Filter diagnostics for reducing opacity

With emissions from facilities being reduced it is important to maintain the efficiency of your baghouse. This is normally viewed to mean extra man-hours and additional costs. However this is not necessarily true. Most bag filters do not get looked at unless they limit production or emissions are high. Outside of either situation they are not considered a critical part of the overall production process. This usually means that the less money spent the better. This is especially true when it comes to bag filter monitoring and control. This paper will present information from two (2) installations, a pulse-jet baghouse and a reverse air baghouse, where the owners invested in upgrading their bag filter monitoring and/or controls. The investments not only reduced emissions and increased product capture & efficiencies, but also reduced operational and maintenance costs as well.
