CLASS 36: heating systems.

In the present invention, the installation of a circulation boiler, its arrangement and to regard the type of connection with a heating boiler as new and peculiar.

The purpose of this innovation is to ensure vigorous circulation and rapid heating, as long as possible, even after the fire has gone out, in boilers for low-pressure water heating achieve.

The drawing shows an outline, the circulation boiler A being drawn in longitudinal section and the heating boiler B being drawn in elevation.

The former is built on the cylindrical furnace chamber formed above the fire grate and protrudes with its freely hanging Field'sehen boiler tubes α and / or. α ¹ into the room C , so that this and the floor of the circulation boiler A are washed by the combustion gases.

The Siederöhren are installed so that inner ^a1 direct DAF in the boiler room A open out, whereas the outward α by means of extensions b ^l passed through this boiler room and b merge into a positioned above the upper boiler bottom collection fitting, which direct to the to the radiators leading main pipe c is connected.

The boiler B is used to store a larger amount of heat and is walled in in such a way that the heating gases flowing from the furnace C wash around it on all sides before they are discharged through the chimney.

The connection of these two boilers with each other and with the radiators is carried out by pipes that are always open, without any kind of valves, of which a main pipe d serves as a return line for the water from the radiators. The same divides just before the boiler B into two lines, one of which is d ^[and which leads into the heat boiler B other if ² in the boiler room A.

The leading to the radiators main pipe C passes from the upper space b from the vessel A and is connected to the heat boiler B through a conduit c ¹ is connected.

The mode of operation of the boiler and the circulation of the water is therefore as follows:

The water flowing back from the radiators through pipe d passes through pipe d ² respectively. d ¹ . into boilers A and B. In the circulation ^{boiler 1 it} runs along the inner tubes a 1 of the Field's tubes and rises up the outer tubes α , whereupon it warms up more and more and finally, partly transformed into steam, passes through the connecting stubs b ¹ into the collecting stub b and from there the radiators flow through the main pipe c. The water, which is gradually heated in the boiler B , rises through the pipe c ^l and mixes with that in the main supply pipe c.

In this way a constant and very lively circulation of the water is achieved.

As a result of the arrangement of the tiles, pipes can be seen in the cylindrical boiler room C, as well as

Claims (1)

By walling the boiler B , the heat gases still present after the fire has gone out, which remain inside the boiler wall for a long time, are used to preheat the water. Patent claims: Boiler for hot water heating, characterized in that the two boilers not connected to one another - heating boiler B and circulation boiler A ■ - each for itself in the outward and return lines of the radiators - main pipes c respectively. d are switched on and the circulation boiler (A) arranged above the water level of the heating boiler (B) is directly above the combustion chamber. At the under ι. The boiler marked the arrangement of FieId tubes (a ) protruding into the cylindrical combustion chamber (C) , of which the inner (a ¹ ) into the boiler room (A), the outer (a), passing through the latter, directly into the one after the radiators leading main pipe (c) open.
