PURPOSE: A power plant for a ship with an SCR(Selective Catalytic Reduction) system and a secondary power generating system is provided to effectively recycle poisoned catalysts. CONSTITUTION: A power plant for a ship with a selective catalytic reduction system and an auxiliary power generating system comprises an engine(10), a main exhaust passage(61), an SCR reactor(30), a main valve(81), a secondary fuel cell(50), a temperature control passage(67), a temperature control valve(87), a supercharger(15), a scavenge receiver(19), a flow control passage(68), and a flow control valve(88). The engine is used as a main power source of the ship. The main exhaust passage exhausts the exhaust gas of the engine. The SCR reactor is installed on the main exhaust passage. The main valve is installed on the main exhaust passage between the engine and the SCR reactor. The secondary fuel cell is used to a secondary power source of the ship. The temperature control passage supplies the exhaust gas of the fuel cell to the SCR reactor. The temperature control valve is installed on the temperature control passage. The supercharger supplies air to the engine. The scavenge receiver relieves an uneven pressure of the air discharged from the supercharger. The flow control passage connects the scavenge receiver with the temperature control passage. The flow control valve is installed on the flow control passage. |
