    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.

    摘要： The invention relates to a steam generator (1) comprising a combustion chamber having a peripheral wall (2) formed at least partially from gas-proof, welded steam generator pipes, at least two additional inner walls (4, 8) formed at least partially from additional steam generator pipes which are arranged inside the combustion chamber, and said inner walls are connected one behind the other on the flow medium side by an intermediate collector (6). The aim of the invention is to provide a steam generator which has a particularly high service life and is particularly reliable. Said flow medium on the inlet (12) of the inner wall (4) upstream of the intermediate collector (6) has a lower temperature than that of the flow medium on an inlet (10) of the peripheral wall (2).

    摘要： Evaporator surface structure of a circulating fluidized bed boiler (10), comprising at least one separate vertical evaporator surface unit (26) arranged within a distance from the furnace walls (22 ), formed of water tube panels (28, 30, 54, 56, 52, 64 ) extending from the bottom (18) of the furnace of the circulating fluidized bed boiler (10) to the ceiling (20) thereof, the evaporator surface unit (26) consisting of two cross-wise joined vertical water tube panels (28, 30, 54, 56, 62, 64 ). Preferably, a first water tube panel (64) of each evaporator surface unit is parallel to the water tubes (84) of the furnace ceiling (20) and a second water tube panel (62 ) is perpendicular to that. The upper ends of the water tubes of each water tube panel are preferably connected to separate headers (36, 38) parallel with the water tube panels (62, 64), and the water tube panels (62, 64) are advantageously suspended to hang of the headers (36, 38) in such a way that each evaporator surface unit is connected to the ceiling (20) of the furnace (12) by a structure enabling vertical movement between the evaporator surface unit and the ceiling.

    摘要： The invention relates to a steam generator (1, 1', 1'), in which a continuous heating surface (8, 10, 12) is located in a fuel gas channel (6) that can be traversed in an approximately horizontal fuel gas direction (x). Said continuous heating surface comprises a number of steam generator pipes (22, 50, 60) that are connected in parallel (W) for the passage of a flow medium and is designed in such a way that a steam generator pipe (22, 50, 60), which is heated to a greater extent than another steam generator pipe (22, 50, 60) of the same continuous heating surface (8, 10, 12), has a higher throughput of the flow medium (W) than the other steam generator pipe (22, 50, 60). The aim of the invention is to produce a low-cost steam generator with a particularly high level of mechanical stability, even when subjected to different thermal stresses. To achieve this, the or each steam generator pipe (22, 50, 60) has a respective downpipe section (34, 52, 62, 64), which is approximately vertical and through which the flow medium (W) can flow downwards and a respective riser pipe section (36, 54, 66, 68) connected downstream of the downpipe on the flow medium side, which is approximately vertical and through which the flow medium (W) can flow upwards.
