摘要

Ipsco Steel Inc., Montpelier Works, was interested in replacing the continuous opacity monitor (COM) installed on its EAF/LMF baghouse stack due to New Source Performance Standard (NSPS) requirements. The COM had been a high maintenance device due to high vibrations on the negative pressure baghouse stack. Further, the COM had a documented problem measuring the 3 percent opacity standard applied to the EAF emissions. Bag penetration by sparks in the negative pressure, pulse jet baghouse had been a continuing maintenance problem, and the COM had shown itself to be ineffective as a tool for identifying failed bag compartment locations. When opacity was identified in the stack, the COM provided the operator with no useful information as to emission source. When more than one compartment was involved, successive isolation of individual compartments provided no compartment identification information when using the COM as the emission indicator.To provide operators with a more proactive and useful tool, Ipsco investigated the feasibility of using a broken bag detection system. After a review of broken bag detection system technologies, a triboelectric base system was selected.
