Steam Turbines for Biomass Plants

Turbine Steam Chest Life Assessment

The optimal approach to condition assessment, regardless of the component involved, is to use a programmatic approach, and steam chest condition assessment is no exception. Steam chests typically vary significantly from one to the next in shape and complexity; consequently, stress distributions vary and damage occurs first and is most advanced at the high stress regions, accordingly. One of the...

Avoiding Stressed-Out Steam Turbines

assembly, Pro/ENGINEER CAD geometry was imported into ANSYS Mechanical software and meshed using SOLID185 elements. Frictionless surface-tosurface contact pairs with augmented Lagrangian algorithms were created between mating surfaces. A matching node pattern was maintained at the root and slot pressure faces, where load transfers take place between the two components. As an in-house design pra...

Power Plants, Steam and Gas Turbines WebQuest

A WebQuest is an Internet-based and inquiry-oriented learning activity. The aim of this work is to outline the creation of a WebQuest entitled “Power Generation Plants: Steam and Gas Turbines.” This is one of the topics covered in the course “Thermodynamics and Heat Transfer,” which is offered in the second year of Mechanical Engineering at the Defense University Center at the Naval Academy in ...

Developments in Steam Turbines for the Sugar Industry

Demands for higher outputs have been met by careful tailoring of steam turbines for both mechanical and electrical power generation to meet the needs of thermal efficiency and reliability at an econoinic cost. Major system components and the methods chosen for speed control are described. Important operational requirements are featured.
