ANNEX VTechnical provisions relating to combustion plants

PART 2Emission limit values for combustion plants referred to in Article 30(3)

1.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.

In case of combined cycle gas turbines with supplementary firing, the standardised O2 content may be defined by the competent authority, taking into account the specific characteristics of the installation concerned.

5.Gas turbines (including CCGT) using light and middle distillates as liquid fuels shall be subject to an emission limit value for NOx of 50 mg/Nm3 and for CO of 100 mg/Nm3

Gas turbines 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.

6.Emission limit values (mg/Nm3) for NOx and CO for gas fired combustion plants

a

For single cycle gas turbines having an efficiency greater than 35 % – determined at ISO base load conditions – the emission limit value for NOx shall be 50xη/35 where η is the gas turbine efficiency at ISO base load conditions expressed as a percentage.

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

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.
