  • GB-A-792 747 discloses a boiler with one Boiler room, which is made up of a heat exchanger special coiled pipe into a pipe wrapped by the heat exchanger Fire chamber and an exhaust gas chamber surrounding the heat exchanger divides. Opposite an arranged on the front, Fireclay flame pot, in which for the commissioning of the Arrange a boiler head, not shown, in the boiler is a head assembly is formed on which the hot gases are redirected and swirled. Through the Turbulence gets unburned gases from the periphery back to the central flame.
  • the influx of fresh ignited air / fuel mixture into the combustion chamber creates an overpressure with which the exhaust gases openings between the windings of the heat exchanger tube in a ring channel outside the heat exchanger become.
  • the exhaust gases can be close to the head arrangement get into a first ring channel, in this to Flow on the burner side and in a second outer ring channel back again. In a simpler embodiment they reach the burner side within the combustion chamber, and step through the openings into the ring channel. In this The flue gas flows in the other direction again to a fireplace.
  • a burner head is inside the flame pot to arrange which is the heat exchanger before the radiant heat protects the flame and the burner head.

  • Another advantage is that by turning the flame Furnace is better used and more compact than with a long, thin flame shape. In particular the entire length of the firebox is practically uniform suitable for heat transfer to a heat exchange medium, because the burning head is covered by the flame.
  • the heat exchanger advantageously has at or near at least one end of a final organ, which the Combustion chamber limited in the longitudinal direction. This is in addition to the exhaust gas chamber around the heat exchanger formed yet another chamber in which exhaust gas from the Exhaust chamber flows.

Even if gas burners are used in the boiler according to the invention can find, so the burner is advantageous Oil burners because oil can be stored in simple tanks and these can easily be refilled. The dependence from a pipeline network can thus be avoided. The Handling oil is also much less dangerous than the handling of gas which, so it is not through a network is distributed under pressure in appropriate pressure tanks must be filled.
  • the burner is advantageously switchable or switchable on gas operation.
