SOLAS是这么要求的：
Chapter II-2: Construction – fire protection, detection, extinction
Regulation 7
5.5 Cargo ships
Accommodation and service spaces and control stations of cargo ships shall be protected by a fixed fire
detection and fire alarm system and/or an automatic sprinkler, fire detection and fire alarm system as
follows, depending on a protection method adopted in accordance with regulation 9.2.3.1.
5.5.1 Method IC – A fixed fire detection and fire alarm system shall be so installed and arranged as to provide
smoke detection in all corridors, stairways and escape routes within accommodation spaces.
5.5.2 Method IIC – An automatic sprinkler, fire detection and fire alarm system of an approved type
complying with the relevant requirements of the Fire Safety Systems Code shall be so installed and arranged
as to protect accommodation spaces, galleys and other service spaces, except spaces which afford no
substantial fire risk such as void spaces, sanitary spaces, etc. In addition, a fixed fire detection and fire alarm
system shall be so installed and arranged as to provide smoke detection in all corridors, stairways and escape
routes within accommodation spaces.
Chapter II-2: Construction – fire protection, detection, extinction
Regulation 9
7.5 Exhaust ducts from galley ranges
7.5.2 Requirements for cargo ships and passenger ships carrying not more than 36 passengers
7.5.2.1 Where they pass through accommodation spaces or spaces containing combustible materials, the
exhaust ducts from galley ranges shall be constructed of ‘‘A’’ class divisions. Each exhaust duct shall be fitted
with:
.1 a grease trap readily removable for cleaning;
.2 a fire damper located in the lower end of the duct;
.3 arrangements, operable from within the galley, for shutting off the exhaust fans; and
.4 fixed means for extinguishing a fire within the duct.
可见公约并没有规定喷嘴数量。喷嘴数量和喷嘴的形式，厨房风道所需要的CO2容量都有关系，不是简单的一个两个就可以解释的。厨房风道的CO2可以认为是一个火星熄灭装置。 |

楼主
11L的辛苦了。CO2喷嘴数量在SOLAS上好像真没有原文提到。但是船检应该有自己的理解。我们厂这边也是配了两个。但是我觉得应该一个喷嘴在靠近集气罩端，一个喷嘴在靠近防火风闸端。主要是消除这段干管内的火焰，防止火焰影响到其他处所。但是实船我们厂的工人全装在集烟罩上方的抽烟干管分支上了。但是船检也没提，所以就这么着了。
