effect of Steam Inlet Temperature on performance of partial admission Steam turbine
2014Co-Authors: Rahul Singh, Abhishek Arya, Vikas Gupta, Sphurti Sweta PandeyAbstract:4Energy analysis helps designers to find ways to improve the performance of a system in a many way. Most of the conventional energy losses optimization method are iterative in nature and require the interpretation of the designer at each iteration. Typical steady state plant operation conditions were determined based on available trending data and the resulting condition of the operation hours. The energy losses from individual components in the plant is calculated based on these operating conditions to determine the true system losses. In this, first law of thermodynamics analysis was performed to evaluate efficiencies and various energy losses. In addition, variation in the percentage of carbon in coal content increases the overall efficiency of plant that shows the economic optimization of plant.

Cast Alloys for Advanced Ultra Supercritical Steam Turbines
National Energy Technology Laboratory (U.S.), 2010Co-Authors: Holcomb G. R., Wang P., Jablonski P. D., Hawk J. A.Abstract:The proposed Steam Inlet Temperature in the Advanced Ultra Supercritical (A-USC) Steam turbine is high enough (760 °C) that traditional turbine casing and valve body materials such as ferritic/martensitic steels will not suffice due to Temperature limitations of this class of materials. Cast versions of several traditionally wrought Ni-based superalloys were evaluated for use as casing or valve components for the next generation of industrial Steam turbines. The full size castings are substantial: 2-5,000 kg each half and on the order of 100 cm thick. Experimental castings were quite a bit smaller, but section size was retained and cooling rate controlled to produce equivalent microstructures. A multi-step homogenization heat treatment was developed to better deploy the alloy constituents. The most successful of these cast alloys in terms of creep strength (Haynes 263, Haynes 282, and Nimonic 105) were subsequently evaluated by characterizing their microstructure as well as their Steam oxidation resistance (at 760 and 800 °C)
