2. Outline Machine Specification 2.1 General Requirements A specification for the prototype machines was developed by the partner companies: The use of a microturbine should provide low cost electricity generation from low steam flows. To make an attractive investment, it must have low life cycle costs. For the widest application, there should be no possibility of steam contamination. To embrace the widest range of applications the microturbine was specified so as to have an electrical output power from the package of 50kW. By using two microturbines in one package a 100 kW unit was specified.
