1 Claim.

This invention relates to boilers, furnaces, retorts, and the like, and relates more particularly to supports or mountings for boilers and like equipment. A general object of this invention is to provide an inexpensive, particularly effective, portable boiler mounting.

In installing boilers in oil fields and similar places it is necessary to build suitable foundations of concrete, or the like, to mount the boilers. These foundations are expensive and require considerable time to build. If it is desired to move a boiler to a new location a new foundation must be provided and the foundation at the original installation is useless and, therefore, abandoned.

Another object of this invention is to provide a portable boiler mounting that may be quickly installed without expensive foundations and that may be readily moved when the boiler is moved to a new location.

Another object of this invention is to provide a boiler mounting of the character mentioned that is in the form of a single, compact, readily transported unit.

Another object of this invention is to provide a portable unitary boiler mounting of the character mentioned that is complete, including dependable supporting elements for the boiler proper, means for supporting the burner, and a dependable lining of refractory material.

Another object .of this invention is to provide an improved boiler mounting that increases the combustion and heating emoiency of the burner and, therefore, the efificiency of the boiler.

Another object of this invention is to provide 1 a boiler mounting of the character referred to that supports the burner below the fire box of the boiler to provide a larger combustion chamber, to maintain the flames under the boilenand to prevent the direct engagement of the flames with the plates and tubes of the boiler.

The various objects and features of my invention will be fully understood from the following detailed description of typical preferred forms and applications of the invention, through- I out which description reference is made to the accompanying drawings, in which:

Fig. 1 is a fragmentary side elevation of a typical boiler with its burner assembly, illustrating the manner in which the mounting of the present invention supports the boiler and burner assembly, the lower portion of the boiler and the mounting being in vertical cross section. Fig.

.2 in-an enlarged fragmentary vertical detailed sectional view of the mounting body and its lining Fig. 3 is an enlarged perspective view of the improved boiler mounting. Fig. 4 is an enlarged fragmentary vertical detailed sectional view of the mounting. Fig. 5 is a reduced vertical sectional view of another form of the invention with a part of the boiler in elevation.

The boiler mounting of the present invention may be employed to support boilers of various types and, of course, may be modified somewhat in construction for special or specific installations. In Fig. 1 of the drawings I have shown a typical oil field boiler B having the usual leg or fire box II and the tube or body I0 extending horizontally from the upper end of the fire box, The fire box II is open at its lower-end and, in accordance with theusual practice, its walls comprise spaced connected plates. The boiler burner assembly I2 shown in the drawings is a fluid fuel burner comprising arectangular frame I3, a plurality of jets I4 supported in the frame l3 to project from its upper surface and the fuel supply I5 provided with the usual air or draft control means Hi. It is to be understood that the boiler and burner structure illustrated are typical and are not to be taken a limiting or restricting the invention.

The improved boiler mounting of the inven tion shown in Figs. 1 to 4, inclusive, may be said to comprise, generally, a body II, legs I8 for the body H, a lining I9 for the body I1, and a water or steam coil 20 in the lining IS.

The body I1 is provided to support the boiler 13 being intended for arrangement under the leg or fire box II. In accordance with the invention the body I1 is a simple, rigid structure shaped to conform generally to the lower end of the fire box I I. It is preferred to form the body H of I-beams and in the case illustrated the body Il comprises two side members 2| and two end members 22 formed of I-beam stock. The

members 2| and 22 are connected to form a structure that is square or rectangularv in plan view and proportioned to substantially conform to the lower end of the boiler fire box II. The end members 22 extend between and connect the spaced side members 2| and in the particular arrangement illustrated the upper and lower flanges 23 of the end members 22 are cut back at their extremities to allow the webs of the members 22 to come against the webs of the side members 2|. The upper and lower flanges 24 of the side members 2| preferably occupy the same horizontal planes as the flanges 23. The members 2| and 22 are rigidly connected. Welding 25 may join the flanges 23 and 24 and the vertical webs of the members 2| and 22, The upper flanges 23 and 24 of the body members present large horizontal surfaces on which the fire box II may bear and which facilitate the ready connection of the boiler to the body I'I. Openings 26 may be provided in the webs of the members I'I adjacent the ends of the body I? to facilitate the lifting and transporting of the assembly.

The legs I8 serve to support the body I1 and form convenient, effective means for mounting the burner assembly I 2. The legs It may be sections of I-beams of selected width arranged horizontally to have base flanges 2'! and top flanges 28. The top flanges 28 are Welded or otherwise fixed to the lower flanges 24 of the side members 2I while the base flanges 21 may rest on foundation blocks or may be cast in concrete or the like. Vertical webs or braces 29 may extend between the flanges 21 and 28 at the outer sides of the legs I8 to strengthen the legs. The legs I8 may be flush with the opposite ends of the side members 2|. The inner sides of the legs I8 are provided with horizontal shelves or brackets 3G. The brackets 30 are fixed to the legs I8 as by welding and are spaced between the upper and lower ends of the legs. The brackets 30 serve to mount or support the burner assembly I2 in the base. Tie bolts 3| pass through vertical openings in the brackets 30 and transverse members 32 of the burner assembly I 2 to secure the burner assembly in the boiler mounting. The burner assembly I2 may be supported where the upper side of its frame I3 engages against the lower flanges 23 and 24 of the body IT and where the lower side of its frame is clear of the ground or support. It will be observed that the legs I3 support the burner assembly I2 so that the jets I l are in the lower portion of the body I? and a substantial distance below the fire box II.

