摘要： The invention relates to a method for operating a forced-flow steam generator operating at variable pressure and at a steam temperature above 650° C. and reducing the minimum forced-flow load of the forced-flow steam generator, wherein the forced-flow steam generator is incorporated in the water-/steam-conducting working medium circuit of a power plant and the economizer of the forced-flow steam generator comprises at least one high-pressure pre-heater and/or a heat transfer system for pre-heating the working medium, the at least one high-pressure pre-heater and/or the heat transfer system being arranged upstream as viewed in the working medium circuit direction, wherein if a predetermined partial load point (LT) is exceeded, the heat absorption of the working medium within at least one high-pressure pre-heater and/or the heat transfer system is reduced in such a way that the temperature of the water/steam working medium at the outlet of the economizer is below the boiling point relative to the corresponding economizer outlet by a predetermined temperature difference (TD), and a forced-flow steam generator for performing the method.

摘要： The invention relates to a forced-flow steam generator for burning dry brown coal without assistance from recirculated waste gas in the combustion chamber thereof. Said forced-flow steam generator (1) comprises a combustion chamber (2) and a waste gas flue (3) connected to the upper end thereof, and peripheral walls (4) surrounding said flue. Said walls (4) are formed from tubular walls (5), the tubes thereof guiding the water/steam working medium. The combustion chamber (2) comprises at least one burner (6), and downstream heating surfaces (7) are arranged in the waste gas flue (3). Part of the peripheral walls (4) is covered in the region of the combustion chamber (2) by at least one bulkhead heating surface (8), the size of which on the surface side being determined such that the heat absorption of the peripheral walls (4) and therefore the temperature thereof are reduced to a value enabling the formation of the peripheral walls (4) from modified, heat-resistant 2.25-2.5% chrome steel that does not require any heat aftertreatment following the welding treatment thereof.
