IPPC, Annexes V, VI, VIII - Provisions relating to industrial plants

This database contains emission limit values for polluting substances in waste gases and waste water, assigned according to facility type (i.e., combustion plants (Annex V), waste incineration/co-incineration plants (Annex VI), and installations producing titanium dioxide (Annex VIII)), under Directive 2010/75/EU on Industrial Emissions (Integrated Pollution Prevention and Control - IPPC).

Point
6
Notes
00 All emission limit values shall be calculated at a temperature of 273,15 K, a pressure of 101,3 kPa and after correction for the water vapour content of the waste gases and at a standardised O2 content of 6 % for solid fuels, 3 % for combustion plants, other than gas turbines and gas engines using liquid and gaseous fuels and 15 % for gas turbines and gas engines

04 75 mg/Nm3 in the following cases, where the efficiency of the gas turbine is determined at ISO base load conditions: (i) gas turbines, used in combined heat and power systems having an overall efficiency greater than 75 %; (ii) gas turbines used in combined cycle plants having an annual average overall electrical efficiency greater than 55 %; (iii) gas turbines for mechanical drives

05 For single cycle gas turbines not falling into any of the categories mentioned under note (2), but having an efficiency greater than 35 % - determined at ISO base load conditions - the emission limit value for NO x shall be 50xɳ/35 where ɳ is the gas turbine efficiency at ISO base load conditions expressed as a percentage

06 Natural gas is naturally occurring methane with not more than 20 % (by volume) of inerts and other constituents

07 For gas turbines (including CCGT), the Nox and CO emission limit values set out in the table contained in this point apply only above 70 % load

08 For gas turbines (including CCGT) which were granted a permit before 27 November 2002 or the operators of which had submitted a complete application for a permit before that date, provided that the plant was put into operation no later than 27 November 2003, and which do not operate more than 1 500 operating hours per year as a rolling average over a period of 5 years, the emission limit value for NOx is 150 mg/Nm3 when firing natural gas and 200 mg/Nm 3 when firing other gases or liquid fuels

16 Gas turbines and gas engines for emergency use that operate less than 500 operating hours per year are not covered by the emission limit values set out in this point. The operator of such plants shall record the used operating hours
