Abstract

Die Erfindung betrifft einen Kessel für flüssige Brennstoffe, mit einem Brenner, der aus einer Verdampfereinheit (2) und einem zylindrischen Flammenerzeuger (4) aufgebaut ist, mit Heizflächen (11, 13) und mit einem Rauchgasabzug (17). Ein besonders hoher Wirkungsgrad kann dadurch erreicht werden, daß der Brenner als Vormischbrenner ausgeführt ist, bei dem in der Verdampfereinheit (2) der Brennstoff verdampft und mit Luft zu einem zündfähigen Gemisch vermischt wird und das Gemisch in den Flammenerzeuger (4) eingeführt wird, und daß der Flammenerzeuger (4) im wesentlichen konzentrisch innerhalb einer zylindrischen ersten Heizfläche (11) angeordnet ist, wobei der Vormischbrenner vorzugsweise lösbar mit einem die Heizflächen (11, 13) enthaltenden Teil (5) des Kessels verbunden ist, wobei vorzugsweise oberhalb der ersten Heizfläche (11) ein Umlenkkörper (14) vorgesehen ist, und bevorzugt radial außerhalb der ersten Heizfläche (11) eine weitere Heizfläche (13) angeordnet ist.

Figure 00000001
The invention relates to a boiler for liquid fuels, with a burner which is constructed from an evaporator unit (2) and a cylindrical flame generator (4), with heating surfaces (11, 13) and with a flue gas outlet (17). A particularly high efficiency can be achieved in that the burner is designed as a premix burner, in which the fuel evaporates in the evaporator unit (2) and is mixed with air to form an ignitable mixture and the mixture is introduced into the flame generator (4), and that the flame generator (4) is arranged essentially concentrically within a cylindrical first heating surface (11), the premix burner preferably being detachably connected to a part (5) of the boiler containing the heating surfaces (11, 13), preferably above the first heating surface (11) a deflection body (14) is provided, and preferably a further heating surface (13) is arranged radially outside the first heating surface (11).
