The invention discloses a ship LNG fuel cabin BOG processing system, and relates to the technical field of ship and ocean engineering, and the processing method comprises the following steps: 1, calculating the BOG quantity; step 2, checking parameters of the LNG dual-fuel boiler; 3, configuring a low-pressure compressor; 4, BOG heat exchanger configuration is calculated; and step 5, processing a result, calculating the quantity of BOG according to the cabin capacity and cabin pressure configured by the ship in the step 1, and checking parameters of the LNG dual-fuel boiler in the step 2, thereby obtaining a scheme capable of processing the quantity of generated BOG, a low-pressure BOG compressor and the dual-fuel boiler, a main engine cannot consume BOG, when the ship sails normally, the pressure in the cabin is gradually increased, and when the ship sails normally, the pressure in the cabin is gradually increased. BOG is pressurized through the low-pressure BOG compressor and then conveyed to the dual-fuel boiler to be burnt, generated steam is used for a public system of an original ship, and the system is simple in configuration, lowest in cost and minimum in occupied space.
本发明公开了一种船舶LNG燃料舱BOG处理系统,涉及船舶与海洋工程技术领域,其处理方法步骤如下:步骤一:BOG数量计算;步骤二:LNG双燃料锅炉参数核查;步骤三:低压压缩机配置;步骤四:计算BOG热交换器配置;步骤五:处理结果,所述步骤一中依据本船配置的舱容及舱室压力,计算出BOG数量,所述步骤二中核查LNG双燃料锅炉的参数,从而得出可以处理产生的BOG数量,低压BOG压缩机加双燃料锅炉方案,主机无法消耗BOG,当船舶正常航行时候,舱内压力逐步升高,使用低压BOG压缩机将BOG加压后输送至双燃料锅炉烧掉,产生的蒸汽用于原船的公用系统使用,本发明配置简单,成本最低,所占空间最少。
