Title:
PARTIAL ADMISSION OPERATION TURBINE APPARATUS FOR IMPROVING EFFICIENCY OF CONTINUOUS PARTIAL ADMISSION OPERATION AND METHOD FOR OPERATING TURBINE APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/110827
Kind Code:
A1
Abstract:
The present invention provides a partial admission operation turbine apparatus comprising: a rotor portion rotatably coupled to a rotary shaft of a turbine and including a plurality of rotor blades; a nozzle portion fixedly coupled to the rotary shaft in front of the rotor portion and guiding and supplying a working fluid to the rotor blades through a plurality of nozzle blades; and an inlet disk coupled to the rotary shaft in front of the nozzle portion in a plate shape and having a plurality of admission holes formed therein so as to supply the working fluid to the nozzle portion to partially admit the working fluid into the nozzle portion, wherein each of the admission holes is formed to have a different cross-sectional passage area, so that the opening and closing of the admission holes are controlled according to operating flow rate conditions to control a partial admission ratio of the working fluid supplied to the nozzle portion. Due to the aforementioned feature, since continuous partial admission can be operated for a supercritical power generation system, it is possible to resolve the difficulties in designing and manufacturing turbines. Also, since the partial admission ratio can be adjusted according to operating conditions, it is possible to improve the performance of a turbine that is operated by continuous partial admission. Furthermore, even if the operating flow rate conditions change in the same cycle, it is possible to operate the same turbine with high efficiency.
