Title:
COGENERATION SYSTEM AND ITS OPERATING METHOD
Document Type and Number:
Japanese Patent JP3924489
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To increase the output of a gas turbine while securing a reliability at a low cost by collecting valuable processed water contained in the exhaust of the gas turbine in a cogeneration system.
SOLUTION: This cogeneration system comprises a turbine side regenerator 4 for preheating air flowing in the combustor 2 of the gas turbine 2 by collecting heat from the exhaust of the turbine 2 driving a generator 6. A thermally driven refrigerator 12 is driven by collecting the heat from the exhaust passed through the turbine side regenerator 4 by a refrigerator side regenerator 13. The system also comprises a moisture collecting and feeding device collecting the moisture by utilizing cold generated from the exhaust discharged to the atmosphere after passing through the refrigerator side regenerator 13 by the thermally driven refrigerator 12 and feeding the collected water to the air on the suction side of the turbine 2.
