Design Features of Steam Turbines for Use in the Sugar Industry
Steam turbines employed in the sugar industry require high thermodynamic efficiency and absolute reliability. The AEG-KANIS Steam Turbine Company, situated in Nuremberg, West Germany, and for many years a supplier to the South African industry, developed such turbines based on 30 years of experience with turbines for all industrial purposes. A special feature of these typical turbines used for ...
متن کاملNumerical Modeling of Wet Steam Flow in Steam Turbine Channel
In power station practice, work is extracted from expanding steam in three stages namely High Pressure(HP), Intermediate Pressure(IP) and Low Pressure(LP) turbines. During the expansion process in the LP turbine, the steam cools down and at some stages, it nucleates to become a two-phase mixture. It is well-acknowledged in the literature that the nucleating and wet stages in steam turbines are ...
متن کاملIntegration of Advanced Gas Turbine and Combined Cycle Technologies for High Efficiency with Operational Flexibility
While efficiency is still the major driver in combined cycle power plant design, there is an increasing need for operational flexibility along with additional operating cost reduction. nightly and weekend shutdowns and subsequent start-up capabilities should be considered during the overall evaluation of a power plant. Technological advancements in power plant design involving gas and steam tur...
متن کاملSilicone-polyether Copolymers as New Steam Turbine Oil Demulsifiers
Turbine oil plays an important role in supporting optimal steam turbine performance. Some additives in turbine oil can cause emulsification when the oil is contaminated by water, so demulsibility is a very important property of the steam turbine oil. In order to improve the demulsibility of steam turbine oil, two kinds of polyether-silicone comb copolymers are synthesized and used as steam turb...
متن کاملTests on High-Reaction Compressor Blading
Two sets of blading, designed for 120 per cent reaction, and for flow coefficients of 0" 667 and 1.0 respectively, have been tested in the N.G.T.E. low-speed compressor No. 106. The performances were compared with those of corresponding sets of 50-percent reaction blading and with predictions based on simple theoretical methods. The high-reaction bladings both gave efficiencies which were lower...
