Abstract: A steam generator has a steam boiler, a burner shaft for receiving hot exhaust gasses from a burner extending into the steam boiler, at least one heat exchanger section with one or more channels extending through the boiler for conducting exhaust gasses from the burner shaft through the heat exchanger to an exhaust system. The connection between the burner shaft and the channels of the heat exchanger is by an opening in the sidewall of the burner shaft, which is partially closed by a slidable insert that allows adjusting the size of the opening. The insert can be hollow and can have an opening spaced from the opening in the sidewall to allow bypassing some exhaust gasses to a point in the channels downstream from the opening in the sidewall.

Abstract: A gas burner has an air delivery channel connected to a combustion chamber by a deflection element for deflecting the gas stream from the air delivery channel into the combustion chamber. The gas burner has an arrangement that will reduce the gas stream on the outside of the combustion chamber that is at a greater distance from the air delivery channel with reference to the flow direction in the air delivery channel in a section along a plane of the angle between the direction of the gas stream in the combustion chamber and the direction of the gas stream in the air delivery channel in favor of the gas stream on the inside of the combustion chamber that lies closer to the air delivery channel along the plane so that the gas stream in the combustion chamber is made more uniform with reference to the cross-section extending perpendicular to the direction of the gas stream in the combustion chamber.
