this' invention. y
