AI Technical Summary

Technical Problem

Impurities in marine fuel can cause blockages in the gas supply system, affecting the normal operation of the engine, increasing maintenance costs and safety hazards. Furthermore, the quality of fuel varies greatly in different regions, making management difficult.

Method used

Design a dual-fuel gas supply system, including a fuel tank, a sedimentation and cleaning tank, a filter module, and a multi-stage filtration system. Through multi-stage filtration and nitrogen purging, ensure that impurities are effectively removed from the fuel before it enters the main unit. The multi-stage filtration system, consisting of filter mesh plates and nitrogen purging, achieves efficient and clean fuel supply.

Benefits of technology

Effectively removes impurities from fuel, ensuring system reliability, extending equipment life, ensuring safe and efficient ship operation, reducing maintenance costs, and ensuring safe and efficient ship operation during navigation. It also reduces the need for nitrogen to be converted to fuel oil, ensuring smooth operation of the dual-fuel gas supply system, extending equipment life, and guaranteeing safe and efficient ship operation.
