PM CEMS Wet Stack 181 · Measuring Particulate Emissions from Wet Scrubbers
The system uses an advanced ProScatterTM light scatter sensor (PCME QAL 181) which is certified by TUV and MCERTS as QAL1 compliant. With certification ranges covering both 0-15 mg/m3 and 0-100 mg/m3 dust levels, the sensor is suitable for monitoring the highly abated emissions found after Flue Gas Desulphurisation Plant (FGD). The instrument is able to monitor a saturated flue gas which is critical for the application of monitoring emissions from a coal fired power plant fitted with a wet FGD system and meets the requirements of PS-11 and EN 14181.
The system will also operate reliably in the flue gas conditions found after wet collectors in the Pulp and Paper, Metal and Chemicals industry where particulate levels are higher and the instrument is able to cope with potentially more contaminating conditions.
Key advantages of the instrument are as follows: • Highly sensitive (<0.1 mg/m3) and rugged instrument for measuring particulate • Isokinetic condition automatic adjustment [requires input from external flow meter (option) • Automatic control and function test of all critical systems (vaporising chamber, • Low maintenance requirements and no laborious service requirements • Modular design to facilitate lifting to stack location and ease of assembly • QAL1 approved light scatter probe, suitable for monitoring according to • Automatic zero and span drift check and manual audit functionality • Powerful user interface and in built data logging and recording Isokinetic Sampling (option)
