Application of nano materials to enhance creep strength of platen super heater tubes and to minimize boiler outage in ultra super critical power plants.

Abstract :

Power generation through fossil fuel power plants is one of the basic needs to rescue the gap between power supply and demand. It is a continuous process to minimize the gap between supply and demand. Clean and efficient power generation needs incorporation of advance technologies in traditional system of power generation. Power production in fossil fuel power plants is totally based on optimum utilization of available heat energy to produce high quality steam and to achieve this goal availability of the steam is to be optimized. Latest modifications in rankine cycle are not sufficient to justify optimum utilization of heat available. Nano–structured materials posse’s special properties in comparison with the material with identical composition with normal grain size. This paper will report my work on the nano–structured alloy and composites to improve creep strength in super heater tubes in boiler. Composites and micro structures are two important variables can be used as characteristic variables to improve high temperature strength of super heater tubes. Nano materials can be used to improve thermodynamic properties of tube material such as high temperature creep strength and micro structural degradation at high temperature can be minimized to optimize boiler outage during power generation.
