2.2 Feeding and Charging
Controlled hygienic mechanical feeding that does not negatively influence the air temperature in the primary and secondary chambers of the incinerator shall be used.
2.3 Primary Combustion Chamber.
a) This chamber should be equipped with burners that use low sulphur fuel.
b) The chamber should ensure a minimum exit temperature of 850 degrees centigrade.
2.4 Secondary Combustion Chamber (After burner)
a) Should be fitted with burners that use low sulphur fuel.
b) Ensure secondary air supply is controlled.
c) Ensure residence time is not less than two seconds.
d) Ensure that the gas temperature as measured against the inside wall in the secondary chamber and not in the flame zone is not less than 1100 degrees centigrade.
e) Ensure the emitted oxygen content of the emitted gases is not less than 11%
f) Ensure both primary and secondary combustion temperatures are maintained until all waste is completely combusted.
