VTA MicroTurbine

The generator operates at the same speed as the turbine (up to 96,000 rpm) because the permanent magnet is located directly on its drive shaft. The high-frequency alternating current (1,600 Hz) generated in this way is rectified in the turbine''s power electronics and subsequently reversed to alternating current again (50 Hz / 400 V).

6 FAQs about [Romania ultra micro turbine]

What is an ultra-micro scale gas turbine (umgt)?

1. Introduction An ultra-micro scale gas turbine (UMGT) is a miniaturised microscale gas turbine that generates electricity, and it is comprised of 5 main components: a radial turbine, a radial compressor, bearings, a combustor, and an electrical generator .

What is a microturbine (Mt)?

A microturbine (MT) is a small gas turbine with similar cycles and components to a heavy gas turbine. The MT power-to-weight ratio is better than a heavy gas turbine because the reduction of turbine diameters causes an increase in shaft rotational speed.

How much power does a microturbine produce?

MIT's millimeter size turbine will deliver 500–700 Wh/kg (820–1,140 kJ/lb) in the near term, rising to 1,200–1,500 Wh/kg (2,000–2,400 kJ/lb) in the longer term. A similar microturbine built by the Belgian Katholieke Universiteit Leuven has a rotor diameter of 20 mm and is expected to produce about 1,000 W (1.3 hp).

What is a microturbine used for?

Microturbines can be used for cogeneration and distributed generation as turbo alternators or turbogenerators, or to power hybrid electric vehicles.

How many RPM does a microturbine rotate?

They comprise a compressor, combustor, impeller / turbine and electric generator on a single shaft or two. They can have a recuperator capturing waste heat to improve the compressor efficiency, an intercooler and reheat. They rotate at over 40,000 RPM and a common single shaft microturbine rotate usually at 90,000 to 120,000 RPM.

How much power does a turbine have?

Early turbines of 30–70 kW (40–94 hp) grew to 200–250 kW (270–340 hp). They comprise a compressor, combustor, impeller / turbine and electric generator on a single shaft or two. They can have a recuperator capturing waste heat to improve the compressor efficiency, an intercooler and reheat.
