Abstract

一种船舶储箱系统（1），带有容纳液态易燃燃料或备选地水的第一储箱、优选地第一燃料储箱（2），带有容纳气态不易燃燃料的第二燃料储箱（7），其中第二燃料储箱（7）互连或集成到第一储箱、优选地第一燃料储箱（2）中，使得第一储箱、优选地第一燃料储箱（2）在外侧包围第二燃料储箱（7）的至少区段。

Description

船舶储箱系统
技术领域
本发明涉及一种船舶储箱系统。
背景技术
双燃料马达在船舶上的使用在实践中是已知的。在双燃料马达中，液态易燃燃料（例如，柴油）可在第一操作模式中使用，且气态不易燃燃料（例如，天然气）可在第二操作模式中使用。在双燃料马达的第二操作模式中，通常将贫乏、不易燃的气体-空气混合物引入到马达的汽缸中，且由也引入到汽缸中的易燃的液态引燃流体的引燃能量引燃。
用于第一操作模式的液态易燃燃料容纳在第一燃料储箱中。气态不易燃燃料容纳在第二燃料储箱中，优选地呈液化形式。不同的燃料储箱需要许多安装空间。这是不利的，因为船舶上可用的安装空间是很有限的。
发明内容
从上文出发，本发明的目标在于产生新型的船舶储箱系统。此目标通过根据权利要求1的船舶储箱系统来实现。根据本发明，第二燃料储箱互连或集成到第一储箱（优选地第一燃料储箱）中，使得第一储箱（优选地第一燃料储箱）在外侧包围第二燃料储箱的至少区段。
集成或紧贴两个储箱显著地减小船舶储箱系统所需要的安装空间。于是，可最佳地利用船舶上可用的安装空间。
在本发明的进一步改进中，第一储箱（优选地第一燃料储箱）限定用于容纳液态燃料或水的储箱内部，其中第二燃料储箱的至少区段布置在第一储箱（优选地第一燃料储箱）的储箱内部的内侧，且由液态燃料或水包围。这也用于最佳地利用船舶上可用的安装空间。
在本发明的进一步改进中，第二燃料储箱具有圆柱形基部本体，其带有拱形端部区段，其中第二燃料储箱的拱形端部区段优选地在第一储箱（优选地第一燃料储箱）的立方形基部本体的壁上突出到第一储箱（优选地第一燃料储箱）外。气态燃料可简单地供给至第二燃料储箱或经由从第一容器（特别地第一燃料储箱）突出的第二燃料储箱的端部区段从后者移除。
在本发明的进一步改进中，第二燃料储箱的外壁与第一储箱（优选地第一燃料储箱）的壁紧密地连接（特别是焊接），第二燃料储箱在该壁上突出到第一储箱（优选地第一燃料储箱）外。特别地，这防止由第一燃料储箱容纳的液态燃料经由两个储箱之间的分界线不可控地逸出。
在本发明的进一步改进中，第二燃料储箱容纳呈液化形式的气态燃料。这是优选的，以便在第二燃料储箱中容纳尽可能多的气态燃料，给予后者最小可能的燃料储箱内部。
附图说明
本发明的优选的进一步改进可从从属权利要求和以下描述发现。将基于附图（而不限于其）更详细地解释本发明的示例性实施例。其上示出：
图1是穿过根据本发明的船舶储箱系统的截面。
具体实施方式
图1呈现构造为船舶燃料储箱系统的船舶储箱系统1的高度示意性的图示。在示出的示例性实施例中，船舶储箱系统1具有第一燃料储箱2，其提供燃料储箱内部20，该燃料储箱内部20容纳液态易燃燃料（例如，柴油或重质燃料或残油）。第一燃料储箱2典型地具有由壁定界的立方形几何形状。图1绘出此立方形的第一燃料储箱2的四个壁3, 4, 5和6。
