Flue gas collector for a boiler

The invention relates to a flue gas collector for a boiler with at least two wipers Heating gas flue limiting, essentially ring-cylindrical and horizontal water-jackets, being the water-jackets are arranged eccentrically to each other and the hot gas flows through the hot gas in a circumferential line, which from the Heizgassug through a lying on the rear face of the boiler at its lower area Flue gas extraction opening with an approximately circular segment-like Exit cross-sectional shape and through the flue gas collector placed on the flue gas outlet opening to the Chimney connected breath pipe can be suggleitet.

Because of their special construction and flue gas routing such boilers operated with a burner for liquid or gaseous fuels generally work with a certain overpressure in the combustion chamber. Because of

The flue gas collector 1 (Fig. 1) has a circular ring segment-like inlet nozzle 2, which is connected to the corresponding circular ring segment-like, on the rear face of the boiler at its lower. Area lying exhaust gas outlet opening of the boiler can be connected, and a circular outlet port 3 _? can be connected to the vent pipe leading to the sram chimney.

As shown in FIGS. 1 and 2, the flap 4 has a hook-shaped curved part 6 _S mix at the top, which the flap is pivotably and easily mounted on a Soharnasrstange 7 arranged on the housing of the Sauc'hgassanmlers. On both sides of the hook-shaped part 6, on the hinge rod 7, the two Fedex-n 5 designed as spiral springs are arranged, whose end oioh against the housing of the Eauchgasye ^ mlars 1 s.rötütKt and their free spring, shaped as a handle, on the side edge the'

Press the flap in the closing direction. The free J'ederanae of the spiral springs 5 can before; The side edge of the flap 4 can be lifted off, swiveled to the side, outward and placed against the housing wall of the smoke gas outlet 1 so that the flap 4 can be folded up without stress and can then be unhooked by the hinge rod 7. In this way, cleaning the boiler is made even simpler and easier.
