摘要： A heat recovery steam generator that includes a first steam drum for receiving a flow of water and steam from an evaporator. The first steam drum is adapted to provide the flow of water and steam to a second steam drum. The second steam drum is in fluid communication with the first steam drum and receives the flow of water and steam from the first steam drum and separates steam from the flow of water and steam to form a separated steam. There is a steam flow outlet positioned in the second steam drum, the steam flow outlet adapted to release the separated steam from the second steam drum.

摘要： In a combined gas/steam power plant with a once-through forced-flow steam generator, a separation bottle (25) is connected between the evaporator (22) and the superheater (23). To clean the water/steam circuit, in the full-load or the part-load mode, a larger quantity of water than necessary is conveyed through the economizer (21) and the evaporator (22) via a feed pump (20). The quantity of water is selected such that wet steam passes into the separation bottle (25). This water fraction, together with all the impurities contained therein, is separated in the separation bottle and is drawn off via a clarifying line (29). Overfeeding can be regulated in such a way that the fresh steam temperature corresponds to the nominal value of the respective load point. When cleaning of the water/steam circuit is intended in the full-load mode, and without overfeeding the system, steam from a stage of incomplete evaporation can be extracted out of the evaporator and led into the separation bottle. During cold starting, the supercooled water passing via the evaporator (22) into the separation bottle (25) and, later, the water separated from the generated wet steam, are discarded via the clarifying line (29) until the desired purity in the water/steam circuit is reached.

摘要： In a method for feed water control in waste heat steam generators, in particular drum boilers with a circulating pump (9) and drum boilers with natural circulation employed in combination power plants, wherein, by a three-component control by means of a superordinated level regulator (13) and a flow-through regulator (14) subordinated to the level regulator (13), the set value (S.sub.in) of the flow-through regulator (14) is displaced by the level regulator (13) in such a way that the level in the drum (6) is always regulated to the set value (S), regardless of interfering effects, the flow-through regulator (14) for the feed water flow (m.sub.s) is guided by the heat amount (Q.sub.AG) in the exhaust gas flow. The output signal of the flow-through regulator (14) for the feed water flow (m.sub.s) is limited, wherein as the function of the heat amount (Q.sub.AG) in the exhaust gas flow a selection is made between a limit value (m.sub.1) for the start-up operation and a limit value (m.sub.2) for normal control operation and the switch from (m.sub.1) to (m.sub.2) takes place via a time function element (16) with an idle time (T).

摘要： A mixed-pressure waste-heat boiler (7) has a forced-flow steam generator, essentially composed of a low-pressure economizer (15), of a low-pressure drum (17) and of a low-pressure evaporator (16), and a once-through forced-flow steam generator, essentially composed of a high-pressure economizer (21), of a high-pressure evaporator (22) and of a high-pressure superheater (23). The high-pressure economizer (21) is fed from the steam drum (17) of the forced-circulation steam generator via a high-pressure feed pump (20). Arranged between the high-pressure evaporator (22) and high-pressure superheater (23) is a separation bottle (25) which is connected to the steam drum (17) via a recirculation line (26). During startup, until superheated conditions are reached at the outlet of the high-pressure evaporator (22), high-pressure saturated water is recirculated into the drum (17) of the forced-circulation steam generator via the separation bottle (25).

摘要： A method of controlling stress in a boiler pressure vessel comprises limiting the diameter of a drum (10) of the boiler pressure vessel and preheating at least a portion of the wall (12) of the drum (10). Limiting the diameter of the drum (10) allows pressure in the drum (10) to be increased for a given mechanical stress. Furthermore, preheating the wall (12) of the drum (10) reduces peak thermally induced stresses in a material from which the drum (10) is fabricated.
