This invention relates to a water tube steam i boiler in which thesteam is generated by the latent heat of condensation of the vapor of a high boiling point` liquid. The generating surfaces ofthe steam boiler are enclosed into a cylindrical shell into which the vapors are introduced and condensed.
An object ot theinvention is to provide a steam boiler wherein the steam generating surface or heat absorbing unitis heatedby a vapor from a high boiling point liquid, and in which, by reason ot' the differences in temperature betweenthe respect-ive parts, itis essent-iai to adequately care for the relative eX- pansioii and contraction of the composite arts.`
A further feature resides in the .particular construction of such a boiler as is mentioned iii the preceding paragraph, and wherein an exterior vapor receiving andcondensing shell houses the major portion of a steam generating or heat absorbingunit for converting wateriiito steam. and in which combination the 'parts are so arranged that the connections to the heat absorbing unit may be entirely outside the vapor containing shell. thereby' eliniinating man v joints which would otherwise have to be iliade vapor-tight; and, also, so mounting the heat absorbing unit with respect to the shell that it may expand and contract both longitudinally and transversely1 wit-hout disarrangiiig the parts or producing vapor leaks.
The invention will be understood from the description in connection with the accompanyingl drawings in which Fig. 1 is a vertical section through an illustrative embodiment of the invention: Fig. 2 is a section partlv broken away along the line 2-2 ot Fig. l; Fig, 3 is a section showing one of the details. Fig. 4 is a section along the line 1f-4t ot Fig. 1; and Fig. 5 is a similar section through a modification.
In the drawings reference character 1 indicates a easing or cylindrical shell that is provided with an inlet 2 at one end thereof for iiiercuiy vapors. An outlet 3 for condensed mercury is provided at the bottom.
The shell 1 is supported upon supports 4 near opposite ends and an upper drum ex- 1928. Serial No. 294,957.
tends into the shell through one end and prajccts to some distance outside ot the shell. Si. similar lower drum 6 smaller than the drum 5 is also provided and extends through the same end of the shell 1. L valved drain pipe 7 may be provided at the bottoni of the drinn 6 outside of the shell 1. A- feed pipe E enters the end of the upper drum 5 that extends outside ot the shell 1 and the feed pipe S extends substantially entirely through the drinn 5 and is supported upon cross supports 9 at intervals. A. water level indicator 10 and satety valve connections 11 are provided on the portion ot'v the drum 5 that extends outside of the shell. A dry pipe 12 supported by straps 13 is located in the upper or steam space of the drum 5 and the outlet 14 from this dry pipe extends through the upper surface of the extending end of the drum 5.
Rows ot' bent tubes 15 connect the drums 5 and 6 on the inside otl the casing 1 and the ends of these tubes enter both drums radially. The upper drum 5 is supported upon cross supports 16 and the lower drum t3 is supported from the drum 5 by means of the tubes `15 and is treeY to move up and down when the tubes contract and expand. A flexible seal 17 is provided between each drum 5 and 6 and the casing lwhere the drums pass through the casing. A portion of the seal 17 is shown in Fig. 3 on aii enlarged scale. The seals 1T are between the parts, namely, the drums 5 and 6 which are in contact with the water or steam on one side and vapor on the other side and the shell 1 which is in contact withvapor only, so that difference in expansion between them may take place without causing leakage, that is, there are flexible seals between the. steam. boiler and the vapor condenser shell. The mercury vapor shell 1 can in crease iii diameter in' starting up with cold water in the drums 5 and 6 without causing leakage to take place due to diii'erenee in eE- pansion.
In the modification shown in Fig. 5, only one drum, namely, the steam and water drum 5 extends into the casing 1 and a portion of this drum on one. side of a vertical plane through the drinn is connected rows of curved tubes 15 to a similar portion or". the.
tit)
drum upon the other side of the plane, the ends of the tubes entering the drum on radial lines.
The operation is as follows: Feed Water is supplied through the feed pipe S, which may be provided with distributed openings in the drum 6, and the drum 5 is liept about half filled with water which also fills the tubes and the drum 6. Vapor-s ot a high boiling point liquid are introduced into the casing 1 through the inlet 2 and condensing around the tubes 15 andthe drums give up heat which generates steam from the Water in the drums 5 and 6 and tubes 15. The condensed vapor passes out through the outlet 3. The steam collects in the steam space of the upper drum and passes out through the dry pipe 12 and outlet 14 to the place of use.
