Fire extinguishing system

Abstract

The invention relates to a fire extinguishing system for a marine vessel comprising an engine room (1) and a fuel cell arrangement. In order to improve the fire extinguishing system with respect to the fuel cell arrangement comprising at least one fuel cell module (2), the fuel cell module (2) is provided with at least one fire detection sensor (9) and at least one internal nozzle (10) for releasing a fire extinguishing medium into the fuel cell module.

Description

technical field [0001] The invention relates to a fire extinguishing system for a marine vessel comprising an engine room and a fuel cell assembly according to the preamble of claim 1 . Background technique [0002] Fire extinguishing systems are generally required in engine rooms or machine rooms of marine vessels or other marine structures, such as drilling platforms and liquefied natural gas stations. The fire suppression system is generally designed for the entire engine room CO 2 system. In addition, the so-called prime movers must be provided with a local fire extinguishing system. In practice, this means that the water mist spraying device is placed above the engine or other machinery and equipment. [0003] CO 2 The system is effective, but cannot be used until the entire engine room is emptied, i.e. all personnel are evacuated. This usually means delayed release of CO 2 , which increases the destructiveness of the fire. To ameliorate this situation requires t...

AI Technical Summary

Problems solved by technology

In the event of a fire, the main CO in the engine room 2 Undesirable delays in the system and increased damage to fuel cell components

Additionally, the CO released by the engine room around the fuel cell components 2 role is not enough

In addition, traditional localized fire suppression systems involving water mist are not suitable for electrical components because of the risk of short circuits that could lead to damage to fuel cell components
