Summary:
Through the design experience developed for steam turbines and available to gas turbines, it is not surprising that gas generator compressors, turbines, and power-extraction turbines bear a striking resemblance to each other and to the steam turbine. Nor should it be surprising that the axial flow compressors of today’s gas turbines resemble the reaction steam turbine with the flow direction reversed. While many people today recognize the similarities between steam and gas turbine components, most do not fully appreciate the common history these two products share. History tells us that the idea for the gas turbine and the steam turbine were conceived simultaneously. As early as 1791, John Barber’s patent for the steam turbine described other fluids or gases as potential energy sources. “John Barber invented what may be considered a gas turbine in which gas was produced from heated coal, mixed with air, compressed and then burnt. This produced a high speed jet that impinged on radial blades on a turbine wheel rim.”1 John Barber’s ideas, as well as those before him (Giovanni Branca’s impulse steam turbine—1629, Leonardo da Vinci’s “smoke mill”—1550, and Hero of Alexandria’s reaction steam turbine—130 BC)2 were just ideas. Even though the gas turbines described by these early visionaries would today be more accurately termed ‘turboexpanders’ (the source of compressed air or gas being a by-product of a separate process), there is no evidence that any of these ideas were ever turned into working hardware until the late 19th Century.

    Actually during my previous working experience in the oil operating facilities I would like to get more knowledge in the types of gas turbines
