Conventional bearing turbo generator |
|
|
This turbo generator is fitted with unique propriety thrust bearing design. The package is skid mounted in order to have optimum and stable alignment of the turbine, high speed reducer and synchronous/asynchronous generator. Impellers are designed according to the needs of the process, out of a family of impellers that have been designed with the most modern computing tools for best efficiency and mechanical behaviour. The oldest units in operation are still running perfectly with a minimum of maintenance. |
|
Turbo Generator benefits:
low capital cost versus power production;
high efficiency in medium to high flow application;
dual stage expansion turbine with a single generator available;
specific seal gas solution avoiding any costly inert gas generator.

Magnetic bearing turbo generator |
|
|
 |
The magnetic turbo generator is made of a turbine wheel driving a high speed generator mounted on two magnetic bearings. The bearings keep the rotor in levitation thanks to electromagnetics flux generated by stator windings. The resulting electricity at high frequency is then converted into regular grid voltage through an inverter. |
|
Magnetic Turbo Generator benefits:
small footprint;
non contacting bearing technology eliminating bearing wear;
low operating costs (oil free design);
low mechanical losses allowing higher efficiency.
