Title:
SYSTEM FOR INCREASING POWER GENERATION EFFICIENCY BY CONTROLLING INLET AIR TEMPERATURE OF TURBINE
Document Type and Number:
WIPO Patent Application WO/2021/162390
Kind Code:
A1
Abstract:
The present invention provides a system for increasing power generation efficiency by controlling inlet air temperature in a power generator rotating a turbine by means of a fuel such as LNG or oil, the system unaffected by external temperature by adjusting the temperature of air flowing into a gas turbine. The present invention comprises: a brine circulation unit (10) for heat-exchanging inlet air flowing into a compressor of a gas turbine (2); a first gas heat exchange unit (20) which extends and connects to a circulation line (14) and cools a brine by means of heat exchange with a liquefied gas supplied from a fuel tank (1); a hot heat exchange unit (30) which is connected to the circulation line (14) and heats the brine by using the exhaust heat of the gas turbine (2) as a heat source; a second gas heat exchange unit (40) which heat-exchanges a liquefied gas supplied from a fuel tank (2) into a vaporized gas by using the exhaust heat of the gas turbine (2) as a heat source; and a control unit (50) for controlling the operation of the first and second gas heat exchange units (20) (40) and the hot heat exchange unit (30).
