3 Terms and Definitions
The following terms and definitions apply in this standard.
3.1 Thermal power plant
The power plant firing solid, liquid or gas fuels.
3.2 Standard condition
The state where the flue gas is 273K in temperature and 101325 Pa in pressure for short as "SC". For the purpose of this national standard, the emission concentration of the air pollutant refers to the value of dry flue gas under standard condition.
3.3 O2 content
The spare free oxygen contained in the flue gas when the fuel is burning expressed usually with dry basis volume percentage.3.4 Existing plant
The plants which has been constructed and put into operation or the environmental impact assessment document of which has been examined and approved before the implementation date of this standard.
3.5 New plant
The newly-built, expanded and rebuilt plants of which environmental impact assessment document has been examined and approved before the implementation date of this standard.
3.6 Arch fired furnace
It refers to the arch fired combustion space formed where the burner is placed in front and back arch crowns of the furnace, the fuel and air eject downwards and the combustion products discharge upwards from the middle of the front and back arches after they deflect 180°.
3.7 Key region
It refers to the regions, in accordance with the requirements of the environmental protection, where the land development density is higher and environment bearing capacity starts to be weaken or those where the atmospheric environment capacity is smaller, the ecological environment is vulnerable and the air pollutants discharge shall be controlled strictly as required by the serious incidental atmospheric environment pollutions.
3.8 Special limitation for air pollutants
It refers to the air pollutants limitation formulated and implemented in order to prevent and treat the regional atmosphere pollution, improve environmental quality, reduce further discharge strength of atmospheric pollution sources, control more strictly pollution discharge behaviors; this limitation's emission control level has reached the international advanced or leading degree and applicable to the key regions.
