In compliance with Annex VI of the MARPOL 1973/78 Convention of the IMO, which aims to prevent air pollution from ships, it is essential to strictly adhere to the guidelines for the storage and disposal of waste at sea. 

Incinerating various materials such as galley waste, food scraps, accommodation waste, linen, cardboard, oil sludge from lubricating oil, fuel oil, bilge and purifier, sewage sludge, etc. is considered one of the most effective methods for waste disposal and for conserving the storage capacity of the ship and waste storage containments. Additionally, the residue left from the incineration mainly consists of ash, making it easier to dispose of.

For any foreign-going vessels, an onboard incinerator installed on or after 1 January 2000 must adhere to the standard specifications for shipboard incinerators developed under resolutions.

Types of Marine Incinerators

Vertical cyclone and horizontal burner are the two most commonly used incinerator types on a ship.

Vertical Cyclone Type ON Board M.V. SEAFDEC

In this type of incinerator, the burner is mounted on the top and the waste to be incinerated is introduced into the combustion chamber from above. A rotating arm device is provided to enhance combustion and remove ash and non-combustibles from the surface. The important parts of the incinerator include.

The important parts of the incinerator are:

1.Combustion chamber with diesel oil burner, sludge burner, pilot fuel heater, and electric control panel.

2.Flue gas fan which may be fitted with a flue gas damper or frequency inverter.

3.Sludge service tank with a circulating pump and heater.

4.Sludge settling tank with filling pump and heater (Optional).

5.Water injection (Optional).

6.Use a rotating arm to remove ash and non-combustibles (applies to vertical cyclone type)
