1 Claim.
At the present time, range boilers are made of steel plate and galvanized to protect them against corrosion. Such boilers, however, are subject to rusting and corrosion and are objectionable for that reason. Copper boilers have been used to a limited extent only because of their high costl and the relatively low strength thereof. Copper alloys have also been employed, but they are likewise very expensive.
Composite range boilers havegalso been suggested heretofore, suchas copper-lined steel tanks. These have been proved by experience to be neither cheap nor corrosion-resistant, and therefore, have not met the insistent demand for a cheap non-corroding range boiler. Enamellined steel boilershave also been proposed, but they are impractical and expensive from the standpoint of manufacture and easily damaged in shipment and use.
I have invented a range boiler or storage tank for domestic hot water systems which is highly resistant to corrosion and at the same time is relatively inexpensive to manufacture. In accordance with my invention, I provide a steel shell with a lining of substantial thickness composed of hydraulic cement. A lining of this character is practically non-corroding in the presence of hot water and effectively protects the steel shell from contact with the water. The shell also provides the strength necessary to resist the pressure of the water in the boiler. By making the lining thick enough, viz., greater than oneeighth of an inch, and preferably one-fourth of an inch thick, the lining'forms a strong arch in the shell which is highly resistant to damage which might otherwise result from handling in shipment and installation. The total cost of my range -boiler is not greatly above that of the ordinary galvanized steel tank.
A preferred embodiment of the invention with certain modifications is illustrated in the accompanying drawings. In the drawings:
Figure 1 is an axial section through a boiler or tank embodying/the invention;
Figure 2 is a/ transverse sectional view along the line II-II of Figure 1;
Figure 3 is a partial section corresponding to Figure 1, to enlarged scale;
Figure 4 is a partial section to enlarged scale showing the rst step of forming a modified pipe connection;
Figure 5 is a view similar to Figure 4 showing the next step; and
Figure 6 is a view similar to Figure 4- showing the complete pipe connection.
(ci. zzo-sa) Referring in detail to the drawings, the boiler or tank of my invention comprises a shell IU having a lining II. The shell I0 is composed of a cylindrical body portion I2, which may conveniently be formed by bending up fiat plate and welding the abutting edges thereof, as at I3. In addition to the body portion I2, the shell includes end closures Il and I5 having anges I6 overlying the ends of the cylindrical body I0 and Welded thereto as at I'I.
The lining II is composed of hydraulic or other suitable mineral cement and is preferably of a substantial thickness, viz., from one-eighth to one-fourth of an inch. The lining may be applied according to the method of my copending application Ser. No. 10,539 or otherwise, so long as it overlies substantially the entire interior surface of the cylindrical body I2 and the closure I 4. The thickness of the lining is uniform -throughout all portions of the boiler. By making the lining of substantial thickness, it forms a continuous arch which adds materially to the strength of the completed boiler. By using end closures which are convex, it is possible to obtain a substantially uniform thickness of lining throughout the interior of the tank.
Connecting sleeves I8 are provided for cold water supply, hot water delivery, and circulation to a heating coil. These sleeves penetrate the wall of the shell as well as the lining and are welded to the former as at I9.
In a modified form of the invention, portions of the connections themselves have a. protective cement lining applied thereto. As shown in Figures 4 through 6, connecting sleeves 20 are welded to the wall of the shell I0 in alignment with holes therethrough. During the formation of the lining II, plugs 2| are threaded into the sleeves 20. When the lining has set, the plugs are removed and holes drilled through the lining in alignment with the sleeves, as shown in Figure 5. The finished appearance of a connection formed in this manner is shown in Figure 6, from which it will appear that the inner end of the sleeve 20 is provided with a protective lining, as indicated at 22.
It will be apparent from Vthe foregoing description that the invention provides a range boiler or hot water tank characterized by numerous advantages over such tanks as previously used. The cement lining of the tank is practically incorrodible when subject to -the action of hot water and as the lining protects the steel shell from contact with the Water throughout, no corrosion thereof can occur. 'Ihe steel shell may be made of such thickness as to provide ample strength to resist the pressure of the water. The entire tank may be manufactured at a cost which makes it competitive with galvanized steel tanks, and for the first time, provides a satisfactory non-corroding hot water storage tank for domestic systems at a price considerably below that of copper or copper alloy tanks. i
As the term hydraulic cement" is used herein, it is used in its broad sense of a cement which requires water in hardening or setting, and which in general is capable of hardening under water. While I have illustrated and described herein but a preferred embodiment of the invention with a modification thereof, it will be understood that changes in the tank disclosed may be made without departing from the spirit of the invention or the scope of the appended claim.
