DioxinMonitoringSystem® is a device, which has been developed
for continuous monitoring of dioxin emissions.
The design furter offers versatile application for the sampling of other pollutants, like e.g. PCBs, metals, HCB, etc.
The design and the use of the dilution method offer versatile and represen- tative applications, like
sampling of organic pollutants (e.g. PCBs, metals, HCB) and fine dust (PM10, PM2.5).
The results of the measurements are the average gas concentrations
of the sampling period, statistically weighted by the gas flow.
Because all the dust is sampled into the cartridge, the dust
can be weighted and analysed to achieve additional information.
Ssamples from the stack show the pollution situation
directly from the source. Dependent on the operating conditions, peak emissions
of the plant, especially on dioxin and PCB emissions, can show high variations.
The DioxinMonitoringSystem® was developed to measure representative
mean values and it is designed for long term sampling of 6 weeks.
It fulfils all the requirements of the dioxin measurement standard EN
1948-1. A stand-by-logic enables the configuration of automatic start/stop, in case of plant stops and restarts. Two probes in the stack
enable representative and redundant sampling.
Continuous sampling using the DioxinMonitoringSystem®
with monthly analysis of dioxins and dust by an accredited laboratory
is part to improve process control, to decrease dioxin emissions and to keep the flue gas treatment system under control.
