7.16 Incinerator and Sludge/Waste Oil

Disposal System

Waste oil is a mixture of different types of oil (fuel oil and lubeoil) with a slight amount of water which is not suitable to beused for machineries.

It is being generated after treatment of drains collected fromdifferent oil tanks in the engine room.

Sludge is a semi-solid materials or waste left after the pre-treatmentprocess of waste water, fuel oil and lube oil onboard.

Both, waste oil and sludge are being burned to incinerator ordischarge to shore.

7.16.1 Incinerator

Incinerator is device used to burn solid and liquid trash andconvert into ashes and flue gases.

Incineration is a process used to reduce solid and liquid trashgeneration and helping to reduce pollutants in the sea.

Incinerator has good benefits for the personnel onboard asthe disposal of oily waste generated in the machinery spacesand combustible segregated trash as required by MARPOL

73/78, Annex V can be burned in the incinerator, therebyreducing accumulation and making the disposal procedureeasy.

7.16.2 Structure and Operating Principle

Main components Primary blower is used for cooling and combustion air.

Sludge burner is used to burn sludge/waste oil from the wasteoil tank and is made of pressure jet burner design withatomizing air.

Primary burner for primary combustion using diesel oil whenincinerating solid wastes.

Waste oil dosing pump for supply of waste oil to the burner.

Control Panel is provided for housing of electric controlequipment for automatic control.

Thermocouples for detecting high temperatures and alarm inprimary combustion chamber, and for detecting high flue gastemperature and alarm.
