22、itoring of emissions at stationary sources as an alternative and/or backup for automated measuring systems (AMS). PEMS define the relationship between a number of characteristic process parameters of an emission source and the corresponding emission concentration. If the characteristic process param

23、eters are continuously monitored it is possible with a PEMS to continuously determine the emission concentration of the emission source.PEMS are deduced using process data and, where required, emission data from the emission source. Using these data the PEMS is modelled. PEMS contains an emissions m

24、odel and a sensor validation system for quality assurance of incoming process data.PEMS are plant-specific emission monitoring systems and vary as regards to methodology and design: relational models (emission concentration as a function of one or more process parameters): theoretical or empirical r

25、elations that are fitted to a plant-specific emission data set; nonlinear statistical models, e.g. neural network models, or other multiple regression techniques.Where a component or process is specifically stated, the reference is provided as an example.The range of application of PEMS is limited t

26、o plants with well-defined fuels and operating conditions, using inherent emission control systems. If multiple fuels are used all fuel variations are reflected in the emission model. Using inherent emission control systems means not having a downstream emission abatement system.PEMS is illustrated

27、in Figure 1. It consists of: PEMS software, which is certified according to an EN 15267 procedure, with the exceptions stated in this Technical Specification; PEMS emissions model, which is documented by a QAL1 and validated by a QAL2 procedure according to EN 14181, with the exceptions stated in th
