S'IEAM- BOILER.
Application' filed September 5, 1923.. Serial No. 661,017.
1 structure constitutes a part ofthe circulating system of the boiler, as ill be hereinafter .described and claimed.
The invention is herein illustrated in connection with a water-tube boiler of the character described in Letters Patent of the United States No. 1,442,433 dated January 16, 1923, but it is to be understood that the improvements are equally applicable to water-tube boilers of other forms or types.
In the drawings- Figure 1 is a longitudinal vertical section of a battery type of boiler embodying my invention. I I
Fig. 2 is a transverse section'of-the boiler, as on the line 2-2 of Fig. 1.
Referring to the drawings, 10 designates the'boiler setting, which, in the present illustration, is medially divided by a central partition wall 10 to afford two chambers or compartments for the respective boiler units. 11 designates one of the combustion chambers, and 12 designates the outlet or breeching to the smoke stack at the rear of the setting. 13 designates a mud drum at the rear of the bridge wall of each combustion chamber; 14 a water drum located above the forward portion of the said chamber and below the normal water level, and 15, 16 two steamand-Water drums arranged above the drums 13, 14, respectively. The drums 15, 13 and 14 are connected in succeeding order by banks of tubes 20, 21, 22 respectively, thereby providing a continuous circulation path for the boiler water. The steam spaces of the two upper drums are connected by overcomer tubes 24 whereby the steam which is disengaged from the water in the drum 15 flows into the steam space of the front upper drum, whence it is removed for service. The water spaces of the upper drums are connected by means of opposite- flow tubes 26, 27 which function to establish a supplementary water circulation between the two drums and maintain therein a uniform water level, as
of a cap 30.
more fullyrdescribed in Patent No. 1,442,433 aforesaid. 7
Suitable. baffling is arranged within the boiler setting to provide succeeding passes for the hot gases in their course from the combustion chamber at the front to the outlet atthe rear of the setting, includes a main-transverse wall 28of firebrick or other refractory material, supported directlyabove "the lower tube bank 21 that overhangs the combustion chamber, and also a Wall 28' located within the bank of tubes 20 to extend from the drum 15 to ra planesomewhatabove the mud drum 13. .As illustrated'these baffle walls provide twoup and one down serial passes for the gases between the cornbustionchamber and the outletor off-take. The wall 28 is s'ustainedby a'basal girder 29 supported in the boiler setting, which girder, in large boilers,has an extensive span and must, for safety, be protected from the destructive action of the hot furnace gases. Accordingly, provision is made for the efficient water cooling of the girder as follows: The girder comprises a hollow trunk-like structure which is supported at its ends in thew-alls of the boiler setting, the outer end, in the present instance, being conveniently closed by means The girder is communicably connected adjacent each end thereof to the top of the mud drum 13 by means of a tube 31, and it is also similarly connected, about midway between its ends, to the bottom of the rear stean1-and-water drum 15 by means of one or more tubes 32, such girder and tubes being exposed to the hot gases in their travel. By this construction a water circuit is established between the drums 13, 15 and the girder, and, in consequence, there is maintained throughout the interior of the girder a continuous circulation of boiler water which effectually protects the girder walls from the destructive action of the hot furnace gases; and since the girder and its tube connections constitute an integral part of the circulating system they serve efficiently to augment the heating surface of the boiler. It is to be noted that the placing of the tubes 31, 32 in the path of the gases, and especially the arrangement in the upper and hotter portion of the down pass, ofv the tubes 32 which connect the support with the steam-and-water drum 15, materially assist which bathing in causing a rapid circulation of. water through the support, thus ensuring an officient cooling effect of the water on the support.
It is to be ui'iderstood that my invention is I not limited to the structural details herein disclosed, as the construction may be media tied within the principle oi": the invention and the scope of the appended claims I claim 1.. A water tube boiler comprising a set ting having a combustion chamber therein and an off-take tor the products of combustion, a mud drum, a steam and water drum, water circulating tubes connecting the mud drum to the steam and water drum, a battle forming serial passes for the gases between the combustion chamber and the oft-take, a hollow water cooled support for said bafiie,water circulating connections between the mud drum and the hollow support in the path of the gases, and water circulating connections between the hollow support and the steam and water drum also in the path of the gases and in a hotter portion of the pass than the connections between the hollow support and the mud drum.
2. A water tube boiler comprising a setting having a combustion chamber therein and an oft-take for the products of combustion ,-a mud drum, a steam and water drum, water circulating tubes connecting the mud drum to the steam and water drum, a plurality of bafiles forming two up, and one down serial passes for the gases between the combustion chamber and the ofi-take, a hollow water cooled support for the baffle between the first and second pass, water circulating connections between the mud drum and the hollow support in the lower portion of the down pass and in the path of the gases, and water circulating connections be tween the hollow support and the steam and water drum in the upper portion of the down passand also in the path of the gases.
3. A water tube boiler comprising a setting having a combustion chamber therein and an off-take for the products of conibus.
connections between the mud drum and the hollow girder, and circulating connections between the girder and the steam and water drum in a down pass for thegases.
4. In a water-tube boiler comprising a setting, a combustion chamber, an upper steamand-water drum, a lower'mud drum, an intermediate water drum, banks of tubes connecting the drums in successive order, and bathing, including atransverse wall of refractory material, a hollow water cooled girder upon which said wall is supported above the tube bank leading from 'the'mud drum to the water drum, tubes connecting the respective ends of the girder to the mud drum, and an intermediate tube connecting thegirder to the said steam-and-water drum, said girder and its connecting tubes being arranged in the path of the gases from the combustion chamber.
