June 3, 1941. F. o. A. OHLSSON- VERTICAL HOT WATER BOILER Filed June 50, 1939 2 Sheets-Sheet 2 Fig. 2.
Patented June 3, 1941 UNITED STATES PATENT FFICE Application June 30, 1939, Serial No. 282,297 In Sweden July 2, 1938 3 Claims.
The present invention relates to a hot Water boiler of the kind that has a firebox, a combustion chamber for the flue gases sparated from the firebox by means of a substantially vertical wall and a hot water supplier provided in the Water space.
The invention is substantially characterised thereby that the partition wall consists of a number of substantially vertical tubes, which communicate, at their lower ends, with an intake for the feed water and, at their upper ends, with the water space, and that each of the inlet pipes of the hot water supplier is drawn through a. tube (or some of the tubes) for the purpose of effectively heating the incoming feed water and protecting the inlet pipes for the hot water supplier.
The invention is also characterised by the fact that the outlet from the boiler to the radiators is provided either somewhat above the roof of the firebox or in the top of the boiler, said top being located higher than the roof of the firebox, and that the inlet from the return pipe to the boiler is provided at the bottom of the same or connected to a larger inlet pipe communicating with the tubes.
One embodiment of the invention is illustrated on the accompanying drawings. Fig. 1 shows a vertical section through the middle of the boiler and perpendicularly to the partition wall between the firebox and the combustion chamber for the flue gases. Fig. 2 shows a vertical section through the middle of the tubes in the partition wall. Fig. 3 is a horizontal section on the line III-III in Fig. 2.
Reference numeral 2 indicates the outer shell of the boiler and 3 the inner shell of the same. Both these shells are cylindrical and located substantially concentrically relatively to each other. The firebox is indicated by 4 and the combustion chamber for the flue gases by 5. The supply opening for the fuel is indicated by 6 and the slag and cleaning opening by I. 8 is the ash pit and 9 the ash pit damper. The water is returned to the boiler through a substantially horizontal inlet pipe In, which is connected to the water pipe. From this pipe there emanates a series of vertical tubes H, which together form a circulating battery for the water and a partition wall between the firebox 4 and the combustion chamber for the flue gases. The tubes open into a pocket l2, which in turn opens into a cylindrical portion l3, which is connected to the curved firebox roof M, which merges in the roof of the combustion chamber for the flue gases at l5. The firebox roof has been given this curved shape to most effectively resist the stresses to which it will be subjected according to load. The roof of the firebox formstogether with the roof of the pocket and the cylinders 3 and i3 openings I6 between the firebox and the combustion chamber for the flue gases, through which openings the flue gases pass on their way to the flue gas outlet ll via an ash pocket l8. In the outer shell somewhat above the roof of the firebox there is provided an outlet IQ for connection to the heating bodies or radiators, which are located above the bottom level of the boiler. At the bottom of the boiler there is provided an inlet 20 for the return pipe. If a radiator should be located beneath this level there is provided an outlet 2! in the top of the boiler and an inlet which is coupled to a connection at the bottom of the boiler. Hereby a vivid circulation of the hot water is created, the hot water flowing to the top of the boiler and therefrom through the pipe to the radiators, passing the radiators and from the lowest radiator through the return pipe to the inlet ID in the circulating battery of the boiler. V
The hot water supplier consists of pipe coils provided in the water space. The drawings show two vertical coils 22 and 22a, each lower part of which merges in a straight pipe 23. These pipes are drawn through the tubes of the circulating battery, through the inlet pipe Ill and connected to the water pipe 24. The pipe coils are united to a common outlet 25 to the hot water pipe at the top of the boiler. The lower portion of the hot water supplier extends down into the cylindrical portion l3 towards the pocket I2, the drawing of the straight pipe portions through the circulating battery being thereby facilitated. Reference numeral 26 indicates a connection to the expansion pipe.
The boiler functions as follows:
The boiler and the radiators are filled with feed water in usual manner whereafter heating takes place. The boiler operates as a usual combustion boiler, the flue gases sweeping over the upper portions of the circulating battery and the firebox and then leaving through the openings IE to the combustion chamber 5 for the flue gases. Owing to this arrangement a large contacting surface for the heat emission of the gases is obtained and, owing to the high temperature of the gases, a very rapid circulating motion of the water in the battery. The water,- therefore, rises through the pipes of the battery, through the collecting pocket and the cylindrical portion to the upper part of the boiler, wherefrom it is led to the radiators either through the outlet it! or the outlet 2| and is returned to the boiler through the return pipe, which is connected to the inlet 28 or to the circulating battery.
The hot water supply takes place in such a way that cold water is supplied from the water pipe 24 to the inlet pipes 23 of the battery. The water is then subjected to the high temperature of the circulating battery so that a considerable preheating of the same takes place. When the hot water has reached the top of the boiler, it has also reached its highest temperature.
The invention is, of course, not restricted to the shown embodiment but the various details may be varied in many ways without going beyond the scope of the invention. Thus, for instance, the horizontal section of the boiler must not be circular but any suitable shape may be used. The circulating battery may also be changed in such a manner that there are more or less tubes than shown on' the drawings. The number of coils in the hot water supplier may also be varied.
Having now described my invention, what I claim as new and desire to secure by Letters Patent is:
1. A hot water boiler comprising inner and outer Walls providing a water space therebetween, a water intake for the water space, a plurality of water tubes communicating at their lower ends with the water intake and at their upper ends with the water space, said tubes forming a substantially vertical partition within the space enclosed by the inner wall and dividing said space into a combustion chamber and a fire box, a water heater located in the water space, and inlet pipes for said water heater extending through said tubes for efiectively heating the water passing to the water heater and for protecting said inlet pipes.
2. A boiler as claimed in claim 1 characterized by provision of a water outlet for said water space located somewhat above the top of the fire box, and an additional water intake communicating with the water space at the bottom of'the fire box.
3. A hot water heater as claimed in claim 1 characterized by the provision of a water outlet communicating with the water space at the top of the latter above the top of the fire box, said intake being adapted to be connected with the water return.
