What is Steam Turbine - Description and Characteristics.
The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected.
Fluid Catalytic Cracking Process Engineering Essay INTRODUCTION. Fluid catalytic cracking process, which is now more than 60 years old, is the cornerstone of most of the petroleum refineries. It has proven to be the most-efficient process available for the conversion of gas oils and residue into more valuable lighter hydrocarbons.
The combustion of fuel, a chemical energy conversion process, generates heat to convert water into steam at a very high temperature and pressure. The heat energy contained in the steam drives the huge turbine, converting heat energy into rotating mechanical energy. Coupled to the turbine.
Solar Turbine. Solar Turbine Generator is a device that uses steam from a Solar Power system to convert the sun’s heat into usable electric energy. A solar turbine generator can absorb the sun’s heat using a concentrated solar panel system or a thermal solar panel.
The steam turbine is one kind of heat engine machine in which steam's heat energy is converted to mechanical work.The construction of steam turbine is very simple.There is no piston rod,flywheel or slide valves attached to the turbine.So maintenance is quite easy.It consists of a rotor and a set of rotating blades which are attached to a shaft and the shaft is placed in the middle of the rotor.
The process of condensing the steam usually creates a vacuum, which then brings in more steam from the steam turbine. The water is returned to the steam generation system, reheated and reused. The governor is a device that controls the turbine’s speed.
The steam turbine system is used to create over 80 percent of the world's electricity supply. In order for the turbines to work, steam must first be created from an energy source. These include fossil fuels, solar energy, geothermal energy and nuclear energy.
