Definitions

  • the invention relates to a low-temperature boiler with a burner-receiving combustion chamber, a downstream heating gas train ending in the exhaust pipe and a surrounding boiler water jacket, whereby in addition to the heating gas train located above and / or below the combustion chamber, additional heating gas trains are also connected upstream, as seen in the flow direction.
  • low-temperature boilers of the generic type are used. Their basic task is to transfer the gas or oil introduced and ignited via the burner as heat to the surrounding boiler water and to feed it into the heating system. For reasons of improving energy use, more and more low-temperature boilers have been used recently, in which the boiler water is kept at a comparatively low temperature in order to reduce heat losses.
  • Such a low-temperature heating boiler is known from DE-A-36 04 842, in which, in addition to the heating gas train ending in the exhaust gas pipe, additional auxiliary heating gas trains are connected upstream in the flow direction for better energy utilization.
  • the invention has set itself the task of further developing low-temperature heating boilers in which condensation is avoided and at the same time an optimal use of energy is possible.
  • the entrances to the heating gas flue and the auxiliary heating gas flues are closed by flaps and have a positive control by means of which one flap is opened and the other flap is closed.
  • a certain part of the heating gas leaving the combustion chamber then flows through the auxiliary heating gas trains before reaching the (main) heating gas train and can give off additional energy there.
  • the result is better energy utilization and less heat loss through the fireplace.
  • the heating gas draft is to be understood as the duct that is connected directly upstream of the flue pipe leading to the chimney and through which the heating gases flow. It is therefore the last part of the boiler through which flow is seen in the direction of flow. Both the secondary and main throttle cable are surrounded by the primary circuit of the boiler jacket.
  • the entrances to the auxiliary heating gas flues and to the heating gas flue are closed by flaps close.
  • the user has the appropriate control whether the heating gases coming from the combustion chamber initially flow through the auxiliary heating gas flues or immediately through the (main) heating gas flue to the outside. Due to the forced control, the flap to the auxiliary heating gas flues can be closed and the other opened when starting. The result of this is that, when the main flue gas flap is fully open, rapid heating occurs in these areas, the dew point in the flue pipe and / or in the boiler water passes through and the optimum heating circuit temperature for the chimney can be reached quickly. No condensation can occur in the auxiliary heating gas flues that are cold during this period due to the lack of heating gases.
  • the flaps to the auxiliary heating gas flues open and the flaps to the main heating gas flue close, so that all heating gases are forced through the auxiliary heating gas flues and the heat absorption of the boiler water and consequently also the energy utilization is improved.
  • the flaps can be controlled, for example, using a thermostat.
  • a particularly preferred realization of the idea according to the invention consists in the use of two or more concentric tubes which are inserted from one end.
  • the inner serves as a heating gas pipe and the one or the outer, which represent cylindrical annular spaces, as auxiliary heating gas flues.
  • the auxiliary heating gas flues stand one below the other or with the heating gas flue on the front in connection with each other in such a way that when the inlet flap is opened, the auxiliary heating gas flue (s) first flows through and then the exhaust gases enter the (main) heating gas flue. A direct flow through the exhaust gases is then not possible.
  • the exhaust gases are immediately released to the outside via the (main) heating gas flue without the auxiliary heating gas flues being acted on.
  • the advantages of the proposed construction can be seen in the ease of cleaning, in which the tubes are pulled out and the chambers are accessible for cleaning.
  • the low-temperature heating boiler shown consists of a combustion chamber (1) in which the burner (2) is located and in which the heating gases flowing out according to the arrows are formed by combustion.
  • An inner tube (5) and an outer tube (6) are arranged coaxially in both the annular space (4) and the main heating gas train (3) to form the auxiliary heating gas trains (5), the inside in the main heating gas train (3) and the outside (6) engages in the annular space (4) at a distance from the outer walls.
  • the boiler water jacket is divided into a primary circuit (10) and a secondary circuit (11).
  • the primary circuit (10) operating at a higher temperature surrounds the combustion chamber (1), the (main) heating gas flue (3) and the auxiliary heating gas flues formed by the annular space (4). Only the primary circuit (10) is then immediately heated.
  • For heating the secondary circuit (11) there are two openings (12), one of which is in the form of a nozzle (13) which in turn engages in a nozzle (14) acted upon by the medium of the secondary circuit. This construction counteracts the tendency of the medium of the primary circuit (10) to escape from the opening (12) caused by thermal convection.
  • the other, here left opening (12) is the starting point of a connection having a controlled valve and a pump and opening into the secondary circuit (above and / or below). As a result, the amount of water flowing from the primary to the secondary circuit is adjusted; the other, right opening here only provides a compensation option.
