摘要： A steam generator(1) comprising a combustion chamber having funnel-shaped side walls (6) in the bottom area thereof and an encircling wall (4) formed from a plurality of steam generator pipes (12) through which a flow medium can flow, wherein there area as little temperature differences as possible in the flow medium at the output of the steam generator pipes (12). The steam generator pipes (12) are, more particularly, arranged in the lower section forming the funnel-shaped side walls (6) such that they are exposed to heat in as homongenous a manner as possible. According to the invention, the diameter of a number of steam generator pipes (12) in the region of the funnel-shaped side walls (6) is different from that in the region of the encircling wall (6).

摘要： The invention relates to a continuous steam generator (1) provided, in a duct for hot gas (6) circulating in a substentially horizontal direction (x), with a continuous heating surface (8) of an evaporator comprising a plurality of a steam generator (12) tubes which are mounted in parallel for circulating a fluid flow. The inventive device requires exceptionally low construction expenditures and ensures a high safety degree and a high efficiency. For this purpose, the continuous heating surface (8) of the evaporator is characterised in that it comprises a segment of the heating surface (26) through which a moving fluid (W) flows in an opposite direction with respect to the hot gas direction (x) and whose outlet (16) on the side of the moving fluid with respect to the heated gas direction is positioned in such a way that a saturated steam temperature which is adjusted during operation at the exit from said continuous heating surface (8) deviates from the predetermined maximum value of the temperature of the hot gas prevailing during operation at the outlet (16) of the segment of the heating surface. In addition, one or several entry collectors (14) are disposed at a closed distance from the inlet of said heating surface on the gas side in such a way that the moving fluid has a flow speed in the a downpipe (22) which is higher than the minimum speed required for pulling nascent steam bubbles.

摘要： The aim of the invention is to provide a suitable method for producing a continuous steam generator (1) that can operate at high steam pressures, said method being cost-effective and involving simple technology. This is achieved by a number of pipe segments (18), which are produced from a material of a first material category, are designed to form the steam generator pipes (12) and are combined into a number of modules (17). Each module (17) is equipped with a respective adapter (19) at a number of connection points that are designed to connect an additional module (17), said adapter being produced from a material of a second category.

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.

摘要： The invention relates to a fossil fuel fired continuous-flow steam generator (2) with a gas turbine combustion chamber (4) for fossil combustibles (B). On the heating gas side a vertical gas extractor (8) is mounted downstream of the horizontal gas extractor (6). The walls (9) surrounding the combustion chamber (4) are composed of evaporator tubes (10) which are welded together and vertically arranged. The aim of the invention is to provide a continuous-flow steam generator (2) which is especially easy to produce and assemble. During operation of the continuous-flow steam generator the temperature differences between adjacent evaporator tubes (10) of the combustion chamber (4) shall be kept as low as possible. To this end, the continuous-flow steam generator (2) is provided with a number of burners (30) which are arranged in the combustion chamber (4) at the level of the horizontal gas extractor (6). Also, for a number of evaporator tubes (10) which can be simultaneously impinged by the flow medium (S) the quotient from the steam generating capacity M (indicated in kg/s) at full load and from the sum A (indicated in m2) of the inner cross-sectional surfaces of said evaporator tubes (10) impinged simultaneously by the flow medium (S) is less than 1350 (unit kg/sm2).

摘要： The object of the invention is to ensure a fast, economical and reliable power regulation of a steam generating power plant (1) having a turbo set that comprises a steam turbine (2) and a generator (6) and during the operation of which water (W) is injected into or upstream of an overheater heating surface. According to the disclosed fast power regulating process of the steam generating power plant (1), the injection rate of water (W) is increased to adjust an additional generator output. In a steam generating power plant (1) which is particularly suitable for carrying out the process, an overheater heating surface of a steam generator (28) is provided with a water injector (70, 71) connected to a regulating component (82) for regulating the injection rate of water (W) into the overheater heating surface. The regulating component (82) supplies a regulating signal to the water injector (70, 72) depending on the required additional generator output.

摘要： In a fossil-fuelled steam generator (1) with a flue, the containig wall (2) of which takes the form of gastightly interconnected pipes (4), which are substantially vertically arranged and through which the medium can flow from bottom to top, the invention proposes that the pipes (4) have a greater inside diameter (d1) in a first or lower part (5) of the flue than the pipes (4) in a superimposed second part (7) of the flue. This ensures that the pipes (4) are reliably cooled. In addition, a greater than average heating of individual pipes (4) does not lead to unacceptable temperature differences between the outlets of the pipes (4).
