Principle of operation<\/span><\/span><\/span><\/h2>\n

Although both engines and gas turbines are used to produce electrical and thermal energy, they differ fundamentally in the way they achieve this goal.<\/span><\/span> Both devices use the energy of gases to produce mechanical work and often electrical energy.<\/span><\/span> However, they differ fundamentally in design and operation.<\/span><\/span> These differences affect their use in various fields.<\/span><\/span><\/span><\/p>\n

Construction<\/span><\/span><\/span><\/h2>\n

A gas engine consists of cylinders, pistons, a crankshaft, a valve train, a cooling system, and a lubrication system.<\/span><\/span><\/span><\/p>\n

A gas turbine consists of a compressor, a combustion chamber, and a turbine.<\/span><\/span> It is often equipped with additional components, such as a heat regenerator.<\/span><\/span><\/span><\/p>\n

Principle of operation<\/span><\/span><\/span><\/h2>\n

A gas engine is basically a large internal combustion engine where the combustion process of fuel (e.g. natural gas) takes place in cylinders.<\/span><\/span> The energy created by combustion causes the pistons to move, which transmit power to a generator or other devices via a crankshaft.<\/span><\/span> <\/span><\/p>\n

A gas turbine works on the principle of a continuous flow of compressed air, which is burned when mixed with fuel.<\/span><\/span> Hot exhaust gases drive a turbine, which in turn rotates a shaft connected to the generator.<\/span><\/span><\/span><\/p>\n

Analogy to transport<\/span><\/span><\/span><\/h2>\n

To better illustrate the difference between these two solutions, we can use a simple transportation analogy:<\/span><\/span><\/span><\/p>\n

    \n
  • A gas turbine is like a sports racing car:<\/strong> light, fast and very efficient at high loads.<\/span><\/span> However, its design is more complicated and its maintenance costs are high.<\/span><\/span> <\/span><\/li>\n
  • A gas engine can be compared to a truck.<\/span><\/span><\/strong> It is solid, durable and can carry large loads.<\/span><\/span> Its design is simpler and its operating costs are lower.<\/span><\/span><\/span><\/li>\n<\/ul>\n\n\n\n\n\n\n\n\n\n
