3.9
maintenance waste
materials collected by the engine department and the deck department while maintaining and operating the vessel, such as soot, machinery deposits, scraped paint, deck sweeping, wiping wastes, oily rags, etc.
3.10
operational wastes
all cargo-associated wastes and maintenance waste (including ash and clinkers), and cargo residues defined as garbage (3.7)
3.11
oily rags
rags which have been saturated with oil as controlled in annex I to MARPOL 73/78
3.12
plastic
a solid material which contains, as an essential ingredient, one or more synthetic organic high polymers and which
is formed (shaped) during either manufacture of the polymer or the fabrication into a finished product by heat
and/or pressure
NOTE Plastics have material properties ranging from hard and brittle to soft and elastic. Plastics are used for a variety of marine purposes including, but not limited to, packaging (vapour-proof barriers, bottles, containers, liners), ship construction (fibreglass and laminated structures, siding, piping, insulation, flooring, carpets, fabrics, paints and finishes, adhesives, electrical and electronic components), disposable eating utensils and cups, bags, sheeting, floats, fishing nets, strapping bands, rope and line.
3.13
ship
a vessel of any type whatsoever operating in the marine environment and including hydrofoil boats, air-cushioned
vehicles, and submersibles, floating craft and fixed or floating platforms
3.14
sludge oil
sludge from fuel and lubricating oil separators, waste lubricating oil from main and auxiliary machinery, waste oil from bilge water separators, drip-trays, etc.
3.15
waste
useless, unneeded or superfluous matter, which is to be discarded
4 General design requirements
4.1 Piping
Piping for fuel and sludge oil shall be constructed of seamless steel of adequate strength and to the satisfaction of the Administration. Short lengths of steel, or annealed copper nickel, nickel copper, or copper pipe and tubing may be used at the burners. The use of non-metallic materials for fuel lines is prohibited. Valves and fittings may be threaded in sizes up to and including 60 mm outer diameter, but threaded unions are not to be used on pressure lines in sizes 33 mm outer diameter and over.
4.2 Rotating parts
All rotating or moving mechanical and exposed electrical parts shall be protected by guards or shields against accidental contact by personnel in the vicinity of the incinerator.
4.3 Insulation and cooling
4.3.1 Incinerator walls are to be protected with insulated fire bricks/refractory and a cooling system. The outside surface temperature of the incinerator casing being touched during normal operations shall not exceed 20 °C above the ambient temperature.
4.3.2 The refractory shall be resistant to thermal shocks and resistant to normal ship’s vibration. The refractory design temperature shall be equal to the combustion chamber design temperature plus 20 % (see 4.12).
4.3.3 The outside surface of combustion chamber(s) shall be shielded from contact such that personnel will not be exposed to extreme heat of more than 20 °C above the ambient temperature, or direct contact with surface temperatures exceeding 60 °C.
EXAMPLE 1 Double jacketing with an air space between jackets
EXAMPLE 2 Expanded metal jacketing
4.4 Corrosion
Incinerating systems shall be designed such that corrosion will be minimized on the inside of the systems.
4.5 Liquid waste incineration
In systems equipped for incinerating liquid wastes, safe ignition and maintenance of combustion shall be ensured,
e.g., by a supplementary burner using gas oil/diesel oil or equivalent.
4.6 Combustion chamber
The combustion chamber(s) shall be designed for easy maintenance of all internal parts including the refractory and insulation.
4.7 Combustion pressure
The pressure in the furnace under all circumstances shall be lower than the ambient pressure in the space where the incinerator is installed to ensure that the combustion process takes place under negative pressure. A flue gas fan may be fitted to provide negative pressure.
4.8 Charging solid waste
The incinerating furnace may be charged with solid waste either by hand or automatically. In every case, fire dangers shall be avoided and charging shall be possible without danger to the operating personnel.
EXAMPLE 1 Where charging is carried out by hand, a charging lock could be provided which ensures that the charging space is isolated from the fire box as long as the filling hatch is open.
EXAMPLE 2 Where charging is not effected through a charging lock, an interlock could be installed to prevent the charging door from opening while the incinerator is in operation with burning of garbage in progress, or while the furnace temperature is above 220 °C.
4.9 Feeding system
Incinerators equipped with a feeding sluice or system shall ensure that the material charged will move to the combustion chamber. Such systems shall be designed such that both the operator and environment are protected from hazardous exposure.
