这是瓦锡兰LNG双燃料发动机安装指南的内容。rupture discs,一种泄压装置,翻成中文应该是“爆破片”吧。
Relief devices - rupture discs
Explosion relief devices such as rupture discs are to be installed in the exhaust system. Outle
are to discharge to a safe place remote from any source of ignition. The number and locati
of explosion relief devices shall be such that the pressure rise caused by a possible explosi
cannot cause any damage to the structure of the exhaust system.
This has to be verified with calculation or simulation. Explosion relief devices that are locat
indoors must have ducted outlets from the machinery space to a location where the pressu
can be safely released. The ducts shall be at least the same size as the rupture disc.The duo
shall be as straight as possible to minimize the back-pressure in case of an explosion.
