The invention relates to watertube boiler constructions, and particularly to baffle walls,
as used in boilers of a wide 'variety of types,
, such as, Sterling, Connelly, Heine and others,
in which the tubes are uprightin general direction and parallel or approximately so. The
, invention has for its primary objects the proiolr vision of a baffle wall, whose construction involves a saving of time and labor; the provision of a composite wall partially of plastic refractory material hardened in place, which Vismore resistant to heat and more durable i j than the baffle walls heretofore used composed entirely of plastic refractory material hard- 15 ened in place; and the provision of a baffle wall, whose body portion is of plastic refractory composition hardened in place, which may be constructed without the wood forms heretofore ordinarily used. One embodiment of the invention is illustrated in the accompanying drawings, wherein: Figure 1 1s avertical section through one I type of water tube boiler employing the iin- 1 yproved baffle wall. F ig. 2 is a fragmentary.

Fig.,3 is a section on the line y liii-iii of Eig. a And Fig. 4 is a Section 0., y, Y 10and 11', the gases ofcombustion followingk the path indicated by-the arrows and dissimilar to that of VFigp3 through a'modilied form of the invention. 30`
Referring to the drawings, 1 is .the lower vdrum of a water tube boiler, 2y is the upper drum, land 3, 4 and 5 are `the front, middle and rear banks of vtubes respectively. In the particular construction shown, which is inerely one `of alarge number in which the imf proved baffle maybe usedthe boiler is fired by suitable Igas burners' directed through Vthe openings 6 and 7 but any form of firing may be used. The front baffleis made up of the parts Sand 9, and the rear baffle of the parts i .charging through the flue 12. The parts 8 and 10 of the baies, which constitute the novel subject matter, are constructed in ac- Cordance with the showing in Figs. 2 and 3, while the sections 9 and 11 are of ordinary construction, each consisting of a layer of originally plastic material hardened in place, suph compositions being well known in the ar A As shown in Figs. 2 and 3, the wall 8 consists 0f strips or blocks 13, 13, 13, etc. of preinolded refractory material, such as, brick or tile, of any desired length and just wide enough to bridge the spaces between ythe tubes, the edges of the strips being preferably beveled, as shown, inv order to fit the curve of the tubes. Between the sets of strips as thus provided is a filler or body portion 14 of the socalled plastic refractory material heretofore referred to. i
In fabricating a wall, such as the wall 8, the strips or blocksy 13, 13, 13 on one side of the spa/ce between the tubes to be filled, are first all putin position followed by the bottom row of 'opposing strips, and the space thus providedis filled with'the plastic material lll.
The next row of strips is then positioned on i also harder than the plastic material and will stand the attrition from dust better. `Where wood forms are used in constructing a wall, which is all plastic material, such forms are difficult of removal, and if left to be burned out sometimes conceal cracks and voids in the plastic material which must then be patched or repaired involving additional expense and labor. The use of the tile or brick blocks avoids this difficulty, as the refractory facing as thus provided compensates for any cracks or defects existing in the plastic filler.
`The invention also contemplates a modification of the wall, as just described, such modi- Vfication being illustrated in Fig. 1. As here shown, the brick or tile blocks or strips 13, 13, 13 are placed on one side only of the layer of plastic material 111. This construction, although not as desirable as that of Fig. 2, may be used to advantage under certain conditions, the strips 13,155,113, etc. being placed on the side of the wall which is exposed to the greatest heat. Vood forms may be used to hold the plastic material on the side opposite to v the strips 13, such forms being either removed after the plastic has set or else left in the furnace and burned out. f
