Description

Container ship {Container ship}

The present invention relates to a container line.

Liquefied natural gas (Liquefied natural gas), Liquefied petroleum gas (Liquefied petroleum gas) and other liquefied gas are widely used in place of gasoline or diesel in recent technology development.

Liquefied natural gas is a liquefied natural gas that is obtained by refining natural gas collected from a gas field. It is a colorless and transparent liquid with almost no pollutants and high calorific value. On the other hand, liquefied petroleum gas is a liquid fuel made by compressing gas containing propane (C3H8) and butane (C4H10), which come from oil in oil field, at room temperature. Liquefied petroleum gas, like liquefied natural gas, is colorless and odorless and is widely used as fuel for household, business, industrial, and automotive use.

Such liquefied gas is stored in a liquefied gas storage tank installed on the ground or stored in a liquefied gas storage tank provided in a ship which is a means of transporting the ocean. The liquefied natural gas is liquefied to a volume of 1/600 The liquefaction of liquefied petroleum gas has the advantage of reducing the volume of propane to 1/260 and the content of butane to 1/230, resulting in high storage efficiency.

These liquefied gases are supplied to various customers and used. Recently, LNG carrier that uses LNG as fuel for LNG carriers that transport liquefied natural gas has been developed. The method used is applied to ships other than LNG carriers.

Especially, in case of a container ship carrying cargo such as a container, it is necessary to increase the cargo load to increase the transportation efficiency. However, in the case of a propulsion vessel using liquefied gas, a two-stroke large-scale engine (ME-GI, XDF) must be applied as a propulsion engine. Therefore, when the propulsion engine for using liquefied gas is applied to a container ship, There is a possibility that the container loading amount is reduced, and an optimized arrangement structure is required.

At this time, the exhaust pipe 12 can pass through the second deck and the third deck between the gas turbine 11 and the upper deck.

However, the exhaust pipe 12 may be branched from the upper part of the upper deck to be connected to the waste heat recovering device or connected to the stack, and the branch point may be located at the upper part of the second deck at the lower part of the upper deck.

The heat recovery steam generator (HRSG) 15 may be provided on the upper deck in consideration of its own weight (about 100 tons). At this time, hatch coaming and a hatch cover are generally provided on the upper deck of the container line, but since the upper deck provided with the waste heat recovery device corresponds to the lower surface of the residence (or stack) And may not have a structure such as a hatch coaming. Therefore, the waste heat recovery apparatus can be stably supported at the upper portion of the upper deck.

Further, in order to prevent the loss of the load on the container (not shown) due to the installation of the waste heat recovery device, the waste heat recovery device may be horizontally disposed on the upper part of the upper deck and may be provided on the lower part of the housing . In other words, the waste heat recovering device can make the lengthwise direction of the hull to be in the width direction of the hull, thereby reducing the area occupied in the fore and aft direction while maximizing the width of the hull.

The waste heat recovering apparatus can generate steam by boiling water using waste heat (about 400 to 600 degrees or more) of the exhaust gas discharged from the gas turbine. At this time, the waste heat recovery apparatus can have a duct burner to secure additional heat, and the duct burner can heat the exhaust gas by using evaporative gas or the like used as fuel of the gas turbine 11. [

The waste heat recovery apparatus can supply the steam generated by the waste heat to the steam turbine, and recover the water condensed in the steam turbine. At this time, the condensed water, which is condensed water, can be converted to steam due to the waste heat of the exhaust gas of the gas turbine and can be supplied again to the steam turbine.

A switchboard room may be provided between a pair of steam turbine rooms.

However, the distance that a pair of gas turbine rooms are spaced apart from each other may be larger than the distance between the pair of steam turbine rooms. This is because the exhaust pipe extending from the gas turbine accommodated in the pair of gas turbine rooms extends toward the center of the hull and the exhaust flows to the center of the hull and the steam is collected by the waste heat recovering device provided in the width direction at the center of the hull, Because it is generated near the center.

A steam turbine (21) is installed inside the steam turbine room (20). The steam turbine room 20 is spaced apart from the exhaust pipe 12 and may be provided on the third deck or more so as to be provided above the gas turbine 11.
