QDRA70 gas turbine generating set which adopts Siemens’ SGT200 gas turbine possesses the characteristics of simple design, reliable operation, less emission, and excellent performs. It is able to burn liquid fuel and gas fuel of different kinds. The modular integrated design concept is adopted in the generating set. The modules are assembled as an integrated unit and installed on a standard base after the pre-assembly and the factory testing, which is very convenient for transportation, installation and field maintenance. During industrial power generating, the heat in the high temperature exhaust from the gas turbine can be reused by the heat recovery boiler, which makes the whole comprehensive heat efficiency up to 85%.
