11 Example of an on-board system for oil sludge incineration

  11.1 General

  • 11.1.1 In addition to the provision of sludge tanks, another means for the disposal of oil residue (sludge) are oil sludge incinerators.

  11.2 Oil sludge incinerators

  • 11.2.1 An oil sludge incinerator system is composed of:

    • steam boiler or heater of thermal fluid systems or an incinerator;
    • oil burner;
    • oil sludge processing system; and
    • tanks for separated sludge.

  11.3 Oil sludge processing systems

  • 11.3.1 The oil sludge processing system consists of:

    • tank for mixing oil residues with fuel oil (mixing tank);
    • oil sludge preheating system;
    • filter; and
    • homogenization system.

  11.4 Mixing tank

  • 11.4.1 The mixing tank should be provided in addition to the tank for separated sludge. It should be equipped with suitable drainage facilities. With a view to improving combustibility and calorific value, a fuel oil supply connection should be provided.

  11.5 Homogenization system

  • 11.5.1 The homogenization system should assure that the entire contents of the mixing tank should be processed into a homogenous and combustible mixture. This system should be put into operation, following adequate draining of the tank. A device for continuous indication and monitoring of the water content of the oil sludge should be provided.
