Investigation on Last Stage High Pressure Steam Turbine Blade for Producing Electricity

摘要

The investigation on design of high pressure steam turbine blade addresses the problems of steam turbine efficiency. A precise focus on aerofoil profile for high pressure turbine blade and it gages the effectiveness of certain like Chromium and Nickel in resisting creep and fracture in the turbine blades. The thermal and chemical conditions in blades are, substrate from to prevent the corrosion when exposed to wet steam. The efficiency of the steam turbine is a key factor in both the environmental and economical collisions of any coal-fired in power stations. The increasing efficiency of a typical 500 MW turbine by 1% reduces emissions of CO2 from the turbine location, with corresponding reductions in NOx and SOx. In this connection an attempt is made on steam turbine blade performance is important criterion for retrofit coal fired in power plant. Based on the research presented modifications to high pressure steam turbine blades can be made to increase turbine efficiency a turbine. The results and conclusions are presented for a study concerning the durability problems experienced with steam turbine blades.
