As a high performance gas turbine, GT28 combines with a two-spool gas generator and a free power turbine. Under the condition of ISO, its power and efficiency are 28MW and 37% for marine mechanical propulsion, respectively. Considering the design characteristics and operating performance of GT28 gas turbine can meet the requirements of many marine propulsion, mechanical driven and electrical power generation, and this paper introduces the potential application of GT28 gas turbine in different industrial and marine fields. On this basis, the related key technologies are discussed briefly. Finally, a derivative network is presented to describe the relationships of different application and development of GT28 gas turbine.
