This invention relates to superheaters, and particularly to superheaters used in connection with a stationary boiler having vertical fire tubes and a smoke box disposed above the fire tubes wherein the superheater is disposed.
The general object of my invention is to provide a superheater for vertical or station ary boilers which will take steam from the highest point of the boiler, pass the steam through a double coil so that the steam will be completely re-heated, and then take the steam directly to the engine or cylinders thereof.
A further object is to provide a double superheating coil of this character which will not interfere with the draft and which is located or placed close to the top of the fire tubes or fines where the coils will get the benefit of the greatest heat.
A still further object is to provide a superheater of this character which may be applied to any boiler without changes therein.
My invention is illustrated in the accompanying drawings wherein Figure 1 is a vertical sectional view of a stationary boiler having my improved superheater applied thereto;
Figure 2 is a section on the line 2-2 of Figure 1;
Figure 3 is a fragmentary detail section through one of the fire tubes and the supporting leg;
Referring to the drawings, 10 desiginates the outer shell of the boiler having the head 11 and the smoke box 12, this smoke box having an upwardly and inwardly inclined wall, designated 13. The bottom of the smoke box is formed by the sheet 14 through which the fire tubes or flues extend. So far I have described an ordinary stationary boiler.
Disposed within the smoke box 12 and in the lower portion of the smoke box are two coils of pipe, designated 16 and 17. These coils are disposed concentrically to each Disposed upon the head 11 is a T 18 which takes steam from the boiler at the top thereof and this T is connected by the L 19 and unions 20 to the pipes 21 and 22. The pipe 21 extends into the inner coil 17, this pipe 21 extending downward and connecting Serial No. 219,320.
to the lowest coil of the series of coils 17. The coil 17 at its upper end extends tangentially outward, as at 23, and connects by a union 24 and L 25 to a T 26, which in turn connects to a pipe 27 leading to the cylinders of the engine. The pipe 22 likewise extends clownward and connects with the outer coil 16, and the upper end of this coil 16 is connected by an elbow and nipple to the union 28, which in turn connects with the T 26.
It will be understood, of course, that any usual or suitable pipe fittings may be used for connecting both coils to the T 18 and connecting both of these coils to the T 26 and pipe 27. The two coils are supported upon a triangular frame, designated 29, having feet 30 which are constituted by short flue nipples driven into certain of the fines 15. The supporting frame is preferably welded at the corners. The coils are made preferably of one-inch extra heavy pipe, though obviously other pipe may be used.
It will be seen that by this construction the boiler is tapped out and the steam taken from the highest point and this steam is heated in a plurality of coils so disposed as to receive the maximum heat from the boiler, that is the heat which passes out through the fire tubes into the smoke box 12. It will be seen that this double coil is so arranged that it will not interfere with the draft. In actual practice I find that with my superheater applied to a boiler ordinarily carrying 100 pounds of pressure, the boiler pressure can be cut down to about or pounds and deliver the steam to the engine or cylinders at a pressure of approximately 127 pounds and the steam will be practially dry. This use of dry steam prolongs the life of cylinder, valve packing and the pistons and eliminates the wear and tear on machinery caused by the engine working water or using saturated steam. In any steam heating plant this superheater may be used and it will deliver dry steam to the radiators, eliminating most of the dampness caused by the use of ordinary saturated steam, saving fuel and otherwise economiz-- ing. This superheater may be used on all boilers except those used on locomotives, steamships or steam-drlven automobiles.
