Gas turbine


Gas turbine 
Enerzia Power Solutions a pioneer in design and manufacturing renewable energy sources entered the area of Gas Turbine manufacturers . A gas turbine, also called a combustion turbine, is a type of internal combustion engine. It has an upstream rotating compressor coupled to a downstream turbine, and a combustion chamber in-between. Energy is added to the gas stream in the combustor, where fuel is mixed with air and ignited. In the high pressure environment of the combustor, combustion of the fuel increases the temperature. The products of the combustion are forced into the turbine section. The Gas Turbine Award is given in recognition of an outstanding individual--or multiple--author contribution to the literature of combustion gas turbines or gas turbines thermally combined with nuclear or steam power plants. The paper may be devoted to design aspects or overall gas turbines or individual components and/or systems such as compressors, combustion systems, turbines, controls and accessories, bearings, regenerators, inlet air filters, silencers, etc.

The advantage of Gas Turbines in generating electricity is the environmental friendly nature as there is no major combustion gases and accumulation of coal ash as in the thermal power systems. Gas Turbine Manufacturers designs the turbines with lot of fuel flexibility.  There, the high velocity and volume of the gas flow is directed through a nozzle over the turbine's blades, spinning the turbine which powers the compressor and, for some turbines, drives their mechanical output. The energy given up to the turbine comes from the reduction in the temperature and pressure of the exhaust gas. It may cover topics specifically related to gas turbines such as high temperature materials or fuel considerations, including erosion and corrosion complications. A gas turbine train is a passenger train that uses one or more gas turbines as its main source of power. Few passenger trains use this system today, although there has been one recent prototype built by Bombardier Transportation.


They can be adapted to use almost any flammable gas or light distillate petroleum products such as gasoline, diesel and kerosene which happened to be available locally. Whe­n you go to an airport and see the commercial jets there, you can't help but notice the huge ­engines that power them. Most commercial jets are powered by turbofan engines, and turbofans are one example of a general class of engines called Gas turbine power engines. It can also be devoted to application or operational aspects of gas turbines for aircraft propulsion and ground power units, or automotive, electric utility, gas pipeline pumping, locomotive, marine, oil field pumping, petrochemical, space power, steel, and similar uses. Papers published anywhere in the world are eligible. Sequential combustion can be visualised as a gas turbine comprising two combustor-turbines in series, where the exhaust gases from the first turbine feed the combustor of the second.
