MICRO-GAS TURBINE PLANT AND METHOD FOR OPERATING A MICRO-GAS TURBINE PLANT

摘要

The invention relates to a micro-gas turbine plant (1) comprising a combustion chamber (30) for generating exhaust gas by combustion of fuel supplied to the combustion chamber (30), a turbine (40) arranged in an exhaust gas line (50) downstream of the combustion chamber (30) for expanding the exhaust gas to a pressure below atmospheric pressure, a compressor (42) arranged downstream of the turbine (40), and a device assigned to the turbine (40) for extracting energy, wherein the combustion chamber (30) has a primary gas supply for the addition of primary gas, in particular primary air, which participates in the combustion in a primary combustion zone (33). A particularly flexible and low-emission micro-gas turbine plant (1) is obtained by supplying secondary gas, in particular secondary air, to the combustion chamber (30) downstream of the primary combustion zone (33), and by arranging upstream of the combustion chamber (30) at least one adjustment device (12) for adjusting the ratio between primary and secondary gas during operation of the micro-gas turbine arrangement (1).
