Emission control & air dedusting for fuel oil boilers - Oil, Gas & Refineries - Oil

For PM emission control in high temperature exhaust streams, such as fuel oil boilers, usual dedusters such as bag filters are very maintenance demanding. Particularly, diesel and fuel particulates are very sticky and clog to filter elements, unless protection reagents are used. Flue gas cooling is also needed in front of the filter when temperatures are higher than 200 ºC. On the other hand, regular cyclones and multicyclones are frequently not able to reduce emissions to present emission limits.
