This invention relates to steam generators or water heaters of the kind comprising an annular water chamber having short closedended tubes or thimbles projecting radially inwards therefrom into a heating space through which hot gases pass. The object of the invention is to provide an improved generator or water heater of this type in which the path followed by the hot gases when flowing through the heating space may be improved and the amount' of heat transmitted from the hot gases to the water varied.
According to this invention a tubular member is mounted within the heating chamber with its wall adjacent to the ends of the thimbles, and the inlet passage for the hot gases at one end of the generator is so formed that a circular motion around the tubular member is imparted to the hot gases in addition to their longitudinal motion over the thimbles through the generator. To this end a substantially helical guide surface or passage for the hot gases is conveniently formed in a member at one end of the generator, the axis of the helix preferably being coincident with that of the generator .whereby the desired motion is imparted to the gases entering the central heating chamber of the generator.
Preferably a valve orthe like is provided -whereby part of the hot gases may be bypassed so as not to pass through that part of the central chamber in which the thimbles lie. One way of effecting this is to provide a two way valve in the delivery pipe.
for the hot gases exterior to the generator whereby the relative amounts of hot gases passing respectively through the generator and through a by-pass passage can be controlled.
In an alternative arrangement the tubular member may act as the by-pass passage, a valve being arranged to control therelative amount of the gases passing respectively through and around the tubular member. In this arrangement the tubular member may itself act as the valve andto this end may be longitudinally movable so as in one position to rest on a member which closes one of its ends so that all the hot gases are caused to pass through the surrounding space in which the thimbles lie, while in another position it closes communication between this space and the outlet passage and itself constitutes the only communicat- 1,637,681 PATENT OFFICE.

caused to pass. "The member on which the tubular member is adapted to rest when all the hot gases are to pass around it is conveniently conical while the gas outlet passage is coaxial with the tubular member and of such diameter that it forms a substantially gas-tight fit with the top of the tubular member when this member is raised. In this way the tubular member acts as a valve by means of which the relative amounts of the hot gases passing through it and through the annular space in which the thimbles lie can be varied as desired.
The invention may be carried out in various ways but two alternative constructions according to this invention are illustrated somewhat diagrammatically by way of example in the accompanying drawings, in which Figure 1 is a vertical section alon the longitudinal axis of one construction 0 generator in which a separate byass valve is provided to vary the amount 0 gas passing thrpugh the heating space of the generator, an
Figure 2 is a similar view of an alternative construction in which the tubular member itself acts both as a by-pass passage through which part of the hot gases may be caused to flow and a valve for controlling the relative quantities of the hot gases flowing respectively therethrou h and through the space in which the thim les lie.
In the construction illustrated in Figure 1 the generator or water heater comprises a substantially annular water chamber built up from two coaxial cylindrical members A and B connected by suitable plates C and C at their upper and lower ends. The inner. member B carries a series of short closed-ended tubes or thimbles D projecting radially inwards therefrom, into a central space through which the hot gases are adapted to pass and is somewhat reduced at its upper end as shown at B to form an outlet passage for these gases.
The-annular water chamber is supported on a base E which conveniently has a lining F of refractor material and contains a pluglike member Gi also preferably of refractory material, in which is formed a substantially helical inlet passage G for the hot gases, this passage communicating with a delivery pipe H and also preferably having'a liquid fuel burner indicated at H disposed therein. The helical passage causes the gases to circulate round the central space as they pass through it. The member G has a hollow central boss G adapted to accomodate a plug J on the lower end of a tubular member J mounted in the central space of the generator and of such diameter that its wall lies adjacent to the inner ends of the thimbles D. The tubular member J comprises a lower portion J 2 formed of refractory material and an upper portion J formed of metal. The lower end of the upper portion J fits over the upper end of the lower portion J and is connected thereto by one or more pins or the like J The upper end of the tubular 7 member J is formed conical and supported by a vertical bolt K, one end of which engages a suitably tapered plug J 5 in the upper end of the member J while the other end engages a bridge piece K extending across the upper end of the outlet passage 13.
The delivery pipe H conveniently communicates with a bypass passage H and interconnected valves LL are provided controlling respectively the passages H and H and adapted to be operated simultaneously by a lever L so as to vary the relative quantities of the hot gases flowing respectively through the generator or water heater and through the by-pass passage H These valves are so interconnected and arranged that when one is fully open the other is fully closed as shown.
A cylindrical bafile M is conveniently disposed in the water space so as to extend around substantially the whole of that portion of the inner cylindrical member B in which the thimbles D are disposed and thus assist in the circulation of water which will tend to pass up inside the baflle and down outside it. When the apparatus is intended for use as a stem generator a perforated steam collecting pipe N is conveniently disposed in the upper end of the steam and water space as shown.
In the construction illustrated in Figure 2 the steam generator and water heater comprises an annularhwater space built up from two cylindrical'members O P connected by suitable flanges or the like at their, upperand lower ends. The inner memb'enP carries a series of short closed-ended water tubes or thimbles Q projecting radially inwards helical passage causes the hot gases to. circulate round the central space as they pass,
the helical passage R are caused to flow through the annular space in which thethimbles Q lie. When the tubular member is raised however its lower end is opened and in its fully raised position its upper end fits within the outlet passage P as shown in dotted lines in the drawing. In this position it will be seen that communication be tween th annular space in which the thimbles Q lie and the outlet P is cutoff so that all the hot gases are caused to flow through the tubular member S. In its intermediate position some'of the hot gases pass through the tubular member S and some through the space surrounding it, the relative quantities of hot gases passing through and around the tubular member depending on its position. The tubular member S may be raised and lowered in any suitable way but is conveniently operated by a link S connected to a lifting eye S on the upper end of the tubular member. The lower end of the tu- 'bular member S is convenently steadied when in its raised or an intermediate position by means of a guide member comprising a vertical pin S mounted on the member T and carryin a member S having three radial plates 5 the outer edges of which freely en.- gage the interior of the lower end of the tubular member S and thus act as a guide to steady this member when it is not resting on the conical member T.
As in the construction shown in Figure 1 a cylindrical baffle plate Uis conveniently provided in the annular water space extending around that pprtion of the inner cylindrical member carrying the thimbles, this battle serving to assist the circulation of the water which tends to flow up inside the baffle and down outside it.
In either of the constructions illustrated, where a liquid fuel burner is provided in the helical gas inlet passage, this burner is conveniently disposed so that the hot gases therefrom flow along the helical passage into the central space and may be employed either to supplement the hot gases normally supplied or instead of' them.
The apparatus is particularly adapted for utilizing the exhaust gases from a Diesel or other internal combustion engine to generate steam or heat water and, in this case, the liquid fuel burner may be used to supply to secure by Letters Patent is:-
