Application December 13, 1949, Serial No. 132,715
1 Claim. (Cl. 122-381) The invention relates to boiler cleaners of the type comprising piping positioned within the boiler and having nozzles, through which nozzles scum, scale and other foreign matter is forced by pressure within the boiler and through a centrifugal action into the nozzles, and has for its object to provide a device of this kind which may be applied to any conventional form of boiler without modifying the construction of the boiler.
A further object is to provide the loop conduit within the mud collecting portion of the boiler with an extension nipple extending into the blow olf pipe so the device can be attached to the blow oi pipe without modifying the present construction of the blow off pipe connection to the boiler. This is particularly advantageous in boilers used in oil fields and the like.
A further object is to provide a blow oif nozzle having vertical slots and inwardly curved iianges for setting up a centrifugal action as the scum is forced through the nozzle incident to the pressure on the water above the liquid level Within the boiler.
A further object is to provide the upper end of nozzle vanes with a closure which will prevent incrustation and scale from falling in the scum nozzles at the top thereof, thereby obviating clogging of the nozzles.
A further object is to close the upper ends of the nozzles so that during a scumming operation,
steam circulation or vortex, which will create a 3 greater vacuum in the center of the vortex for the scumming operation.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed Without departing from the spirit of the invention.
In the drawings:
Figure l is a vertical longitudinal sectional view through a conventional form of oil field boiler, showing the boiler cleaner applied thereto.
Figure 2 is a collective detail perspective view of one of the nozzles showing its end closure disc in position to be placed on the nozzle and secured thereto.
`Figure 3 is a top plan view of the nozzle.
Figure 4. is a vertical transverse sectional view through the nozzle.
Figure 5 is a perspective View of a short open end nozzle used in inverted position in the :mud drum. g
Figure 6 is a horizontal sectional view taken on line 'S-S of Figure l.
Figure '7 is a vertical detail sectional view taken on line 'l-l of Figure 6.
The present invention is an improvement on the nozzle shown in Patent #2,006,283 issued to Joseph Staempfli, and No. 1,888,515 issued to John H. Stockholder, and overcomes the difliculties experienced with these two nozzles.
In the drawing, one type of boiler is shown such as used in the oil fields, however it is to be understood that any type of boiler may be used.
Referring to the drawing, the numeral designates a conventional form of oil field boiler having a-tube chamber 2 and a mud collecting portion 3 below the chamber. Disposed Within the chamber 2 above the tube space l thereof, and below the Water line 5 is a conduit `6 having at spaced intervals thereon nozzles l of the type shown in Figure 4. Connected to conduit 6 is a downwardly extending pipe 8 terminating at its lower end in a loop conduit 9 within the mud collecting portion 3 of the boiler. Loop conduit 9 is provided with downwardly extending nozzle l0 of the type shown in Figure 5. The nozzles l B are downwardly disposed so that pressure will force mud therethrough, and it will be seen that it is not necessary to close the ends of the nozzles lll, as in the case of the upper nozzles l. A blowoff pipe Il is threaded at l la into a plate connector llb secured to the rear side of the portion 3 of the boiler, as clearly shown in Figure 7, and the blow-off pipe is provided with a blow off valve l2, which valve is opened when it is desired to clean the boiler.
The nozzle bodies are cylindrically shaped and provided with vertical slots I3 and bent in anges i4 so the vertical slots will form elongated openings. When the valve I2 is opened, after the water level -5 has been slightly lowered, the pressure in the upper portion of the boiler on the column of water and the surface, having scum thereon, will force the upper surface water and scum through the nozzles, and during this operation, a whirling or vortex is set up in the usual longitudinal movement of the Water in the boiler in the direction of the arrows, Figure 1, and the scum will be forced through the nozzles and from the boiler and through the conduits 6, 8, nipple l lo and through the blow off pipe ll, and at the same time mud will pass through the nozzles Hl, and through the pipes 9, the nipple Hc and blow off pipe Il.
In use, it has been found that if the upper ends of the nozzles 'I are closed, as shown in Figures 2 to 4, the nozzles will not be clogged by the fall of incrustation and scale from the upper wall of the boiler, and at the same time by closing the nozzle ends a greater water and steam circulation, and vortex is created which creates a greater vacuum in the center of the vortex. To accomplish this result the upper ends of the nozzles are closed by a disc I5, which disc is preferably Welded at I6 to the upper ends of the nozzles. Although the closure i is shown as flat, it is obvious it can be any shape, for instance conical.
From the above it will be seen that a boiler cleaner nozzle is provided which has the advantages of the vertical slots and inturned varies with the additional feature of a closed upper' end which will prevent clogging of the nozzles, incident to falling incrustation from the upper wall of the boiler. It will also be seen that the closed end increases the vortex around the nozzle so the entire pressure above the liquid level will force the scum into the sidesof the nozzles and not axially downwardly through the nozzles.
The invention having been set forth'what is claimed as new and useful is:
The combination with a horizontal boiler, the rear end of said boiler having a downwardly extending walled mud collecting chamber, a fire box disposed in said rear end of the boiler, said re box having its walls spaced inwardly from the walls of the walled mud collecting chamber and the bottom of the mud collecting chamber,
said cleaner comprising a scum line within the upper portion of the boiler, said scum line being slightly to one side of the vertical longitudinal center of the boiler, the rear end of the scum line extending over the upper side of the fire box, scum nozzles carried by said scum line. a mud collecting portion disposed in the bottom of the mud chamber, said mud collecting portion being angularly shaped and extending around the sides of the mud collecting chamber adjacent the walls of the walled mud collecting chamber and comprising opposed U-shaped sections having their forward arms connected together by a T on the vertical longitudinal center of the boiler, a nipple carried by said T and extending through the opening in the wall of the walled mud collecting chamber and the ange and terminating adjacent the outer side of the flange and telescoping into the blow-off pipe, said mud collecting portion having downwardly extending blow-01T nozzles engaging the bottom of the mud collecting chamber and a vertically disposed off-center portion connecting the scum line and the mud collecting portion to one side of the nipple carrying T.
