摘要： A coal-fired steam generator that has a water-steam circulation and a low pressure-heat carrier-circulation which, via a heater that is disposed in the flue gas flow of the steam generator and that has at least one heat transfer surface, absorbs heat from the flue gas flow and conveys this heat to a process that utilizes heat, especially a gas turbine process in conjunction with a coal-combination unit having a steam turbine connected in the water-steam circulation. To optimize the position of the heater for the low pressure-heat carrier-circulation, especially a sodium circulation, there are provided at least two flue gas passes that are connected in parallel with a combustion chamber of the steam generator, whereby the flue gas flow coming from the combustion chamber is distributed to these flue gas passes, at least one of which is associated with a water-steam circulation, while the other is associated with the low pressure-heat carrier-circulation.
