Abstract

A steam generator in which a main boiler is provided and at least one fluidized bed furnace is connected with the main boiler and is operated independently of the furnace of the main boiler. The fluidized bed furnace is connected with the main boiler underneath the boiler funnel. The tubes of the boiler funnel are partially fanned out and form flue gas passages, through which the flue gas of the fluidized bed furnace flows into the combustion chamber of the main boiler.
