摘要： 1,130,767. Steam turbine power plant. L. & C. STEINMULLER G.m.b.H. Dec.9, 1966, No.55284/66. Headings F1Q and F1T. A method of controlling the temperatures of reheat steam in a steam turbine power plant comprises producing secondary steam in a secondary steam generator by abstracting superheat from bled steam and controllably introducing the secondary steam into the interstage reheaters to increase the volumetric steam flow therethrough. The plant includes Fig. 1, a main steam generator 1, high (H.P.) and low (L.P.) pressure main turbines 2, 21, secondary turbine 17, reheater 11, and secondary steam generators 4, 13. Super-heated steam tapped at 3 from the H.P. turbine 2 flows through the steam generator 4 and in giving up its super-heat, before being condensed in a feedwater heater 5, generates secondary steam from feedwater flowing through line 66 and taken from the feedwater pump 15. Secondary steam is also generated by steam tapped at 12 from the L.P. turbine 21 giving up heat to feedwater flowing through the generator 13. Both streams of secondary steam combine in line 61 to flow to the secondary turbine 17. Some secondary steam is tapped off from turbine 17 through line 19, under the control of valve 20, to mix in line 8 with the main steam flow from H.P. turbine 2 to the reheater 11, thus reducing the temperature of the mainsteam upstream of the reheater, increasing the volumetric flow therethrough and thereby reducing the temperature of the reheated steam entering the L.P. turbine 21. A small quantity of main steam flowing from H.P. turbine 2 towards L.P. turbine 21 is tapped adjacent a check valve 7 to flow to a feedwater heater 10. If the degree of reheat in the reheater 11 is too low, then the steam flow through the reheater can be reduced by tapping steam from the reheater inlet line 8 through a line 58 and a valve 59 to a low pressure stage of secondary turbine 17. The temperature of the reheated steam thus rises since the flow is reduced with an unchanged heat supply. The exhaust steam from turbine 17 flows through line 18 to the feedwater reservoir 14. In a modified plant, Fig.3, two reheaters 11, 35 and two secondary turbines 17, 45 are provided. In this case the secondary steam raised in secondary generators 13, 37 can be optionally introduced into the main steam generator 1 through a valve 38, or fed through a valve 39 to the first secondary turbine 17. In the latter case, the expanded steam from turbine 17 flows through check and control valves 41, 42 to mix at 43 in the first reheater 11 with the main steam flow to thus cool the reheated steam flowing to turbine 21. The steam from turbine 17 may alternatively flow through a valve 44 to join the secondary steam from secondary generators 4, 36 flowing to the additional secondary turbine 45. Steam can be tapped through valve 46 from turbine 45 to control the reheat in second reheater 35. In a further modification Fig. 2 (not shown), the plant has a single secondary turbine (23) supplied with secondary steam at different pressures from secondary generators (4, 24, 29), higher and lower pressure tappings (31, 33) from the turbine controlling the flow in higher and lower pressure reheaters (11,35), respectively.

摘要： 998,831. Regulating steam temperature In boilers. COMBUSTION ENGINEERING Inc. Dec. 13, 1963 [Dec. 28, 1962 (3)], No. 49274/63. Heading F4A. The reheat vapour temperatures in a supercritical forced flow once through vapour generator supplying a 3-stage turbine, operating on a double reheat cycle, are maintained constant throughout a substantial load range by regulating the flow of recirculation gases and by varying the furnace gases outlet temperature. The generator comprises a furnace 10 tangentially fired by an assembly of burners having nozzles 24 vertically adjustable to move the combustion zone from A to B and horizontal and vertical gas passes 14, 16. A fan 82 passes exhaust gases through duct 88 containing damper 94 into the bottom of the furnace for recirculation and through duct 86 containing damper 92 into the top of the combustion zone for temperating the furnace gases. The working fluid is circulated by a pump 40 in series flow through an economizer 32, a mixing vessel 44, furnace-cooling tubes 34, tubes lining gas pass 16 and superheater sections 36, 38 containing bundles of sinuously or otherwise bent tubes connected in parallel, before passing through the high, intermediate and low pressure stages 64, 70, 80 of a turbine 64 and through high and low pressure convection heated reheaters 66, 70 immediately upstream of the intermediate and low-pressure turbine stages respectively. With respect to the flow of combustion gases the low-pressure reheater is downstream of the high pressure reheater and separated from it by superheater section 36. A recirculation circuit for providing adequate flow through the furnace cooling tubes at low loads and during start-up connectsthe upper header 48 of the tubes through pump 119 and valve 120 to the mixing vessel 44. The pressure and temperature of the primary vapour entering the first turbine stage are maintained constant by temperature and pressure responsive means 108, 109 controlling, via actuators 114, the air and fuel flow control valves 28, 31 of the burners and, via actuator 116, the feed water control valve 81. The outlet temperature of the high-pressure reheater 66 is maintained constant by temperature sensing means 96 which varies the furnace gases outlet temperature by first controlling via actuator 100 and damper 92 the flow of the tempering gases and when this flow is completely stopped, tilting the burner nozzles upwards by operating actuators 122. The output temperature of the low-pressure reheater is -maintained constant by the temperature-sensing means 102 controlling the flow of recirculation gases via actuator 106 and damper 94. In a second embodiment the positions and methods of temperature control of the reheaters are interchanged, in this case the nozzles are tilted downwards. In another embodiment with the reheaters positioned as in Fig. 1, the highpressure reheater is heated mainly by radiation. As this has different heat exchange characteristics, regulation of the low-pressure reheat temperature by control of the recirculation flow results in a high pressure reheat temperature close to the desired value and it can be maintained constant by tilting up or down the burner nozzles, no tempering gases being required. Alternatively, control of tempering gases can be used in lieu of burner tilt control.

Motor power plant.-In a high pressure steam power plant, the auxiliary engines are driven by steam generated in a boiler heated by waste gases from the main boiler. A low pressure water-tube boiler g is arranged in the path of the gases from a high pressure water-tube boiler e. In a high pressure return-tube boiler, a low pressure water-tube boiler is fitted in the uptake. The heating of the low pressure boiler may be controlled by dampers and the boiler may in addition be separately heated.

摘要： Die Erfindung betrifft eine Verbrennungskraftwerksanlage mit einer Verbrennungsanlage, in der ein Brennstoff unter Entwicklung hochkorrosiver Rauchgase verbrannt wird, einer Heißluftturbineneinheit, die mit einem gasförmigen Arbeitsfluid arbeitet, und einem oder mehreren Wärmeübertragern, der oder die zur Übertragung von thermischer Energie aus der Verbrennungsanlage auf das Arbeitsfluid geeignet sind. Mindestens einer der Wärmeübertrager enthält mindestens ein keramisches Hochtemperatur-Wärmerohr, dessen erstes Ende in der Verbrennungsanlage und dessen zweites Ende außerhalb der Verbrennungsanlage und innerhalb des Strömungsweges des Arbeitsfluids der Heißluftturbineneinheit angeordnet sind. Die Verbrennungskraftwerksanlage weist darüber hinaus eine Leitung auf, die geeignet ist, die Abluft der Heißluftturbineneinheit direkt der Verbrennungsanlage als Verbrennungsluft zuzuführen. Damit wird die Effizienz der Gesamtanlage aus Verbrennungsanlage und Turbine und die Standzeit des oder der Wärmeübertrager durch einen besseren Schutz vor Korrosion, Oxidation/Reduktion bzw. Abrasion erhöht.
