Abstract
Gas turbine unit comprising a high pressure turbine (10) driving a high pressure compressor (11), and a low pressure turbine (13) driving a low pressure compressor (14) and a generator (12), a combustion chamber supplying gas to the compressors, and a recuperator (18) for heat exchange between exhaust gas and compressor air, the low pressure turbine having an adjustable geometry and an adjustable connection (20) being provided bypassing the recuperator, and a method in operating the gas turbine unit wherein the electrical power is adjusted to a desired value by changing the geometry of the low pressure turbine and the heat power is adjusted by adjusting the bypass flow to a desired value.
