   packing materials.
2. Polychlorinated biphenyls (PCBs)
3. Garbage, as defined in Annex V of the present Convention, containing more than traces of heavy metals; and refined petroleum products containing halogen compounds
4. Incineration of sewage sludge and sludge oil generated during the normal operation of a ship

Question 17

must be monitored and should not be less than 850 deg C for continuous feed and reach 600 deg C within 5 minutes ( time may vary depending upon the capacity of incinerator) for a batch feed

Answer 17

Flue Gas Temperature

Answer 18

Not less than 850°C

Question 19

The Flue Gas Temp of the Batch Feed should reach how much?

Answer 19

600°C within 5 mins

Question 20

During incineration, it is important to control the exhaust temperature, which should not be very high or too low.

Answer 20

Incinerator Exhaust Gas Temperature

Question 21

could lead to melting of metal and can cause damage to the machinery

Answer 21

High Incinerator Exhaust Gas Temperature

Question 22

not be able to burn the residue and sterilise and remove odour from the residue

Answer 22

Low Incinerator Exhaust Gas Temperature
