Definitions
- Such a boiler is from EP 0 191 147 B1 known. It is equally suitable for oil and gas firing. Different performance levels are possible the number of heating pipes being adjusted accordingly.
- the flue gas guide inserts leave the boiler as a condensing boiler work. However, an operation is also without Recovery of latent heat of condensation possible, if the chimney system requires higher flue gas temperatures. In in this case, the flue gas guide inserts at least partially removed.
- the combustion chamber dips into the water jacket from above and has a side, heat-insulating lining.
- the Burner is located on the side of the boiler and penetrates with its burner tube the water jacket and the Sidewall of the combustion chamber.
- the burner therefore blows the flue gas directly into the heating pipe into it, so that an energetically unfavorable deflection of the flue gas is eliminated.
- the entire heat input also takes place into the water jacket over the heating pipe. So it takes not the heating of a thermal surrounding the combustion chamber Insulation.
- the water jacket becomes unique penetrated by the heating tube. So there is no side Breakthrough of the well-known boiler, which served the Connect the burner to the combustion chamber. A considerable one constructive simplification is the result.
- the flue gas guide inserts can, as in the known Construction, pot-shaped and with its upper, radially outwardly projecting edge to the Adjacent the heating tube, being nozzle-like in its side wall Have passage openings. It is special advantageous that the top, the combustion chamber delimiting Leadership deeper than the following lead missions is trained. Accordingly, it also shows a higher one Number of nozzle openings. This takes into account the fact that the flue gases reach their maximum when they exit the flame Own volume.
- the heating tube is preferably made as a one-piece jacket Stainless steel trained.
- the Boiler a condensate collecting tray inclined to the horizontal on, which forms an intermediate floor of the heating tube and passes into a lateral condensate drain pipe. The condensate is thus from the heating pipe directly into the drain pipe initiated.
- the flue gas guide inserts can, as in the known Construction supported by a central pole be, it being particularly advantageous that the Support the rod on the condensate collecting tray. It deals a structurally particularly favorable construction.
- the Flue gas pipe above the condensate collecting tray on the side from the heating pipe All pollutants are therefore from Heating pipe led directly out of the boiler without to charge further interior spaces of the boiler. This represents an extremely inexpensive for environmental reasons and thereby extremely simple construction.
- Fig. 1 shows a schematic representation of an axial vertical section by a boiler according to the invention.
- the boiler has a housing 1, which one Contains water jacket 2.
- the water jacket 2 is on a flow line 3 and connected to a return line 4.
- the water jacket 2 is heated by a heating pipe 5 enforced.
- the heating tube 5 is up over the water jacket 2 led out and forms with its upper section a combustion chamber for a fall burner 6. This is on the upper end of the heating tube 5 is arranged. The fall burner 6 thus blows the hot flue gases directly into the heating pipe 5 in.
- the heating tube 5 contains a plurality of flue gas guide inserts 7, which are cup-shaped and with their Adjacent the upper, radially protruding edge to the heating pipe. They have nozzle-shaped openings in their side wall 8 on.
- the flue gas is progressively going from top to bottom Guided inside the guide inserts 7 and leaves them through the nozzle-like passage openings 8, with smoke gas jets form that on the inner surface of the water-cooled Hit the heating tube 5.
- the flue gas cools down progressively so strong that the condensable ones Components of the flue gas with appropriate heat emission liquefy.
- the uppermost flue gas guide insert 7 is higher than the following leading missions and points accordingly also a larger number of nozzle-like openings 8 on. This takes into account the fact that the flue gas at the outlet of the fall burner 6 has its maximum volume.
- the condensate runs on the inside wall of the stainless steel manufactured, one-piece heating tube 5 down and meets an inclined condensate collecting tray 9 there passes into a condensate drain connector 10. Above the Condensate collecting base 9 branches a side flue gas line 11 from the heating tube 5. So all pollutants are from the heating pipe directly from the housing 1 of the boiler led out without further interior spaces of the boiler act upon.
- the heating tube 5 is supported on a bottom sheet 12 of the Boiler. It also guides the weight of the flue gas guide inserts 7 in the base plate 12.
- the flue gas guide inserts 7 are namely attached to a central rod 13, which is supported on the condensate collecting base 9.
- the boiler can with a plurality of heating pipes, each of which a condensate drain pipe and a flue gas pipe exhibit.
- the Flue gas guide inserts can be designed so that the condensate partly flows into the pilot operations and there again evaporates. The pollutants then form a crust the pot bottoms, which are easily removed during the course of maintenance can be.
