METHOD FOR MANUFACTURING A MICRO GAS TURBINE

摘要

The invention relates to a method for manufacturing an inexpensive micro gas turbine 1. According to this method, an existing compressor-turbine unit is divided into two separate parts being a compressor 3 and a turbine 5. The compressor and turbine shafts are joined. Two existing bearing units (11 and 17) are taken, wherein one of them may belong to the existing compressor-turbine unit. The rotor 25 of an existing generator 7 is mounted on the joined shaft. A generator housing 21 is manufactured and connected to the bearing units. The stator 23 of an existing generator 7 is mounted into the generator housing. Energy input into the working cycle of the gas turbine can be implemented by adding either an internal burner or external burner with a heat exchanger. By using inexpensive and often mass produced off-the-shelf components, a cost effective micro gas turbine can be derived.
