Performance measurement is undertaken for any of the following three purposes:
• Establishing initial or periodic compliance with performance standards (e.g., trial burns)
• Routine monitoring of process performance and direct process control (e.g., continuous monitoring)
• Conducting performance measurements for research and equipment development
Figure 11.14.7 illustrates sampling points for assessing incinerator performance. In trial burn activities, sampling activities focus on collecting of waste feed and stack emission samples. Ash and air pollution control system residues are also sampled and analyzed. Sampling of input and out put around individual unit components, e.g. scrubbers, may also be conducted in research or equipment evaluation studies.
