| 摘要 |
The steam generator installation has, seen in the direction of the gas flow, a high-pressure superheater heating surface (16), a high-pressure evaporator heating surface (15), a second high-pressure economiser heating surface (14), a low-pressure superheater heating surface (13), a low-pressure evaporator heating surface (12) and a first high-pressure economiser heating surface (11). The two high-pressure economiser heating surfaces (11, 14) are connected in series on the side of the working medium. By means of this arrangement and connection of the high-pressure economiser heating surfaces (11, 14), the part-load action of the steam generator installation is improved since in this load state no evaporation takes place in the economiser heating surfaces (11, 14). <IMAGE>
