Knowledge about small turbomachines

It shows the natural frequencies of a rotor plotted against speed. From it, you can see at which speeds resonances may occur and whether the operating range is clear of them.

A heat exchanger that uses the hot exhaust gas from the turbine to preheat the compressed air before it enters the combustor. This saves fuel and significantly increases the electrical efficiency of small gas turbines.

Fuel gases with a low calorific value, for example from landfills, sewage treatment plants or wood gasification. They ignite less readily and burn more slowly than natural gas and need combustors designed for them.

A plant generates electricity and usable heat at the same time. In a micro gas turbine, the heat from the exhaust gas is used, for example for space heating or process heat.

An approach to product development. Requirements are broken down step by step to the individual component and then verified in reverse order, from component testing to the acceptance run of the complete machine.

The testing of every single machine at the end of series production. At a test station, the most important functions and measured values are checked before the machine is delivered.
