4 Claims. l
My invention relates to boiler wall constructions, and more particularly to a pressure part supported wall for boilers.
In boilers it has been customary to mount the walls of refractory material on a framework that was entirely independent of the boiler structure. This necessitated the use of a Very large amount of steel for supporting the wall, and it is a purpose of my invention to provide a mounting for walls for boilers that eliminates a large portion of the steel frame structure that was previously necessary.
It isa particular purpose of my invention to provide a pressure part supported wall for boilers whereby about half the weight of the steel that was previously required is eliminated and whereby the structure is considerably simplified to reduce the expense of construction thereof, the engineering work as well as the erection cost and the cost of the steel being reduced by my simplified mounting for the frame members for supporting the walls of boilers.
It is a specic purpose of my invention to provide inV combination with a boiler having a pressure part, a wall of refractory members supported on or by said pressure part, said wall being, preferably, sectionally supported by means of a framework that comprises upstanding frame members supported by the pressure part and on which the sectionally supported wall is mounted.
My invention contemplates the use of boiler drums, headers and similar tubular members forming part of the boiler structure as a portion of the framework, by securing certain of the frame members directly to such boiler parts, as above referred to, and the provision of means in the connections allowing for a limited movement to compensate for the expansion of the boiler structure when the parts become hot.
One of the important purposes of my invention is that by utilizing my improved Wall structure av tighter wall can be obtained because the spacing of the columns or upstanding members will increase when the drums and headers or similar parts to which the same are secured become hot, which would result in a general expansion of the wall that would be taken up by the slight breathing in each section between the columns rather than by providing slip seals between the wall and other parts, such as the roof and oor, at which all the expansion would otherwise have to be compensated for. By hanging the arch at the top of the wall and at the boiler drum, the seals between this'arch and the drum can be permanent insteadV of a sliding seal, thu's further `pro- Viding a tighter structure.y
heat to which the refractory members I9 are sub- Other objects and advantages of my invention will appear as the description of the drawings proceeds. I desire to have it understood, however, that I do not intend to limit myself to the particular details shown or described, except as defined in the claims.
VIn the drawings:
Fig. 1 is a vertical sectional view, partly broken away, of a wall constructed in accordance with my invention, showing fragments of the oor and roof.
Fig, 2 is a fragmentary detail sectional view on a somewhat enlarged scale, and
Fig. 3 is a fragmentary vertical sectional view through a boiler construction embodying my improved wall construction, showing a drum for supporting certain of the frame members.
Referring in detail to the drawings, in Fig. 1
is shown a boiler structure in which there arev headers I9 and II between whichthetubes I2v extend, said tubes being secured to the headers in a well known manner. A bracket I3 is provided on the header I0, being secured thereto by welding, and a bracket I4 is secured to the header l I in a suitable manner, yas by welding. Vertically extending frame members I5 are secured to the brackets I3 and I4, the brackets I3 being secured to the frame members I5 in xed position by means of bolts I6. The bracket members I4 are secured to the upper ends of the framemembers VI5 by means of bolts I'I, which extend through openings in the frame members I5 and throughv slots I8 in the brackets I4 to thus provide for a limited relative sliding movement between thev brackets I4. and the frame members I5.
The refractory members I9, of which the wall* is constructed, are shown more in detail in Fig. 2.
Said refractory members are sectionally mounted on the framework, of which the vertically extending members I5 are the columns, by means of horizontally extending members 20, which are secured to the vertically extending frame members I5 and upon which hanger members ZI areA mounted, which support the refractory members I9 sectionally, that is, each of the hanger members ZI supports a plurality of vertically adjacent The specific construc-l refractory members I9.
tion of the sectional supporting means may be varied and does not form part of my invention.
The hanger members are protected from the jected by means of a layer of heat insulating ma terial 22. members I5 may be of any desired shape, and in the form of the invention illustrated these have lower ends 23 reduced in size to provide for the The columns or upstanding frameoutwardly directed portion of the wall that lies opposite the bends 24 in the tubes I2 at their lower ends.
The header II may also be provided with a bracket 40 welded thereto, which has a horizontally extending portion 4I, that is provided with slots 42, through which the headed fastening elements 43 extend for securing the horizontal frame member' 44 to said header so that there will be a limited longitudinal sliding movement between the frame member 4.1i and the bracket. Said frame member 44 extends between the header member II and a similar header member or other pressure part with which it is connected in a similar manner to that shown.
The frame members 4d are utilized to suspend the refractory members t5 by means of suitable hanger members 46 carried by the transversely extending members 41 or in any similar manner, and heat insulating material 22 is provided between tlie refractory members and the metallic hanger means carried by the frame members 4:4.
My invention further includes a framework for a sectionally supported wall, such as shown in Fig. 3, in which the drums 25 and 26 of the boiler are shown, which have the tubes 2T connecting the same. The refractory members I9 of the upstanding wall are sectionally supported in a similar manner to that previously described, by means of horizontally extending members 2s that are mounted on the vertically extending frame members 28, which are supported at their lower ends on any suitable support 35, such as a oor or foundation. The refractory members I9 of the arch shown in Fig. 3 are suspended from inclined frame members 2s and said arch is thus also sectionally supported. Said inclined frame members 29 may be connected together by means of transversely extending frame members 30, from which hanger brackets 2i are suspended.
The inclined frame members ,29 are secured at their upper ends to the drum 26 by means of brackets s! that are secured to the drum in any suitable manner, as by means of welding, and said inclined members are secured to the brackets 3l by suitable bolt-like members 32 that pivotally secure said inclined members to said brackets. Brackets 33 are secured to the lower ends of the inclined members 29 and said brackets are secured pivotally to the upper ends of the upstanding members or columns 23 by bolt-like members Se that pivotally connect said brackets with the columns 28 and thus pivotally connect the members 2B and 29 together.
Suitable heat insulating material 38 is provided between the wall of refractories I3 and the metallic frame structure, and a similar insulating covering 3l is provided for the refractory meinbers I?, of the arch, which are suspended Afrom the hanger brackets 2i in a suitable manner. An insulating covering 33' is also provided for that part of the drum '25 that lies above the arch.
It will be obvious that when the boiler is in operation the heat eiu'sting in the parts 25 and 26 will cause expansion thereof and the pivot connections at 32 and Sli will permit a swinging of the inclined members 2s to compensate for this expansion of the parts and greater spacing of the members 25 and 2E from each other when the boiler structure expands as heating takes place, thus providing for a relative movement between the upstanding members 23 and the inclined members 2s of the framework.
It will further be noted that both in the use of the headers I and II as framework members and of the drum 25 of the framework member, all heavy frame members extending horizontally for supporting the upstanding members I5 and 28, as the case may be, are entirely eliminated and thus the cost of construction is greatly reduced and much material is saved. In View of the fact that the pressure parts IIJ, I I and 26 and similar pressure parts of a boiler are made of great strength to withstand the pressures in boilers of the character with which my invention is used, the same are of adequate strength to support the vertical frame members I5 and the inclined frame members 29 and the frame members 28 and the walls supported thereby, and accordingly no additional horizontal frame members are necessary for sectionally supporting the walls made up of the refractory members I9.
