STEAM GENERATOR 0R WATER HEATER.
y Application led January 23, 1924, SerialNo. 688,036, and in Great Britain February 1li 1923.-
vThis invention relates to steam generators or water heaters and has for its object to provide a enerator or water heater of simple but e cient construction which is intended more particularly to be heated by gases such as the waste or exhaust gases roma prime mover or other source.
A further object is to provide a steam generator or water heater, to be employed more especially in this way, which will bev cheap and simple in constructionso that it can be readily dismantled and cleaned whileeconomy while providing steam for usefulv Work or maintaining 'a .hot water supply by utilization of the heat from otherwise waste gases.
Further objects ofthe invention will be seen from the embodiments of the invention illustrated by way of example in the accompanying drawings, in which Figure 1 is a sectional elevation of a steam generator construction arranged for the hot,- gases to enter and leave at the up-.ey per end of the generator. s
Figure 2 is a ysection on the line 2-2 of Fi ure 1. 4 Y
igure 3 is a. sectional elevation of an alternative construction of steam generator in which the hot gases enter and leave at the bottom.
.In the construction illustrated in- Fi res 1 and 2, the outer member or shell o the generator is constituted by a c linder A of suitable length one end A o Ywhich. is closed permanently so that this end of the cylinder is integra with the wall of thecylinder the endA being, for example, p roduced by pressirgor a like rocess. Around the o en end o the cylin er A isa liange A2 o vsuitable width while in the centre of the closed end A is a small opening provided with-a cock B which enables mud and sediment to be removed, the end A of the cylinder bein-g so contoured that thismaber1al will accumulate in the neighbourhood of the opening and thus facilitate cleaning. The cylinder Ais mounted verticall on a suitable base by means of brackets The inner member of the generator is constituted by a cylinder D with one end D closed and formed integral with the cylindrical wall thereof, the end D being formed by pressin or otherwise in a manner similar to the ormation of the end A of the outer e cylinder A.Y As shown, the, inner cylinderv D has a diameter appreciably less'than the' outer c linder A by means of bolts or the like he inner cylinder D is thus supportedby lits 'iiange D2 concentrically within the outer cylinder A with the closed end D of .the inner cylinder separated tromtheclosed end A of the outer cylinder by a' distance substantially equal to the distace'betwen fthe cylindr1cal walls of the two cylinders.-
In the wall of the inner `cylinder D therel is fixed a series of thimbles F each thimble beingjformed, for example, by pressing so that it is integral throughout and has a sli ht ta en so that its rounded and closed en is o less diameter than the open vend of which is fixed insome. suitable manner in the wall of the cylinder D. In practicea it is found vsullicient' to insert each thimble in an openin in the cylinder and press or hammer the t imble into lace any expanding process or screwthreasing being unnecessary since, in the case of a steam enerator, the pressure within the thimbles 1s always in a direction tending to keep them in place gliv and maintain tight 'oints between the thimbles and the cylin er wall. The 'thimbles are constructed and arranged in 'a manner substantially similar to that described and illustrated in the specification and drawp ings-of the present inventors British Letters Patent No, 108,177, the thimbles pro'ecting radially inwards from the wall of t e cylinder D and their open ends communicating with the steam and water space E between the cylinders A and D. The 'thimblesare disposed in that ortion of the wall of the inner cylinder which lies at and below the normal water level in the generator. K,
A cap G conveniently' somewhat conical the cap G having a flange G which rests' closes the open end of the inner cylinder D `central opening G2 in the cap G whence they pass down the tube H. Facing the inner end of the tube H and secured on the inner side of the closed end D of the cylinv der D is a conical deflector J of rebrick or other suitable material adapted to deflect the hot gases flowing from the tube 'H so that they traverser the spaces between the thimbles F before passing upwards around the tube H into the cap G whence they escape through the opening G3 and pipe G4@ In this way the hot gases circulate thoroughly throughout the interior of the cylinlder D and give up a substantial portion of their heat to the water in the thimbles F and water space E. i
Water is delivered into lthe space E through the outer cylinder A by means of a feed water pipe K communicating with the space E at a suitable point, and it is convenient to dispose a light metal and cylindrical shield L in the water space E between.
the inner and outer cylinders so that as the feed water enters it will becaused to flow downwards-and upwards and around the water space and not directly on to the inner cylinder D or into the thimbles F opposite the inlet from the pipe K. The shield L is so mounted on studs L as to permit it to expand or contract freely relatively to the cylinders A and D. The cylinder A is preferably provided with suitable lagging M. The delivery of feed water to the generator may be controlled automatically as for instance by a float operated device N such as described and illustrated in `the specication and drawings of the present inventors Letters Patent of the United States of America No. 1,350,988 or alternatively by a thermostatic or pressure actuated device.
A steam outlet controlled by a valve O isl provided in the cylinder A at the upper end of the space E.
In the steam generator illustrated in Figure 3, the construction is similar to that shown in Figures 1 and 2, the whole apparatus, however, being inverted.
In this case the cylinders A and D are mounted with their open ends downwards and the member Dis made slightly shorter so as to leave a larger space between the closed ends A and D of the two cylinders,
mames the drain cock B being disposed at the bottom ofthe annular space between the cylinders and passing through the anges G and D2 to permit the removal of mnd and sediment from the space E. Further, the feed water pipe K and metal shield L are arranged so vthat the feed water is delivered at the correct position in the height of the generator. The steam outlet valve O in this construction is conveniently disposed in the centre of the closed end A of the cylinder ,A and thedevice N for controlling the feed water supply is positioned according to the water level. In this construction it is conveniently arranged for the hot gases toenter through the lateral opening G3 in the cap G the gases then flowing upwardsbver the thimbles'F and flowing out through the pipe H. The other parts of the steam generator or water heater are arranged in a similar manner to that described with reference to Figures 1 and 2.
