Abstract:

At present,the appropriate way to account the NOX emission about thermal power sector is the method of emission factor.In order to determine NOX emission factor of thermal power units in China,it is necessary to do actual measurement among existing running thermal power units all over the county.How to determine sample’s number and scope scientifically presents its special importance during NOX emission factor research,because China has a large number of thermal power units which are very different in installed capacity levels.Acute determination of sample capacity of thermal power units is the premise of NOX emission factor research.The statistical method sampling is needed.In this paper,group sampling is employed taking constraints into consideration,including funds,installed capacity scale,end control technology (NOX control),fuel type and unit regional distribution.Sample capacity is adjusted and optimized under the constraints,and at last sample capacity for NOX emission factor of thermal power sector in China is determined as 208 sets
