The power shaft, which is driven
by the main shaft via a gearbox, is connected to a generator
to produce electricity. The electrical power is supplied to three
15 kW fan heaters that can be switched on individually to vary
the load condition. The fuel is burnt in a single silo, reverse-flow
combustion chamber equipped with a pressure-swirl atomizer.
This atomizer produces a hollow cone spray with an angle of 90–
100. The specifications of the gas turbine are listed in Table 1