船舶燃料系统[sic] 1还具有第二燃料储箱7，其容纳气态不易燃燃料（特别地天然气），特别是在第二燃料储箱7的燃料储箱内部21中。第二燃料储箱7优选地容纳在低温下呈液化形式的气态不易燃燃料。
在本发明的意义内，第二燃料储箱7紧贴或集成到第一燃料储箱2中，特别地使得第一燃料储箱2外部地包围第二燃料储箱7的至少区段。
如已解释的那样，第一燃料储箱2限定用于容纳液态易燃燃料的燃料储箱内部20。提供用于容纳液化的气态不易燃燃料的燃料储箱内部21的第二燃料储箱7的至少区段布置在第一燃料储箱2的燃料储箱内部20的内侧，且至少其区段由液态易燃燃料包围。图1呈现用于第一燃料储箱2的燃料储箱内部20中的液态易燃燃料的灌装线的示意图。
第二燃料储箱7具有圆柱形基部本体8，其带有拱形端部区段9和10。拱形端部区段9和10可设计为所谓的盘形底部或设计为所谓的3-中心弧底部（3-centered arc bottom）。图1呈现用于第二燃料储箱7的燃料储箱内部21中的液化的气态不易燃燃料的灌装线的示意图。
在图1上的优选示例性实施例中，用来容纳呈液化形式的气态不易燃燃料的第二燃料储箱7的拱形端部区段9在立方形的第一燃料储箱2的壁6处突出到第一燃料储箱2的燃料储箱内部20外。此壁6邻近所谓的连接空间19，与第一燃料储箱2或第二燃料储箱7相互作用的燃料线14, 15, 16在该连接空间19中被处理且连接至船舶的燃料供应系统的其他组件。
如可从图1发现的那样，两条燃料线14, 15（特别地燃料供给线14和燃料排出线15）注入第二燃料储箱7的燃料储箱内部21。图1还示出燃料线16，液态燃料可通过该燃料线16从第一燃料储箱2移除。
在示出的优选示例性实施例中，第二燃料储箱7设计为双壁的真空隔离的燃料储箱，其具有以后者的燃料储箱内部21为边界的内壁11以及包围内壁11的外壁12。
在其穿过第一燃料储箱2的壁6的位置中，第二燃料储箱7的外壁12与第一燃料储箱2的此壁6紧密地连接（特别是通过焊接），其中图1示出在第二燃料储箱7的外壁12与第一燃料储箱2的壁6之间对应的焊接接缝13，其由第二燃料储箱7的端部区段9穿过。
第二燃料储箱7经由支承脚17, 18安装在第一燃料储箱2的燃料储箱内部20中。第一支承脚17包括固定的支承，且第二支承脚18包括浮动的支承。结果，第二燃料储箱7固定地安装在第一燃料储箱2的燃料储箱内部20中。
因此，位于本发明的意义内的是至少部分地将用来容纳气态不易燃燃料的燃料储箱7集成到用来容纳流体的易燃燃料的燃料储箱2中，或使两个燃料储箱2, 7与彼此紧贴。
在这里用来容纳流体的易燃燃料的燃料储箱2外部地包围用来容纳优选地呈液化形式的不易燃气态流体的燃料储箱7（至少在区段中）。
以此方式集成或紧贴燃料储箱2, 7使得可能最佳地使用船舶上可用的安装空间。特别优选的是图1上示出的变型，其中用来容纳呈液化形式的气态不易燃燃料的燃料储箱7的一个端部区段9突出到用来容纳液态燃料的燃料储箱2外，特别是经由焊接与燃料储箱2的壁6（特别地与燃料储箱7的拱形区段9延伸通过的燃料储箱2的壁6）紧密地连接的其拱形端部区段9。
尽管在示例性实施例中绘出的储箱2是第一燃料储箱，但要注意的是，第一储箱2还可容纳水。于是，第一容器2不是燃料储箱，而是水储箱。
