Analysis of the Occurrence of Combustion Failure in the Steam Boiler at KM. Nggapulu

Abstract

The availability of steam is crucial for the smooth operation of devices requiring hot steam. The operational activities of a ship can be hindered if the production of hot steam is insufficient due to problems arising from inadequate maintenance or other reasons, leading to the failure of combustion in the steam boiler. This research aims to identify the factors influencing the failure of combustion in the steam boiler on KM Nggapulu, to understand the consequences of the combustion failure in the steam boiler on KM Nggapulu, and to ascertain the measures taken in the event of combustion failure in the steam boiler on KM Nggapulu. The research method employed in this thesis is qualitative. The data sources include primary and secondary data. Data collection techniques encompass observation, interviews, and documentation, ensuring the validity of the data. Based on the research conducted, the following conclusions can be drawn: The causes of combustion failure include irregular implementation of the Planned Maintenance System (PMS), contamination of main burner components (automizer, electrode, solenoid valve), clogged exhaust gas pipes due to soot, excessive air composition in the furnace due to exhaust gas pipe blockage, poor fuel quality, and irregular cleaning practices. The impacts of boiler combustion failure involve operational difficulties for systems dependent on hot steam, inadequate hot steam supply for passenger or crew accommodation, and viscosity issues in MFO (Marine Fuel Oil) due to inadequate hot steam. Remedial actions that can be taken include checking and maintaining the automizer, inspecting and maintaining the main burner (electrode and nozzle), cleaning the fuel heater, replacing the solenoid valve, reducing fuel viscosity, and cleaning the steam boiler exhaust gas duct.
