Due to industrialization and huge household usage of electricity there is energy crises world wide. There is reduction of natural sources oil, water reservoirs, to make cheaper energy aerodynamic based Gas Turbines in combine & open cycle power plant are commonly used for electricity. Hydro power generation is also very cheep and dual benefit source of power generation. The aim of this forum is to share experience and awareness about modern techniques and up coming events in energy sector.

GAS TURBINE
A gas turbine, also called a combustion turbine, is a rotary engine that extracts energy from a flow of combustion gas. It has an upstream compressor coupled to a downstream turbine, and a combustion chamber in-between. (Gas turbine may also refer to just the turbine element.)
Energy is added to the gas stream in the combustor, where air is mixed with fuel and ignited. Combustion increases the temperature, velocity and volume of the gas flow. This is directed through a (nozzle) over the turbine's blades, spinning the turbine and powering the compressor.
Energy is extracted in the form of shaft power, compressed air and thrust, in any combination, and used to power aircraft, trains, ships, generators, and even tanks.
