Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described based on the drawings. In addition, the same code|symbol is attached|subjected to the common part in each figure, and overlapping description is abbreviate|omitted.

[0036] figure 1 It is the overall structure diagram of the energy recovery device 100 based on this invention.

[0037] In this figure, an energy recovery device 100 includes a supercharger line 10 , a power generation line 12 , an exhaust line 14 , a supercharger 20 , a power turbine generator 30 , and a control device 50 .

[0038] The supercharging line 10 , the power generation line 12 , and the exhaust line 14 are piping lines independently connected to the exhaust manifold M1 of the engine 1 .

[0039] Engine 1 is the main engine of the ship, in this example a diesel engine. Hereinafter, the engine 1 is simply referred to as a "main engine".

[0040] The load data of the engine 1 is input to the control device 50 in real time. A...

Abstract

This energy recovery device is provided with a supercharger (20), a power turbine electricity generator (30), and a control device (50). The power turbine electricity generator (30) is provided in an electricity generating line (12), and generates electricity by means of the energy of exhaust gas discharged from an exhaust manifold (M1). An electricity generation control valve (V1) is provided in the electricity generating line (12) to control the flow rate of the exhaust gas supplied from the exhaust manifold (M1) to the power turbine electricity generator (30). An exhaust valve (V2) is provided in an exhaust line (14) to vent exhaust gas from the exhaust manifold (M1) to the outside. The control device (50) controls the electricity generation control valve (V1) and the exhaust valve (V2).

Description

technical field [0001] The present invention relates to an energy recovery device capable of responding to the third regulation of NOx, its control method, and a ship equipped with the same. Background technique [0002] The IMO regulations on air pollutants discharged from ships have become stricter year by year, and in the third NOx regulation (NOx Tier III, hereinafter referred to as the third regulation), a value higher than that of the first regulation was given. Cut obligations by 80%. [0003] In order to cope with this third regulation, an exhaust gas recirculation device (Exhaust Gas Recirculation: hereinafter referred to as EGR) may be employed as a denitrification device of a diesel main engine. [0004] However, ships equipped with EGR generate a large amount of excess exhaust gas in sea areas where the third regulation is not applied (non-restricted sea areas), and energy efficiency decreases. [0005] Therefore, Patent Document 1 is disclosed, for example, as...
