THM1304 Generatorantrieb
Typical applications
Gas turbine generator units are operated for e.g. emergency and black start applications, on off-shore platforms (with adapted package design) mainly in simple cycle mode
For CHP1) applications (most common) gas turbine generator units are operated in combination with a heat recovery unit for different heat processes, resulting in e.g. – Power, Steam Generation – Power, Hot Water Generation – Power, Steam & Chilled Water – Power, Steam & Hot Water
CHP applications are benefi cial for various industries such as food processing, pulp & paper, breweries, automotive, etc. having demand for heat and power. CHP processes provide increased effi ciencies and reduced CO2 emissions compared to conventional power & heat generation. Overall CHP effi ciencies reach 90% and higher depending on the heat process.
