PURPOSE:To make it possible to easily carry out maintenance and management of a generator by disposing rotary bodies of the main engine of the titled plant into an arrangement in which a gas and steam turbines are provided on one side of the generator and rigid couplings are used in coupling rotary bodies respectively. CONSTITUTION:In the titled palnt, a generator E1, a gas turbine GT and a steam turbine ST3 which are rotary bodies of the main engine in the order of GT2-ST3-E1 or ST3-ST2-E1. Further, the generator E1 is coupled to a starting device 8 through a slip ring 10. A thrust bearing 4 is installed in the shaft system between the turbines GT2 and ST3, while the respective rotary systems 1-3 are coupled by rigid couplings 9. By this arrangement, at the time of maintenance and inspection of the generator E1, particularly at the time of drawing out the rotor, the operation is carried out without dismantling the turbines GT2 and ST3. |
