Definitions
- the invention relates to a heating device with afterburner according to the preamble of claim 1.
- Such a device is known from DE-OS 2820297, where it is proposed to arrange a so-called additional burner tube on the burner tube, which has nozzle-like passages distributed over the circumference and leading to the burner tube mouth, the task of which is to convey air to the mouth of the burner tube to improve combustion.
- the additional burner tube is attached to the burner tube in its mouth area.
- DE-OS 2442170 provides for the attachment of a hollow cylinder which coaxially surrounds the burner at a distance and which is adjusted so that it glows at its outlet end. This measure serves to evaporate fuel.
- the hollow cylinder is dimensioned and the burner is set such that the hollow cylinder glows from the outlet end to the openings and that a lamella fastened to the inside of the hollow cylinder is arranged between two openings.
- the flames and exhaust gases emanating from the burner are forced to pass through the hollow cylinder and are kept within the volume of the hollow cylinder and cannot, as in the prior art, spread throughout the burner chamber .
- the gas flowing through has a higher speed in the area of the cross-sectional constriction and consequently forms a lower static pressure, which causes air to be sucked in from outside through the openings in the hollow cylinder, which is swirled as it passes, which is better Mixing of the gas inside the cylinder results.
- the cylinder glows at least on the outlet-side edge, as a result of which the fuel-air mixture which has not yet burned is ignited and consequently used.
- boilers according to the invention which have just been described are suitable for both gaseous and liquid, in particular oily, fuels.
- the result of the lamellae facing inwards on the openings and attached to the cylinder is that the effectively available flow cross section is reduced in the regions defined thereby, the velocity of the gas located there is consequently increased and the negative pressure is thereby increased.
- the result is an increased intake of air and in addition the generation of turbulence.
- the lamella can be assigned to a larger number of openings as a one-piece element or as a single part to a single opening.
- the openings are in a circle along the jacket of the cylinder.
- the burner is set so that the hollow cylinder glows up to the openings on the circle. This requirement is easy to meet, since comparatively cool air is sucked in from the outside through the openings and heat is therefore constantly removed from these areas of the hollow cylinder, so that spreading of the annealing process beyond the circle can be easily avoided and prevented by appropriate setting.
- the embodiment according to claim 2 causes a longer residence time of the outflowing flue gases in the burner chamber and thus an improved heat emission.
- it is fundamentally free whether the closed end of the respective cylinder is located on the inlet-side or on the outlet-side end of the hollow cylinder.
- a cylinder with its closed end face adjoins and surrounds the burner tube outside and coaxially with the hollow cylinder and in this way facilitates the return of air from the heated area on the outlet side back to the inlet between the burner tube and the hollow cylinder.
