Abstract

To provide a boiler system for burning BOG discharged from a free flow line depending on a discharge amount while enabling heat recovery.SOLUTION: A boiler system 1 is mounted on a vessel including a liquefied gas storage tank T1, and a free flow line 2A for distributing BOG generated in the liquefied gas storage tank T1. The boiler system 1 includes at least, a boiler 10 for burning the BOG flowing in the free flow line 2A, a gas fuel flow amount adjustment part 3 for adjusting the flow amount of gas fuel to be supplied to the boiler 10, a BOG supply line 2B connected to the downstream side of the free flow line 2A for supplying the BOG to the boiler 10, a BOG pressure detection part 11 arranged on the upstream side of the gas fuel flow amount adjustment part 3 for detecting a BOG pressure Pg in the BOG supply line 2B, and a control part 14 for controlling the gas fuel flow amount adjustment part 3 on the basis of the detection result of the BOG pressure detection part 11.SELECTED DRAWING: Figure 1
