The basis for satisfactory incinerator operation is the correct analysis of the waste to be destroyed and the selection of proper equipment to best destroy that particular waste.
As a guide, mixtures of waste most commonly encountered have been classified into types of waste,together with the heat content (kJ/kg) values and moisture contents of the mixtures. For example, a concentration of one specific waste in the mixture may change the heat value or the moisture content, or both, of the mixture. A concentration of more than 10 % by weight of catalogues, magazines, or packaged paper will change the density of the mixture and affect burning rates.
Similarly, incinerators have been classified by their capacities and by the types of wastes they are capable of incinerating.
The following classifications of shipboard waste differ from the definition of garbage as found in AnnexV of MARPOL, which includes all of the types listed below.
a) Type 0: Trash, a mixture of highly combustible waste, such as paper, cardboard, cartons, wood boxes, and combustible floor sweepings from commercial and industrial activities. The mixtures contain up to 10 % by weight of plastic bags, coated paper, laminated paper, treated corrugated cardboard, oily rags, and plastic or rubber scraps.
This type of waste contains 10 % moisture, 5 % incombustible solids, and has a heating value of 19 730 kJ/kg as fired.
b) Type 1: Rubbish, a mixture of combustible waste, such as paper, cardboard cartons, wood scrap,foliage, and combustible floor sweepings, from domestic, commercial, and industrial activities. The mixture contains up to 20 % by weight of galley or cafeteria waste, but contains little or no treated papers, plastic, or rubber wastes.
This type of waste contains 25 % moisture, 10 % incombustible solids, and has a heating value of 15 100 kJ/kg as fired.
c) Type 2: Refuse, consisting of an approximately even mixture of rubbish and garbage by weight.
This type of waste is common to the occupancy of the passenger ships, consisting of up to 50 % moisture, 7 % incombustible solids, and has a heating value of 10 000 kJ/kg as fired.
d) Type 3: Garbage, consisting of animal and vegetable wastes from restaurants, cafeterias, galleys,sick bays, and like installations.ISO 18309 pdf free download.
