Patented Oct. 1, 1929 UNITED STATES PATENT OFFICE LEMUEL V. REESE, OF ERIE, PENNSYLVANIA, ASSIGNOR T0 ERIE CITY WORKS, OF ERIE, PENNSYLVANIA, A CORPORATION 0F PENNSYLVANIA FURNACE Application led December 22, 1926. Serial No. 156,495.
This invention is designed to improve furnaces for burning types of fuel subjecting the furnace to slagging temperatures. Vith such furnaces it is desirable to separate the floor of the ash pit from the body of the chamber in order that the slag may be chilled prior to reaching the ash pit so as to prevent agglomeration in the ash pit. Such a furnace has been illustrated and described in the patent to Frederick Seymour, #1,355,172, dated Oct. 12th, 1920, and the present furnace is in the nature of an improvement of said Seymour furnace. Features and details of the invention will appear from the speciiication and claims. l
The invention is illustrated in theaccompanying drawings as follows F ig. l is a vertical sectionof the furnace on the line 1-1 in Fig. 2.
Fig. 2 a horizontal section on the line 2-2 in Fig. 1. y
Fig. 3 a section on the line 3 3 in Fig. 2.
Fig. 4: a perspective view of one of the tile.
1 marks the furnace chamber, 2 a boiler which, as shown, is of a conventional threedrum type although the furnace is not limited to a boiler furnace, or to a boiler of this type, and 3 the fuel delivering means, as shown of a type to deliver pulverized fuel. Water tubes 4 are arranged in a plane slightly inclined from the horizontal across the furnace chamber above the ash pit and these tubes are connected to a front header 5 and a rear header 6. The header 5 is arranged in a recess 7 arranged in the front wall of the furnace and a header 6 in a recess 8 in the rear Wall of the furnace. The headers are provided with hand-holes opposite the tubes and these hand-holes are provided with covers 9. By reason of the recesses and the arrangement of the hand-holes the tubes may be readily cleaned and replaced fromywithout the furnace. r
The tubes are preferably arranged in pairs and a tile covering is arranged over each pair leaving an intervening space between each pair. These tile coverings are preferably sloped towardtheir edges so that any deposit upon the tile is carried to the edge and drops into the ash pit. The tile coverings are formed of tile 10 which are preferab y V-shaped as shown and have grooves 11 .at their bottom edges. The tile are placed on the tubes, the tubes seating in the grooves to hold the tile in place. With this .method the tubes may be sufficiently cooled to prevent the deposit of liquid ash in the bottom of the ash pit and thus agglomeration of the slag is prevented. On the other hand the tile may be so extended as to confine the' chilling eect with relation to the combustion portion of the chamber as desired.
It will be noted that the major portion of the tube beneath the tile is directly exposed, thus adding' to the cooling effect upon the ash pit and thus preventing to a large extent agglomeration in the ash pit. It will also be noted that the tiles can .be directly removed in a direction transverse to the axis of the tiles so that a single tile may be replaced without taking in any larger portion of the tile system.
What I claim as new is 1. In a furnace, the combination of a fu-rnace chamber having water tubes in pairs and in a common plane extending over the ash pit of the chamber; and tile bridging the space between the tubes of each pair, said tile being V-shaped having its edges resting on the tubes and sloping toward its edges.
2. In a furnace, the combination of a furnace chamber having water tubes in pairs and in a common plane extending over the ash pit of the chamber; and tile bridging the space between the tubes of each pair, said tile being V-shaped having its edges resting on the tubes and sloping toward its edges, and said tile being grooved at its edges forming a seat for positioningthe tile on the tubes.
3. In a furnace, the combination of a furnace chamber having Water tubes in pairs and in a common planeover the ash pit of the chamber; and tile bridging the space between the tubes of each pair, said tile closing the space between the pair bridged and leaving open spaces between the adjacent pairs, each tile extending from tube to-tube of the pair bridged exposing beneath the tile a major portion of the supporting tubes, the tile 100 having its up er face formed by inclined surfaces exten ing from the central part of the tile to the edge of the tile whereby the entire upper face of the tile is sloping.
5 4. In a furnace, the combination of a furnace chamber having water tubes in pairs and in a common lane over the ash pit of the chamber; and tlle bridging the space between the tubes of each pair, said tile closing the space between the pair bridged and leaving open spaces between adjacent pairs,
' each tile extendin from tube to tube of the pair bridged and etachable by a movement 1n a. direction directly transverse to the axis of the tubes and having its upper face formed by inclined surfaces extending from the central part of the tile to the edge of the tile whereby the entire upper face of the tile isl sloping.
2o In testimony whereof I have hereunto set my hand.
