ARRANGEMENT STRUCTURE OF FLOATING AND STORAGE GAS POWER PLANT

摘要

The present invention relates to an arrangement structure of a floating storage gas power plant. The arrangement structure of a floating storage gas power plant is provided to store liquefied gas (LNG) in cargos of the floating storage gas power plant and produce electricity using the LNG, minimize the length of a hull by arranging a steam turbine power generation system on the optimal position of the upper part of a hull deck, and improve the structural stability of the hull by lowering the center of gravity of the hull. The structure comprises: a cargo system (1000) storing liquefied natural gas in a floating structure (10), and loading and unloading the liquefied gas; a fuel gas supply system (2000) installed on the floating structure (10) to evaporate the liquefied gas of the cargo system (1000) into fuel gas; a gas turbine/engine power generation system (3000) which includes a gas power generation unit (3100) operated by fuel gas supplied from the fuel gas supply system (2000), and a first generator (3200) producing electricity by the gas power generation unit (3100); a waste heat recovery steam generator (HRSG) (4000) generating steam by the waste heat of exhaust gas generated from the gas power generation unit (3100); a steam turbine power generation system (5000) including a steam turbine (5100) operated by steam supplied from the waste heat recovery steam generator (4000), and a second generator (5200) producing electricity by the steam turbine (5100). The steam turbine power generation system (5000) is arranged on the upper part of a deck.
