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.
