Title:
GAS TURBINE SYSTEM UTILIZING AIR OF HIGH MOISTURE CONTENT
Document Type and Number:
Japanese Patent JP2015025415
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gas turbine system utilizing air of high moisture content capable of improving water recovering efficiency and power generation efficiency.SOLUTION: A gas turbine system utilizing air of high moisture content comprising: a gas turbine system composed of an air compressor, a combustor performing combustion with compressed air and a fuel, and a gas turbine driven by a combustion gas; a humidification regenerative cycle composed of a humidification tower for adding moisture content to the compressed air, and a regenerator allowing the humidified air to exchange heat with a gas turbine exhaust gas; and a water recovery device to which the exhaust gas is introduced from the regenerator to recover the moisture content included in the exhaust gas. A cooling system for cooling the inside of the water recovery device to recover the moisture content, is a closed cycle composed of: a low boiling point medium-evaporator using a medium of a low boiling point as a cooling material, exchanging heat between the exhaust gas and the medium of low boiling point, and condensing the moisture content of the gas turbine exhaust gas; and a low boiling point medium-condenser disposed outside the water recovery device to exchange heat between the medium of low boiling point and cooling water to condense the medium of low boiling point.
