Definitions
- the present invention relates to tube heaters, and more particularly to supports for holding the passes of a tube coil in position in a tube heating furnace.
- the fluid to be heated flows back and lforth through the passes of a horizontally disposed, serpentine tube coil or bank.
- the varlous passes of the coil must be supported as they are being heated.
- the supports heretofore used are structures rigidly attached to the furnace, and are strong enough to withstand the lateral thrust created as the various passes expand and contract due to temperature changes in the furnace. With a coil having each pass fifty feet long, the expansion could be eight or nine inches.
- FIG. l is a sectional View through the furnace chamber
- FIG. 2 is an enlarged view of the upper portion of the tube support
- FIG. 3 is a view taken from the right of FIG. 2 showing an entire support.
- FIG. 1 there is a section through a furnace which has a chamber surrounded by side Walls 1, door 2 and a roof 3.
- the chamber is elongated in a direction perpendicular to the drawing and is heated by horizontal, parallel rows of burners 5 which are shown herein as being of the radiant cup type.
- the products of combustion from the burners are exhausted through a stack 4 to one side of the roof of the chamber.
- the furnace is used to heat a pair of vertically disposed tube coils, each of which consists of a plurality of horizontal disposed passes that are connected in the usual fashion by return bends.
- the passes of one coil are indicated by the numeral 6, while the passes of the other coil are indicated by the numeral 7.
- These coils are supplied respectively with iluid to be heated by pipes 8 and 9.
- the arrangement of the coils and of the ow of the material through the Vcoils depends upon the type of pyrolysis that is being practiced in a particular furnace. As shown herein, the coils are joined at their lower ends by a common discharge through pipe 10.
- the coils are supported in the furnace by means of tube supports 11, a number of which are spaced along the length of the furnace. Usually these supports will be from 6 to 8 feet apart.
- the tube supports are suspended from a portion of the structural steel work 12 of the ice furnace.
- a plate or hanger 13 which is rigidly bolted to the structural steel and which extends through a small opening in roof 3. The space between the sides of the opening and the plate are preferably closed with cement.
- Tube support 11 has on its upper end a fork or yoke 14, the lingers of which receive between them the lower end of plate 13.
- the plate and yoke arms are provided with openings through which pin 15 extends.
- the openings 16 in the yoke ngers are larger than the .pin so that the support can swing freely around the pin in a direction parallel to the direction in which the tube passes extend while plate 13 prevents the support from swinging sideways.
- Each support is provided with a plurality of oppositely extending arms 17 on which the passes of the respective tube coils rest. In some cases it may be desirable to weld small knobs 1S to the bottom of the lowermost tube pass, as shown in FIG. 3 of the drawing, for a purpose which will be described below.
- the tube supports 11 can pivot around pins 15 as the tubes expand, so that the bending force of the tubes on the supports, as well as slipping of the tubes on arms 17, is materially reduced.
- the upper tube passes where the fluid being heated is coolest will expand less than the lower passes where the tube is hottest. Since, however, the pivot 15 is closest to the cooler tubes, the greater expansion of the lower tubes is automatically compensated for.
- the knobs 18, which may be welded to the bottom tube pass on opposite sides of an arm 17, will engage the arm and move it around pivot 15 as the tube expands. This will prevent any binding of the pivot. In addition, the knobs will only permit the tube to slide on the arm, in any event, an amount determined by their spacing.
- a furnace said furnace being adopted to heat serpentine tube having horizontally disposed passes one above the other, said furnace having a chamber in which the tube is disposed and a roof over the chamber, supr porting structure above the roof, a plate attached to said structure and extending through the roof into the chamber, an elongated support member, a plurality of tube supporting arms projecting at diterent levels from opposite sides of said member for supporting the horizontal passes of the tube, and means mounting said member from one end on the portion of said plate in said chamber, said mounting means being operative to permit pivotal movement of said member on said plate only in a direction perpendicular to the direction in which said arms extend and parallel to said tube passes.
- said mounting means comprising a pair of parallel lingers extending from an end of said member to receive said plate between them and a pin extending through said lingers and said 4 plate, said pin extending in a direction parallel to said arms.
