FLQMAN Y SUBMERGED WATER HEATING COIL Filed Jung 26, 1955 INVENTOR V/cbr Fe/alnan BY Patented Apr. 20, 1937 UNITED STATES PATENT OFFICE.
Application June 26,
3 Claims.
This invention relates to new and useful improvements in a submerged water heater.
The invention has for an object the construction of a submerged water heater which is characterized by a boiler having a longitudinal water compartment through which the fire tubes extend longitudinally, and water heating tubes mounted on one side of the boiler and extending into the Water space obliquely of the side walls of the boiler and upwardly inclined with respect to the horizontal, The advantage of this construction Will become readily apparent by considering prior devices.
It has been customary to construct submerged water heaters which are extended in from the front of a boiler. This is a very eicient type since the water tubes may then extend the full length of the water compartment of the boiler. However, very often it cannot be installed as an attachment on boilers as the fronts have no spare space which may be utilized. Consequently, numerous other types of submerged water heaters have been constructed to be used in various ways.
A generally used type of submerged Water heater is one in which an auxiliary tank is mounted adjacent the boiler and the Water from the boiler connected with the tank. The Water heating tubes are then mounted within the water of the tank. This method is undesirable for several rea- 0 sons, namely, it requires an auxiliary tank and the circulation between the water in the tank and the boiler being poor. Some installations therefore utilize a circulating system which adds to the expense.
Another type of submerged boiler is the arrangement of an auxiliary hollow member which is attached on the side of the boiler and lengthens the operative Width of the boiler at this area. It is then possible to insert the water heating tubes in this auxiliary member and into the boiler.
If the tubes were inserted transversely into the boiler without the auxiliary member, there would not be sufficient heating area. of the tubes to operate properly. Ihe disadvantage of this type of water heater resides in the fact that the hollow member which is attached on the side is unsightly and quite large, and very often the location of the boiler is such that there is no room for the member. I
It is applicants concept to engage the heating tubes into the side of the boiler, but obliquely and upwardly inclined with respect to the horizontal, so that they are comparatively long and at the same time all need of an auxiliary tank or projecting extension member has been eliminated.
1935, serial No. 28,405
Another object of the invention is the construction of a device as described which is simple and durable and which may be manufactured and sold at a reasonable cost.
For further comprehension of the invention and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.
In the accompanying drawing forming a material part of this disclosure:-
Fig. 1 is a perspective view of a boiler with a. submerged water heater constructed according to this invention.
Fig. 2 is a side elevational view of the water heater, per se. Y
Fig. 3 is an edge elevational view of Fig. 2 looking in the direction of the line 3-3 of Fig. 2.
Fig. 4 is an end elevational view looking in the direction of the line 4-4 of Fig. 2.
Fig. 5 is a sectional view taken on the line 5-5 of Fig. 2.
Fig. 6 is a fragmentary plan view of a portion of Fig. 1.
Fig. 7 is a view similar to Fig. 6 but illustrating another embodiment of the invention.
The submerged water heater, according to this invention, is used in combination with a. conventional boiler I0 which has a longitudinal water compartment I I in which the re tubes I2 extend longitudinally. 'I'he submerged water heater comprises water heating bent tubes I3 mounted through the side of the boiler and extending into the Water space obliquely of the side wall and upwardly inclined with respect to the horizontal. To facilitate the mounting and installation of the Water tubes, a water inlet and outlet member I4 and suppo-rt I4' therefore is secured in an opening formed in the side of the boiler. 'I'his water inlet and outlet member has an inlet I4 terminating in a plurality of small openings I5 in which one of the ends I3a of one group of the tubes I3 engage. I'he other ends I3b of this group of tubes I3 connect with certain openings I4b in a central compartment |42 in the member I4. Another group of tubes I3 have their ends I3c connecting with the remainder of the openings I4". The other ends of the tubes I3 of this group connect with other openings I 4d in the outlet portion I4 of the member I 4. The construction is such that water enters the inlet I4a, circulates through one group of the tubes I 3, then circulates through the compartment |46, through the other groups of tubes I3, and finally discharges from the outlet I4".
The member I4 is attached upon a support member I4' by several bolts I6 which engage through lugs I1 on flanges of these parts. The member I4 is tubular and engaged into an opening I8 in a side wall of the furnace, and is welded in position to make a, waterproof joint.
In Fig. 7 another embodiment of the invention has been disclosed which is very similar to the prior form except for the fact that there is a support member I4 upon which the water inlet and outlet member I4 is mounted. This member I4 is solid (not tubular) except for the fact that it is formed with a plurality of passages |42. The tubes I3 are connected directly with the inner ends of these passages. The support member I4" also has passages I4z connecting with the compartment |40. The object of this construction is to eliminate the extension of the tubes I3 into the hollow of the member I4. The advantage gained is that the construction will be much stronger in that the projecting part from the boiler is solid instead of hollow. The support member I4" has a base flange 14X which is Welded on the side of the boiler over the opening I8. Several studs MY aremounted on the flange I4x and pass through anges upon the outer end of the support member I4 and the member I4. Nuts I4W are mounted upon the studs I4Y and serve to hold the member I4 in position.
The operation of the device is v-ery similar to priorsubmerged water heaters, except for the fact that because the tubes I3 are arranged obliquelyy and upwardly inclined with respect to the horizontal, they may be relatively long, much longer than the width of the boiler though not as long as the length of the boiler, and at the same time they are mounted upon the side of the boiler.'-v
By having the tubes inclined upwardly with respect to the horizontal plane of the boiler so that they pass above the fire tubes, additional length is achieved over tubes parallel to the horizontal plane.
While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:-
1. In combination, a boiler having a longitudinal water compartment through which re tubes extend longitudinally, a water inlet and outlet member mounted obliquely upon and extended obliquely through an opening in one of said side walls, and water heating tubes mounted on said member and connected with said inlet and outlet and extending into said water space obliquely to said side wall and upwardly inclined with respect to the horizontal.
2. In combination, a boiler having a longitudinal water compartment through which i'lre tubes extend longitudinally, a water inlet and outlet member mounted on and extending obliquely through an opening in one of said side walls, and
water heating tubes mounted on said member and connected with said inlet and outlet and extending into said water space obliquely to said side wall and upwardly inclined with respect to the horizontal.
3. In combination, a boiler having a longitudinal water compartment through which I'lre tubes extend longitudinally, a water inlet and outlet member mounted obliquely upon and extended obliquely through an opening in one of said side walls, and water heating tubes mounted on said member and connected with said inlet and outlet and extending into said water space obliquely to said side wall and upwardly inclined with respect to the horizontal, said member being supported on a tubular member welded upon the side of the boiler and in an opening in the side wall.
