The installed location of the unit is of equal importance to ensure low-cost ope
24、ration, ease of charging, ease of cleaning, and so forth. Consideration should be given to the following factors:a) maximum amount of each type of waste that will be incinerated each day (see Clause 5);b) normal number of hours per day that the incinerator will be in operation;c) loading procedure (
25、batch/continuous) over operating hours;d) if wet and dry material can be loaded into the incinerator, so that a large volume of auxiliary fuel is not requirede) if the incinerator can be installed on a ship in a location near the major source of refuse, so as to minimize the manpower requirements fo
26、r loading operations;f) if ashes will be removed easily if the incinerator is installed in the machinery space or on a lower deck;g) if ash removal will be manual (shovelling) or semiautomatic.5 Estimating daily quantities of solid waste to be incinerated Number of the ships crew:Galley and crew qua

31、he 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 w
32、aste 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 thei
33、r capacities and by the types of wastes they are capable of incinerating.7.1 Classification of shipboard wastesThe following classifications of shipboard waste differ from the definition of garbage as found in Annex V of MARPOL, which includes all of the types listed below.a) Type 0: Trash, a mixtur
34、e 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 r
35、ubber 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, an
36、d 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: Refus
37、e, 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
38、 and vegetable wastes from restaurants, cafeterias, galleys, sick bays, and like installations.This type of waste contains up to 70 % moisture, up to 5 % incombustible solids, and has a heating value of 5 800 kJ/kg as fired.e) Type 4: Aquatic life forms and animal remains, consisting of carcasses, o
39、rgans, and solid organic wastes from vessels carrying animal type cargoes.This type of waste contains up to 85 % moisture, 5 % incombustible solids, and has a heating value of 2 300 kJ/kg as fired.f) Type 5: By-product waste, liquid or semi-liquid, such as tar, paints, solvents, sludge oil, and so f
40、orth, from shipboard operations.BTU values shall be determined by the individual materials to be destroyed.g) Type 6: Solid by-product waste, such as rubber, plastics, wood waste, and so forth, from industrial operations.NOTE Energy values (kJ/kg or BTU/lb) has to be determined by the individual mat
41、erials to be destroyed. ISO 2014 All rights reserved 3BS ISO 18309:2014ISO 18309:2014(E)8 Incinerator operationsThe normal incineration procedure should be described for a vessel in the technical specification and waste management plan, to define how the incinerator is to be used under normal operat
42、ing conditions, and to make sure it has enough capacity for the intended use.Reports from tests performed to meet IMO MARPOL Annex VI or ISO 13617 emission requirements should be considered in capacity calculations.The sizing of the incinerator should take into consideration the expected daily opera
43、tional hours, the uncertainty in the calculation of the waste amount and the mixture of the waste. Also, sufficient time for repair and service of the incinerator should be taken into account.8.1 Solid waste capacity calculationFor solid waste generation, the values in Clause 5 should be considered.
44、It should be taken into account if the incinerator will be batch fed or has the capability to be sluice fed continuously, or a combination of both. Batch feeding reduces the daily capacity, since the chamber shall be cooled between batches before opening and reloading.8.2 Machinery sludge oil genera
45、tion calculationFor engines using heavy fuel oil (HFO), it can be estimated that about 1 % 2 % of the fuel consumption will end up in the sludge oil tank for incineration, depending on separator capabilities and operational procedures.The daily generation of sludge oil (SO, in litres) for two-stroke
46、 engines can also be estimated by the following formula:SO dailykWPCT()=()0 182 100 24,*/*hrswhere0,182 is a typical constant for two-stroke engines with units of litres/(kWhr);kW is the ship engine size in brake kW;PCT is the estimated sludge oil generation.The formula estimates the amount of sludg
47、e generated daily under 24 h transit. If engine size is in horsepower, divide result by 1,36. Suggested minimum PCT value is 1 or 2.If the main engine runs on MDO, the daily generation of sludge is limited, and sludge oil generation should be positively verified in each case.Other sources for sludge
48、 oil, such as lubricating oil and hydraulic oil, should also be added.8.3 Capacity calculation when burning both solid waste and sludge oilThe estimated capacity calculation should be the sum of the estimates generated by 8.1 and 8.2 above.The service tanks for sludge oil should at least have suffic
49、ient capacity to hold the daily generation of such waste, as defined by 8.2, received via the sludge oil holding tank.The flue gas extraction system shall have sufficient capacity to handle stack back pressure under all circumstances, to secure full effect of theoretical incinerator capacity, and to provide personnel and property protection.Back pressure calculations shall be presented and compared with system abilities.4 ISO 2014 All rights reservedBS ISO 18309:2014ISO 18309:2014(E)It is recommended to consult the equipment supp
