LAYOUT STRUCTURE OF FLOATING STORAGE GAS POWER PLANT

摘要

The present invention relates to a layout structure of a floating storage gas power plant and, more specifically, to a layout structure of a floating storage gas power plant, comprising: a cargo system for storing liquefied natural gas in a floating structure and loading and unloading the liquefied natural gas; a fuel gas supply system provided in the floating structure in order to vaporize the liquefied natural gas of the cargo system into fuel gas and supply the fuel gas; a gas turbine power generation system including a gas power generation unit operated by the fuel gas supplied from the fuel gas supply system, and a first power generator for producing electric power by means of the gas power generation unit; a heat recovery steam generator (HRSG) for generating steam by using waste heat of exhaust gas generated from the gas power generation unit; and a steam turbine power generation system including a steam turbine operated by the steam supplied from the HRSG, and a second power generator for producing the electric power by means of the steam turbine, wherein the fuel gas supply system is disposed at the stern. According to the present invention, the floating storage gas power plant is divided into a safety zone in which a residential section is placed, and a danger zone in which the fuel gas supply system, the gas turbine power generation system, the HRSG and the steam turbine power generation system are arranged, thereby minimizing the risk of a fire or explosion.
