Working Principle of a Marine Incinerator

 

Step-by-Step Operation Principle

 

Preparation and Ignition: The combustion chamber is heated to the desired temperature using the auxiliary/main burner. Diesel fuel is supplied to the main burner to initiate the ignition process. Once the combustion chamber is sufficiently hot, the sludge oil or solid waste is introduced. After the waste is ignited, the main burner can be shut down automatically or manually.

 

Primary Combustion: The waste oil or solid waste is burned in the main combustion chamber. Atomizing air is supplied to the sludge burner for efficient combustion. A blower provides a steady supply of combustion air.

 

Secondary Combustion: The exhaust gases from the main combustion chamber are directed to the secondary combustion chamber. These gases are maintained at a high temperature and completely burned to eliminate pollutants. A refractory lining (usually ceramic) separates the two combustion chambers.

Monitoring and Safety: The process is regulated by automatic controls that monitor temperature. Safety interlocks are in place, such as a switch that shuts off the burner when the loading door is opened. If the temperature drops below a minimum threshold, an alarm sounds and the system may shut down to prevent improper combustion. Regulations also require that flue gas temperatures meet certain standards (e.g., not exceeding 350°C), and the system is monitored for overheating.
