A fuel-powered turbine is a turbine that is powered by a fuel (ie a liquid or a gas). Unlike ie steam turbines, the fuel burned is immediatelly used to turn the turbine blades. As such, the step of converting fuel to steam is skipped and fuel-powered turbines are hence more efficient then steam turbines. This article specifically focuses on turbines of a small size intented for the purpose of local electricity supply.
Both gas and liquid-fueled microturbines should be distinguished, as they vary slightly in regards to the design.
DIY gas and liquid-fueled microturbines
The simplest form of self-constructed gas turbine employs an automotive turbocharger as the core component. A combustion chamber is fabricated and plumbed between the compressor and turbine sections. The Schreckling design constructs the entire engine from raw materials, including the fabrication of a centrifugal compressor wheel from plywood, epoxy and wrapped carbon fibre strands.
Several companies have started to produce microturbines, mostly for the purpose of energy production, as well as for use as a "range extender" in electric vehicles.
Notable companies are:
- Bowman Power produces the TurbogenTM microturbines
- Elliot Energy Systems
- Ingersoll-Rand (IR)
- Turbec AB
- Micro Turbine Technology BV
- Biofuel turbine engine term
- Homemade turbine projects
