no. 1 Embodiment approach

[0034] figure 1 It is a figure which shows the schematic structure of the ship provided with the gas turbine combined cycle facility (it abbreviates to GTCC facility hereafter) which concerns on this embodiment. figure 2 It is a perspective view showing the configuration of the GTCC facility according to this embodiment, image 3 for following with figure 2 A perspective view of the GTCC facility according to the present embodiment viewed from different angles. Figure 4 It is a perspective view showing the structure of a waste heat recovery boiler installed in a GTCC facility.

[0035] Such as figure 1 As shown, the above-water facility in this embodiment liquefies natural gas, for example. This water surface facility includes a ship (floating body) F and 10A of GTCC facilities. Vessel F is used on-site at sea for the extraction of liquefied natural gas. GTCC facility 10A is installed on this ship F.

[0036] Such as figure 2 , image 3 As shown, GTCC facility 10A...

no. 2 Embodiment approach

[0112] Next, a second embodiment of the gas turbine combined cycle facility and marine facility according to the present invention will be described. In the second embodiment described below, the reference figure 1 , and the same reference numerals are assigned to the same configurations as those in the above-mentioned first embodiment, and descriptions thereof will be omitted.

[0113] Figure 6 It is a perspective view showing the configuration of the GTCC facility according to the embodiment according to the second embodiment.

[0114] Such as Figure 6 As shown, the GTCC facility 10B of the present embodiment mainly includes a gas turbine unit 20 , a waste heat recovery boiler 30 , an exhaust connection duct 32 , a compressor 80 , and a support frame 70 . The gas turbine unit 20 is driven by, for example, natural gas as fuel. The waste heat recovery boiler 30 generates steam by recovering waste heat of exhaust gas from the gas turbine unit 20 . The compressor 80 is us...

Abstract

The invention provides a gas turbine combined cycle facility and a water-surface facility. The gas turbine combined cycle (GTCC) facility (10A) provided with gas turbine units (20), heat recovery steam generators (30) for recovering heat and producing steam from exhaust gas produced by the gas turbine units (20), and exhaust ducts (32) for guiding the exhaust gas of the gas turbine units (20) to the heat recovery steam generators (30). At least some of the heat recovery steam generators (30) are disposed in the same plane as the gas turbine units (20), and the heat recovery steam generators (30) are disposed side-by-side so that the direction in which exhaust gas flows in the heat recovery steam generators (30) is parallel to the axial direction of the turbines of the gas turbine units (20).

Description

technical field [0001] The present invention relates to a gas turbine combined cycle facility installed on a ship or a floating body structure used on water, and a marine facility equipped with the gas turbine combined cycle facility. [0002] This application claims priority based on Japanese Patent Application No. 2013-132680 for which it applied in Japan on June 25, 2013, and uses the content here. Background technique [0003] Equipment including a gas turbine may be mounted on marine equipment used in a state of floating on water, such as a ship or a floating structure including a float floating in water. [0004] Examples of equipment equipped with such a gas turbine include equipment that extracts natural gas from offshore gas fields, liquefies it, and mounts it on a gas tank mounted on a gas carrier, and power generation equipment that drives a generator with a gas turbine. [0005] In order to increase the efficiency of these plants, there are gas turbine combined ...
