legislation the emission limit value for NOx does not apply to plants only incinerating hazardous waste

Directive  2000/76/EC  of  the  European  Parliament  and  of  the  Council  of  4 December 2000 on the incineration of waste.

Exemptions for NOx may be authorized by the competent authority for existing incineration plants:

  with a nominal capacity of 6 tonnes per hour, provided that the

permit foresees the daily average values do not exceed 500 mg/m3 and this until 1 January 2008,

    with a nominal capacity of >6 tonnes per hour but equal or less than 16 tonnes per hour, provided the permit foresees the daily average values do not exceed 400 mg/m3 and this until 1 January 2010,

    with a nominal capacity of >16 tonnes per hour but <25 tonnes per hour and which do not produce water discharges, provided that the permit foresees the daily average values do not exceed 400 mg/m3 and this until 1January 2008.

 

Until 1 January 2008, exemptions for dust may be authorized by the competent authority for existing incinerating plants, provided that the permit foresees the daily average values do not exceed 20 mg/m3.

 

Since, Hydrogen chloride (HCl), Hydrogen fluoride (HF) , Sulphur (S) are not present in feed so, these will not be present in flue gas.

Until 1 January 2010, exemptions for NOx may be authorized by the competent authority for existing incineration plants with a nominal capacity between 6 and 16 tonnes per hour, provided the half-hourly average value does not exceed 600 mg/m3 for column A or 400 mg/m3 for column B.

These average values cover also gaseous and the vapour forms of the relevant heavy metal emissions as well as their compounds.

 

(d)   Average values shall be measured over a sample period of a minimum of 6 hours and a maximum of 8 hours.

 

The emission limit value refers to the total concentration of dioxins and furans calculated using the concept of toxic equivalence in accordance with Annex I.

 

Dioxins and furans  = 0,1 ng/m3

 

(e)   The following emission limit values of carbon monoxide (CO) concentrations shall not be exceeded in the combustion gases (excluding the start-up and shut- down phase):

 

  50 milligrams/m3 of combustion gas determined as daily average value;

   150 milligrams/m3 of combustion gas of at least 95 % of all measurements determined as 10-minute average values or 100 mg/m3 of combustion gas of all measurements determined as half-hourly average values taken in any 24- hour period.

 

Exemptions may be authorized by the competent authority for incineration plants using fluidized bed technology, provided that the permit foresees an emission limit value for carbon monoxide (CO) of not more than 100 mg/m3 as an hourly average value.
