Definitions

  • the invention relates to a low-temperature boiler with a combustion chamber receiving the burner, a downstream heating gas train ending in the exhaust pipe and a surrounding boiler water jacket.
  • 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.
  • 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.
  • the boiler temperature is controlled so that it comes to lie above the dew point of the heating gases.
  • correspondingly complex measures have to be taken.
  • 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 boiler water jacket is divided into two layers into a primary (inner) and secondary (outer) circuit, that two openings make two connections between the primary and secondary circuit, at least one of the connections having a temperature-controlled valve, which sets the primary circuit at a high temperature and the secondary circuit at a low temperature and that both the primary and secondary circuit are provided with supply and return connections.
  • the boiler water jacket surrounding the combustion chamber and partially the heating gas flue is double-shelled and divided into a primary (inner) and a secondary (outer) area, which are connected to one another via (at least) two openings.
  • at least one of the connections is provided with a temperature-controlled valve which is set such that the balance between the primary and secondary circuits can only be incomplete, so that the primary circuit is set and maintained at a much higher level than the secondary.
  • Such a double-shell boiler water jacket construction has the advantage that condensation is avoided, optimal energy utilization takes place, and both high-temperature water can be provided from the primary circuit and low-temperature water from the secondary circuit.
  • the highly heated water is connected, for example, to high-temperature devices such as process water and boilers, and the low-temperature water to the radiators. From an energetic point of view, it is an advantage that only a small part of the water is kept at a comparatively high temperature and, at the same time, the energy losses can be minimized by the surrounding second shell of the boiler water jacket of low temperature. There is only immediate heating of the primary circuit, which releases part of its medium to the secondary circuit via the temperature-controlled valve.
  • At least one connection is required through which the medium passes from the primary into the secondary circuit in a controlled manner and, in addition, a second connection through the compensation flow back into the primary circuit, i.e. the supply of cooler heating medium from the secondary to the primary circuit.
  • the flow that takes place via one connection is temperature-controlled via a valve, whereby only a single connection is to be controlled in this way, since a corresponding compensation flow takes place through the second.
  • the jacket arranged between them is either insulated and / or has a double-shell construction.
  • the dew point of the heating gases must not be fallen below at any point in the inner boiler water jacket. Comparatively cool heating medium flows in, especially at the inlet of the primary circuit, which could result in a local temperature drop below the dew point. For this reason, it is suggested that the inflowing water, both from the return of the external high-temperature, be expedient raturilless or represent the equalizing flow from the secondary circuit to distribute or adjust in terms of area, so that you get a kind of mixing chamber principles and not only a certain point is flowed to.
  • the opening serving as the inlet or outlet of the primary circuit in the secondary circuit is design as a connection which points upwards and in a second it ends essentially coaxially surrounding nozzle.
  • This arrangement has the effect that the hot heating circuit medium emerging from the primary circuit by thermal convection becomes in the second connecting piece surrounding it and, due to the temperature gradient, cannot flow appreciably into the secondary circuit. Then the heat applied is primarily used only to heat the primary circuit from which the process water is taken, and the secondary circuit receives heating medium at a higher temperature only to a minor extent.
