The Junior Combustion Engineer supports the design, testing, and optimization of fuel and combustion systems used in marine boiler applications, including auxiliary and propulsion boilers aboard commercial and naval vessels. This entry-level role works under the supervision of senior engineers to ensure proper burner performance, fuel efficiency, emissions compliance, and integration with broader steam and control systems.
Assist in the design and analysis of fuel delivery and burner systems for marine boilers using liquid or dual-fuel (LNG, MGO, HFO) configurations.
Conduct basic performance modeling, combustion calculations, and CFD analysis support for flame stability and heat release rates.
Support setup and execution of burner testing, including air/fuel ratio tuning, ignition reliability tests, and emissions monitoring.
Assist in reviewing component designs such as atomizers, air registers, and flame scanners for compatibility with fuel system layouts.
Help prepare technical documentation for system integration, including schematics, P&IDs, and fuel control logic.
Collaborate with control engineers and automation teams to interface combustion systems with boiler management systems (BMS).
Contribute to design reviews, hazard analyses, and safety checks related to combustion and fuel handling systems.
Assist in troubleshooting combustion-related field issues during commissioning or sea trials under supervision.
Combustion System Support: Learn and apply the fundamentals of burner operation, fuel system configuration, and emissions behavior.
Marine Boiler Integration: Gain exposure to the unique requirements of marine boilers and auxiliary heating systems.
Testing & Validation: Support lab or factory burner tests and analyze fuel system performance data.
Documentation: Assist in the development of fuel system schematics, control narratives, and technical reports.
Bachelor’s Degree in Mechanical Engineering, Marine Engineering, Energy Engineering, or related discipline.
0–3 years of experience or internship in combustion engineering, fuel systems, or thermal systems.
Basic understanding of combustion principles, fuel atomization, and emissions fundamentals.
Familiarity with fluid mechanics, thermodynamics, and heat transfer concepts.
Proficiency in Microsoft Office; familiarity with CAD and modeling tools (e.g., SolidWorks, ANSYS, or MATLAB) is a plus.
Strong written and verbal communication skills.
Exposure to marine systems, fuel bunkering, or boiler technologies (through academic projects or internships).
Basic knowledge of IMO MARPOL Annex VI, NOx/SOx limits, or Tier III emissions compliance.
Hands-on experience or coursework in combustion lab testing or CFD modeling.
