extraction steam
3.Unit no. 1 in Huaneng Beijing Thermal Power Plant is a 145 MW extraction steam turbine manufactured by Ural Steam Turbine Factory in Russia, and has adopted a governing system with co-existence of electric and hydraulic modes.
4.The paper presents introduction to how Shanghai Steam Turbine Co. Ltd(STC), after having become a joint venture with Westinghouse Co, has successively employed the licenced technical achievements to the development of cogeneratioin extraction steam turbines of the 100MW～300MW class and to raise its product development potency and increase its market shove.
6.WEISS KESSEL ANLAGEN MASCHINENBAU GMBH is well-known not only in Dillenburg with Silos of steel, Vertical-tube radiant boilers and Boiler plants as well as with Long-distance heating plants, Dust extracting installations and Combustion chamber boiler, but also with further offers, like Thermal oil, Heat plants and/or Mechanical boiler furnaces, Air and dust extraction technology and Steam boilers and steam generators.
7.Before steam admission, valve on vacuum hogging extraction line（the valve is befor hogging pipe of the Two Stage Steam Jet Ejector） should be closed (see also Two Stages Steam Jet Ejector Installation and Operation Instruction).
8.The essential oil and extractum are extracted from its stem, leaf and flower by steam distillation and solvent extraction. According to the analysis, it contains 0.1003% essential oil and 0.74% extraction in average.
9.The 20 constituents in essential oil of the branches and leaves of the Sabina Vulgaris antoine were extracted by steam distillation-extraction, and identified by capillary gas chromatography and gas chromatography-mass spectrometry.
10.The #9 and #10 142MW heat supply units in GanSu XiGu power plant, the steam extraction main pipe system adopt WESTATION control system of Westing House Company and DEB coordination control policy in design.
