STEAM' BOILEB@ Application mea January 2o, 1920.A seriai No; 352,678.
To all whom t may concern:
Be it known that we, -DAVID S. JAOOBUS and JOHN WOLFE, citizens of the United States, and residing at Jersey City, county of Hudson, and State of New Jersey, and
East Cleveland, in the county ofv Cuyahoga and State of Chio, respectively, have invented certain new and useful Improvements in Steam Boilers, of which the following is a 1o specification.v f
Our invention more particularly relates toan improvement in a boiler in which a boiler part or part-s, Such as a mud drum and the metallic supporting members therefor, which are to be protected from the'furnaceheat,
are located `above the Stoker, and -in'which an ignition arch is located between. thev A Stoker and the parts to be protected and affords protection to such parts. In 'practice, the innere-nd of such an arch is liable to fail, and in case of failure the boiler parts are exposed to the furnace heat and injured unless the Stoker is promptly shut down.
In accordance with our present invention, a bridge wall is located-immediately above the arch and in front of the parts to vbe protected `and is supported independently of y the ignition arch so that a failure of the ignition archdoes not affect the protection af- :forded ,to said parts.
Other objects of our invention will appear inthe specification and will be particularly pointed .out Iin. the claims. f
Referring, now, to the drawings,.-Figure 1 is a longitudinal sectional view of a steam boiler of the Stirling type, in conjunction with which `we have illustratedour invention, and Fig. 2 is a'detail sectional View similar to Fig. 1, but illustrating the parts with which Aour present invention ,is concerned on a larger Scale. j
Referring, now, to the drawings, in which like reference characters indicate like parts,
drums of a steam boilerof the Stirling type, in conjunction with which we haveil-lustrated our invention, connected to a lower mud drum 13by banks voftubes 14,15 and 16, respectively. `The gases fromthe furnace 5o upwardly from themuddrum 13 back of the front row of the. first bank of tubes, therbaf- 10, 11 and 12 are the upper steam and water' are directed serially overthe tubes `baf-Y fies 17,18, 19 and 20, the baffle 17 extending' steam and water drum 11 back of the front row of tubes of the second bank 1S, the baffie 19 extending upwardly lfrom the mud drum immediately back of the second bank of tubes 15, and the baffle 2O extending downwardly from the steam and water drum 20 between 'the tubes of the last bank 16, the baile 19 preferably being provided with a transverse projection 19fL which directs the gases among the front rows of tubes of the last bank as 'they pass downwardly. The gases pass in the general direction indicated by the arrows, and escape through the outlet 21;` The setting for the boiler is indicated at 22'.l Beneath the mud drum 13 is disposed a Stoker 23,`which is here shown as of the chain grate type. Above the Stoker and beneath the mud drum is disposed an ignition arch 24 which is supported from metallic members 25',-he`re shown as channel irons, in aknown'manner, it being understood that ignition archwis abroad expression, covering anyrefractory roof above the furnace, either suspended or otherwise supported, orv flat or of other form. Above the inner end of thc ignition arch 24 is disposed a bridge wall, which is indicated, in general, by the reference character 26, and which comes in front of the mud drum 13. This bridge wall is supported by metallic members, such as I- beams'27, extending transversely across the furnace, and comprises an arch 28, which is locatedv immediately above the ignition archv24, and which is suspended from the metallic members r`27 in any of the well known ways; such' as by hooks engaging the ianges of the I-bea'ms 27 The 4bridge wall alsozcompri'ses afwall 'proper 29 carried on the I-beams 27, a section 30, which may be formed of tiles, being disposed between the arch 28 and the wall member 29, and resting on the arch 28'. A dust floor 31 is preferably located at vthe rear of the bridge wall and forms a gas-tight joint therewith and with the setting 22. The dust Hoor 31 partially encloses a portion B of the passage which conducts thegases from the furnace. No'casing is built up at the front of the space `A between the ignition arch and the dust oor 31, so that this space is freely eX- posedto. the atmosphere. By leaving the space A free-to the atmosphere there is no tendency to draw the hot gases from the furnace tl'irmiglil cracks in the ignition arch or `harder to maintain the than that within the furnace, withthe re-` sult that there would be leakage from the furnace through the roof 24, as well as through the brickwork which comes above the inner ond of the ignition arch. The suction within the space B is considerably greater than that within the furnace and it willreadily be seen that any leakagey through the partition between the spaces B and A would tend to increase the draft suction in the space A, should the space A be encased, to a point wherethe Adraft suction of `A would be higher than the draft suctionv Within the furnace. For example, the draft suction at B might be 111A. lVith no casing to enclose the space A, the draft suctionin A would remain Zero. Should a casing be added, the draft suction in A might be as high as l, whereas, the draft in the furnace might be, say .6, and the result would be a tendency for the hot gases to be drawn outward through the brickwork and into the space A. Where there is a tendency to draw the hot gases outward and the gases percolate slowly through the brickwork, it is much brickwork than where the cold air percolates slowly through the brickwoik and into the furnace. In fact, in many instances, the percolation of the hot gases outward as compared with the percolation of the cold vair inward makes all the difference between a failure and a suc-V cess of the installation.
Thile we have herein shown and described one modification of our invention, we do not desire to be limited to the exact arrangement lshown and described, but seek to cover, in the appended claims, vallthose modifications which come within-the true` spirit andy scope of our invention;
What we claim and desire to secure'by Letters Patent of the United States is:
