Combined cycle power plant - Wikipedia

In electric power generation a combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy to drive electrical generators.The principle is that after completing its cycle (in the first engine), the temperature of the working fluid in the system is still high enough that a second subsequent heat engine extracts ...

FUNDAMENTALS OF GAS TURBINE ENGINES

The type of operation for which the engine is designed dictates the performance requirement of a gas turbine engine. The performance requirement is mainly determined by the amount of shaft horsepower (s.h.p.) the engine develops for a given set of conditions. The majority of aircraft gas turbine engines are rated at standard

Extruder Principles and Operation - Google Books

This book is intended to fill a gap between the theoretical studies and the practical experience of the processor in the extrusion of thermoplastic polymers. The former have provided a basis for numerical design of extruders and their components, but generally give scant attention to the practical performance, especially to the conflict between production rate and product quality.

Overview of Proximity Sensors | OMRON Industrial Automation

Detection Principle of Inductive Proximity Sensors. Inductive Proximity Sensors detect magnetic loss due to eddy currents that are generated on a conductive surface by an external magnetic field. An AC magnetic field is generated on the detection coil, and changes in the impedance due to eddy currents generated on a metallic object are detected.
