Abstract:
A steam generator comprising:a steam boiler,a burner shaft extending into the boiler for receiving hot exhaust gasses from a burner, andat least one heat exchanger section with at least one channel extending through the boiler for conducting exhaust gasses of the burner through the steam boiler so that heat in the exhaust gasses is transferred through walls of each channel to the liquid in the boiler, each channel at one end being connected to an exhaust and at the other end being connected to the burner shaft by a connecting section, each channel being arranged so that a flow direction of the gasses flowing in the channel is different from a flow direction in the burner shaft, the connecting section comprising a passage that is formed by an opening in a wall of the burner shaft and an insert, whereby the opening connects the burner shaft to each channel of the heat exchanger section and is partly closed by the insert.
