Title:
The turning gear for gas turbine composition
Document Type and Number:
Japanese Patent JP6239821
Kind Code:
B2
Abstract:
An apparatus for driving a load is disclosed. The apparatus includes a multiple-shaft gas turbine (103) comprising: a high pressure compressor (107) and a high pressure turbine (109) drivingly connected to one another by a first gas turbine shaft (113); a low pressure compressor (105) and a power turbine (111) drivingly connected to one another by a second gas turbine shaft (115), extending coaxial with the first gas turbine shaft, the high pressure compressor and the high pressure turbine. The apparatus further includes a load coupling (121) drivingly connecting the power turbine to the load. A dual-speed turning gear (141) has an output shaft drivingly engageable to and disengageable from said load, for slow-rolling the load or for turning the low pressure compressor, along with the turbomachinery drivingly connected thereto, during offline washing.
