(1.)
The compressor draws in the combustion air via the generator into the turbine. In order to drive the microturbine, the air is first preheated with the waste heat of the generator..
At the same time, the generator is cooled with the intake air.
(2.)
The air in the compressor is then compressed to 3.8 bar above atmospheric pressure. It heats up to around 200°C.
(3.)
The air, which is heated to 500°C in the recuperator, flows into the combustion chamber..
(4.)
In the combustion chamber, the air is mixed with the fuel and ignited.
|
(5.)
The combustion gas is directed into the combustion chamber.
(6.)
The hot combustion gases expand in the turbine and thus drive the compressor and the generator. The generated mechanical work is converted in the generator to electrical power.
(7.)
After the exhaust gases have transferred some of their thermal energy to the combustion air in the recuperator, they exit the microturbine at an exhaust temperature of 280°C.
(8.)
The thermal energy of this exhaust air can pass through a downstream heat exchanger to supply process heat or thermal energy for heating.