The lining I9 serves to protect the body I? against the burner heat and further serves to contain or carry the coil 26. The lining I9 covers the inner surfaces of the body members 2I and 22 and as illustrated may be of substantial horizontal thickness to project inwardly beyond the flanges 23 and 24. The upper and lower surfaces of the lining I9 may be flush with the corresponding surfaces of the upper and lower flanges 23 and 24. The lining I9 may be formed of fire clay, fire bricks, or other refractory material, and may be cast or formed in the body I'I. It will be observed that the inner flanges or inner flange parts of the body members 2i and 22 serve as effective supports and retainers for the lining I9. The lining I9 covering the inner side of the body I! encloses a space for the flames of the burner unit I2 and thus defines a lower extension of the fire box I I. Where the lining I8 projects inwardly beyond the walls of the fire box II, fire bricks 34 or the like may be stacked or laid on the top of the lining to line and protect the walls of the fire box. Plates 9 may be welded or otherwise secured to the lower flanges 23 and 24 to assist in supporting the lining I9 in the body I! and the lining ma have internal reenforcements as required,

The coil 2i! may be employed as a preheating coil for the feed water of the boiler B or if desired may be employed as a superheater for the steam generated by the boiler. In accordance with the invention the coil 20 is cast or embedded in the lining I9 and it is preferred to locate or arrange the coil to lie relatively close to the inner surface of'the lining. The coil 20 may be of any selected capacity and may have as many convolutions as required. The inlet and outlet ends 35 of the coil 20 extend through openings in the body I? to be conveniently connected with the water or steam lines. The fluid handled by the coil 35 is, of course, heated by the heat conducted through the inner portion of the lining I9.

It is believed that the utility and practicability of the boiler mounting of the present invention will be understood from the foregoing detailed description. In installing the boiler B the mounting may be readily transported and installed as a unit. If desired the burner assembly I2 may be secured in the boiler mounting to be transported therewith. The mounting is quickly and easily installed by merely mounting its four spaced legs I8. The legs I8 may be arranged on any selected or available support or may be cast in blocks or a floor of concrete, or the like. With the boiler mounting in place the boiler B is quickly installed by merely resting its fire box I I on the base body II and if desired securing the fire box to the mounting body. In the operation of the boiler the fuel is supplied to the jets I4 in the usual manner and the heat of the burner flames serve to generate the-steam. The jets I 4 are located in the lower portion of the body I! and are therefore below the fire box II. Thus the improved mounting of the invention provides a larger combustion space and lowers the flames in the fire box to increase the efficiency and capacity of the boiler. With the flame lowered by reason of the location of the burner assembly in the improved mounting the flames are lower in the boiler structure minimizing injury to the boiler plates or tubes. The coil 20 embedded in the lining I9 is available as a preheater for the feed water or as a superheater for the steam. When the boiler is to be moved it may be readily detached from the improved mounting and the mounting may be freed for transportation. The mounting, with or without the attached burner assembly I2, is a compact, readily transported unit. The mounting may be employed to mount or support the boiler B in its new location.

Fig. 5 illustrates a form of the invention suitable where a high pressure burner I4 is to be employed. In the construction of Fig. 5 a pit Ed is provided under the leg or fire box II of the boiler B and the boiler mounting of the invention is positioned in the pit. The portable boiler mounting of Fig. 5 comprises a body I'I of suitable height designed to fit the pit 50 and to ac commodate the lower end of the fire box I I. The body H is of suitable construction, for example, it may be made up of a series of superimposed rectangular sections EN. The sections 5| are formed of I-beams or other stock and are suitably connected to form a rigid unit. The height of the body ll, of course, depends upon the depth of the pit 50. The mounting body II' may rest cnthe bottom of the pit 50 and the upper end of the body may extend above the pit to receive and support the lower end of the fire box II. A refractory lining I9 similar to the lining I9 is provided on the inner surface of the body II and a suitable lining 53 may be provided on the bottom of the pit 58. The high pressure burner Id enters through an opening 54 in the body ll and the lining Ill to discharge in the hollow body. The burner I4 may be directed downwardly and inwardly in the mounting.

The boiler mounting, shown in Fig. 5; has substantially the same features and uses as the previously. described mounting. The body I'I carrying the lining Is which may or may not embed thecoil 20, is readily transported as a unit and may be quickly installed in the pit 50. The body I? arranged inthe pit forms a convenient dependable mounting for the boiler B. If the boiler is to be moved the body I? carrying the lining l9 and the coil 20; where the coil is employed, may be removed from the pit and transported to the new location of the boiler to again mount the boiler.

Having described only typical preferred forms and applications of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the art or fall within the scope of the following claim.

er ally to the lower end of the fire box, the i I end I-beam members extending between and rigidly joined with the side beam members to form a rigid tubular body conforming gen upper flanges of the I-beam members forming a support for the fire box and the interior of the body communicating with and forming a downward continuation of the interior of the fire box, a refractory lining on the interior of the body between the upper and lower flanges of the beam members,'and legs secured to and extending downwardly from certain of said lower flanges to support the body.
