Articulated boiler

The invention relates to a sectional boiler with boiler = members that share a common, preferably tubular Form burners on both sides assigned heat exchange surfaces.

According to an older proposal, it has already been provided in order to enlarge these heat exchange surfaces Area above the burner's ribs of the kettle glisder protrude with heat exchange surfaces running transversely to the burner axis. These ribs should preferably be formed by half members, which are arranged with these ribs facing each other on both sides of the burner are; they should be located between the groups running across the axis of the burner at a distance from each other arranged burner openings extend.

The present invention is based on the knowledge that, especially with atmospheric steel _{burners, a considerable reduction in the NO y} content of the exhaust gases can be achieved, in particular by cooling the flame feet of the burner can flow in unhindered below and this Flammön

\ Above the burner openings a sufficiently large

dimensioned combustion zone remains in which it is of Cooling fins or the like. Internals remain undisturbed.

According to the invention, the boiler sections are located directly above the burner openings Area of protruding ribs that serve to cool the feet of the burner flames.

According to a preferred embodiment of the invention = subject matter are ribs formed by the boiler sections above the burner flames and those in the area the ribs protruding into the base of the flame in the area of these burner flames through a rib-free combustion zone separated from each other, in which an undisturbed combustion can take place.

Further features of the invention are the better Ver = clarity because of the following with reference to the drawings, an embodiment of the articulated boiler illustrate.

Fig. 2 a section according to II-II of Fig.l.

The boiler half-members 1 each enclose a cavity 2 to be filled with water and point to the tubular Burner 3 facing heat exchange surfaces 4 each have one or more vertically extending ribs 5, which their = on the other hand, the additional, transverse to the burner axis 6 Form heat exchange surfaces 7 which are located between the burner flames 8 lined up in transverse arrays

The burner openings 10 are parallel to one another and extend transversely to the longitudinal axis 6 of the burner 3 Arranged flocks and the dump trucks used to cool the flame feet. 11 he ^^ tx-ikon is immediately above of these burner openings 10 between these flocks arranged at a distance from one another.

The one from the boiler half-links 1 above the burner =

flames 8 formed ribs 5 and those in the area of the

I ribs 11 protruding from the base of the flame are in the height range i

of the burner flames 8 by a rib-free combustion = |

I zone 12 separated from each other so as not to have these flames 8 |

to be disturbed by built-in components and not to impair the access of the secondary air.

The ribs 5 and 11 of the boiler half-links 1 can be designed to be full or hollow within the scope of the invention, in order to allow the heating medium to also circulate in these cavities in the latter case.

Of course, within the scope of the invention, various =
