The boiler illustrated comprises a plurality of upper transverse steam and water drums, here shown as three in number, and including a front drum 10, a middle drum 11 and a rear drum 121 The n per steam and d by respective drum 26. The front drum is connected to the middle drum by water circulators 16 and steam circulators 17, while the middle drum 11 is connected by steam circulators 18 to the rear drum 12. Certain tubes in the bank 15 are connected at their upper ends to the middle drum 11, thus forming a connection through the tubes and mud drum between the drums 11 and 12. The drums 10, "11 and 12 are therefore connected both above and below the normal Water line so that pressure may be approximately equalized.
In the illustrated embodiment of my invention, the means for preventing priming in the boiler comprises a vessel 19 located in one of the upper steam and water drums and preferably within the middle drum below the steam outlet connections to the circulators 18. The vessel 19 is preferably open at its top and with the upper edge preferably sub stantially horizontal, the vessel being located at the highest desired water level in the drum 11 The vessel 19 is supported from r the drum by a suitable number of brackets 20 extending to the drum, one edge of the vessel preferably being separately supported from the drum as at 21. The essel which is preferably oblong in form extends longitudinally of the drum, and preferably extends substan- "animal and Kay is,

The connet'tfom22' also preierably includes a means for utilizing the heat in the water blown from thefdrum, and in the form illustrated, comprisesw heat ransfendevice 23: in the form of -aivesselito DAVFDEK mes--01 crn, new am-say, s ams a v. wr noox' comm,-or nayom, mew amnm acoaroaanon or nnw' g l whichthe :pipe 22 is. connected: and from whichethe connection 22' .leads, the: feed" pipe 24, which leads to the meal:- dsmht=12 passin through ,the, vessel 23" and 1 being aprovide Vtilth'ilZ CQll25 located therein, in order efiective ly to transfento the .ifeed water, the heatremthe W r: blown. efrointhe-drum. i
It is well understood that in the operation ofa boiler, over-concentrationio-f solids'i'n the boiler results 1in; priming; ,Wheii overconcentration occurs;--the; water arises in the drums :In, the; type rot; boiler; shown, the
front-bank Qfr'tubes 13%ia the one-which is xposed to the hottest ga'sesiandthe bank 15 is exposed to thesame gases after'they have become cooled. Any intermediate-banks such as the bank 14, are subjected to the gases at an intermediate stage,-as regards-their temperature. The result; isthat-Zthe dense'stwater is inlthe bank 15-and ill'zth steam and water drum-12; and theswaterzinithe banks 14 and; 13 is progressi-vely; less dense as is well. known inrthearta Therefore, the level of waterin thfigiIjODtgd-IUll'lilS higherithan in the middle and reap-drums and: that zin the middle drnm ishig-hen than in the rear drum. If this wa ter reachestoohigha level, it will be forced over through. the steam cireulators into the aneatadrumto the rear and if; forced int-o the rear drum-12 may decreasethe density ofthewaterin that drum and in the rear bank-of tubes 15 to such a degree that the water in -gthe rear, drum will rise to such an extent as to cause. priming. ThIisis particularly the case with impure waterf having a high concentration. WVhen a Stirling boiler is equipped with the described automatic blow-off device, with the vessel included in the blow-off device located in the intermediate or rear upper steam and water drum, then when the water, because of the concentration and the resulting rise in level, reaches the top of the vessel 19, water is automatically blown from the vessel and from the drum, thereby preventing the water rising above the top of the vessel and, in turn, preventing over concentration of solids in the water and resultin priming.
n Fig. 2, I have illustrated a modification wherein the vessel 19 is applied to the rear steam and water drum instead of the intermediate drum as in Fig. 1, it being under stood, of course, that the parts to which the ipe 22 is eolnecte'cl are the same as those illustrated in Fig. 1.
By the heat transfer device which I preferably provide, the heat in the water thus blown off, may be returned to the system.
While I have illustrated my invention in connection with a Stirling boiler, it will be understood that its use is not limited to this type of boiler. Furthermore, the embodiment may be widely varied.
I claim:
1. In a boiler, a plurality of steam and water drums, tubes connecting each of said drums to a lower water drum, connections between said drums above and below the normal water levels therein, a steam outlet on one of said drums, and means in one of the other drums to prevent the level of water in said first drum rising sufiiciently'to cause priming.
2. In a boiler a plurality of steam and water drums, tubes connecting each of said drums to a lower water drum, connections between said drums above and below the nor mal water levels therein, a steam outlet on one of said drums, and means in one of said drums to prevent the level of water in said first drum rising sufficiently to cause priming.
3. In a boiler, a plurality of steam and water drums, tubes connecting each of said drums to a lower water drum, connections between said drums above and below the normal water levels therein, a steam outlet on one of said drums, and means preventing discharge of water from the other drums into the drum from which steam is taken.
4. In a boiler, a plurality of steam and water drums, tubes connecting each of said drums to a lower water drum, connections between said drums above and below the normal water levels therein, a steam outlet on one of said drums, and means for reventing primin by preventing the have? of water in one of the other drums from rising beyond a certain predetermined level.
5. In a boiler, a plurality of steam and water drums, tubes connecting each of said drums to a lower water drum, connections between said drums above and below the normal water levels therein, a steam outlet on one of said drums, and means for preventing priming by preventing the level of water in one of said drums from rising beyond a certain predetermined level.
6. In a boiler, a plurality of steam and water drums, tubes connecting each of said drums to a lower water drum, connections between said drums above and below the normal water levels therein, a steam outlet on one of said drums, and means to prevent priming by preventing substantial decrease of the 'density of the water in the drum having the steam outlet. x y
7. In a boiler. a pair of steam and water drums, tubes connecting each of said drums to a lower water drum, connections between said drums above and below the normal water levels therein, a steam outlet on one of said drums, and a blow-down device disposed in one of said drums and constructed and arranged to maintain the level of water therein below a predetermined high point.
