Dioxins (polychlorinated dibenzodioxins, PCDDs) are among the most hazardous substances produced during waste incineration. Their emissions are regulated by law and must be monitored at all times. Current continuous sampling methods are time-consuming and provide only average values on dioxin leakage, depending on the time of integration. Real-time on-line measurements to determine dioxin concentration and the parameters of its formation are rare.
Background
Solution
Chlorinated hydrocarbons (CHCs) are the precursors to dioxin formation, and their measurement has been proven to be extremely important for optimizing combustion performance with respect to dioxide emission. Ion Molecule Reaction Mass Spectrometer (IMR-MS) - V&F's trademark technology - can measure CHCs down to ppb (billionths) ranges, instantly revealing immediate changes, and so facilitating timely intervention to control the combustion process.
Advantages
IMR-MS mass spectrometers from V&F provide the tools for real-time measurements of dioxin formation and related emissions from incinerators. The ability to measure on-line makes time-consuming sampling redundant. By measuring CHCs using V&F instruments, combustion conditions can be optimized, minimizing dioxin emissions.
