Design and Analysis of a High Pressure Steam Turbine

Abstract

Pressure contact and do as it has done in the analysis of the easiest bolts in recent years due to the availability of high computing capacity and flexibility in the methods of calculation using finite element analysis. In this paper, is one such analysis of the mixture of manual calculations and finite element analysis to evaluate steady contact pressure in the casing of the steam turbine high pressure state. The work involves design considerations and controls design, validation and sensitivity analysis to achieve a design to meet the structural requirements for mechanical safety standards. In recent years fundamental changes focused on the design of the steam turbine to improve efficiency, reliability and reduced operating costs. Siemens power generation, for example, the efficiency and availability of steam turbines by reducing energy losses have improved vapor flow in each of the components of steam turbines. The steam turbine unit greatly affects the efficiency and reliability of the power plants. Any improvement in the design of steam turbine may be a more efficient use of fuel and results in cost reduction. The high pressure steam at 565 ° C and 156 bar pressure passes through the high pressure turbine. The exhaust steam of this section is returned to the boiler to heat before use. To exit heating boilers and redo, and enters turbines medium pressure steam at 565 ° C and 40.2 bar pressure. Turbine medium pressure steam expansion still in three low-pressure turbines. The steam entering the turbine is 306 ° C and 6,32 bar. For the most jobs steam remains in the exhaust pressure is too low. Thus, witnesses, and turned the envelope of steam power at work in stages HP and IP. Therefore, the cover design is a very important aspect.
