  • 1. INCINERATOR AND MARPOL REQUIREMENTS Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 2. The rules governing the operation of INCINERATOR is MARPOL Annex VI. MARPOLAnnex VI: “Regulations for the Prevention of Air Pollution from Ships”. Regulation 16: “Requirements for the control of emission from ships”
  • 3. Regulation 16 : Emissions from shipboard incinerators Incinerators installed after 1st Jan 2000 to meet regulations and must certified to meet the specifications in MEPC Resolution 76(40) (Appendix IV of Annex VI). Each incinerator must have a manufacturers operations manual. Crew responsible for the incinerator operation shall be trained and follow the operations manual. 36/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 4. Regulation 16 : Emissions from shipboard incinerators  The following substances are prohibited from incineration: Annex I, II and III cargo residues and related packing material. PCBs. Garbage as defined by Annex V containing heavy metals. Petroleum Products containing halogens.  PVC can only be incinerated in type approved incinerators.  Flue gas temperatures shall be monitored and not less than 850 deg C for continuous feed and reach 600 deg C within 5 minutes for batch feed. 46/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 5. 5 INCINERATORS On Board incineration is not just for waste oil and sludge. They can also be used for Garbage such as food, paper, cardboard and wood. However Garbage is its own little topic within MARPOL and that will be discussed later on. They can also be used for the disposal of SEWAGE which again is its own topic within MARPOL 6/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 6. 6 INCINERATORS For disposal of sludge residue generated from fuel or lub oil operations, the sludge residue may be burnt on its own, or may be the main fuel for burning other materials. This will depend entirely on its water content. 6/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 7. 7 INCINERATORS Incineration combustion processes do not generate heat for any useful work and the exhaust gases are not suitable for any type of cargo inerting process. Fuels used in the incinerator are carbon rich, and with sufficient air supply will generate extremely high temperatures. Large amounts of excess air are supplied to the process in order to cool the incinerator and dilute the products of combustion. Air is supplied to combustion via a typical forced draught fan, whilst a large induced fan in the flue induces excess air to cool the incinerator double skinned walls, prevent fumes escaping from combustion and cool and dilute the discharged flue gases. 6/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 8. 8 INCINERATORS Typical incinerator features include: Heavy-duty all welded construction with high strength, durable castable high temperature refractory lining Fully automatic electrical controls with simple and reliable operation Single batch or continuous waste loading May be in Vertical and horizontal design, plus modular construction for easy installation Full swing combustion chamber door for total access 6/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 9. 9 INCINERATORS Typical incinerator features include: Liquid waste dam and auto loading systems Class and USCG approval for shipboard use according to MARPOL Annex VI & MEPC.76(40) 6/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
  • 10. 10 INCINERATORS In normal operation , the incinerator start up procedure involves firing the incinerator on MDO, ensuring that a vacuum is ”pulled” on the exterior skin, loading waste, and monitoring combustion. When combustion is well established sludge burning may be attempted. Sludge is prepared by heating circulating and draining of any excess water. Sludge is introduced and is burnt with fuel for a period of time until combustion is well established. Fuel is then shut off, and sludge is burnt alone Excess water in the sludge may cause combustion temperature to fall, in which case fuel burning recommences. 6/9/2014 Mohd. Hanif Dewan, Chief Engineer and Maritime Lecturer & Trainer, Bangladesh.
