B&W MEGTEC - Pulse Jet Fabric Filters
Pulse jet fabric filters (baghouses) for costeffective particulate emissions control. B&W MEGTEC provides cost-effective control of particulate emissions with our proven pulse jet fabric filter technology. B&W provides a strong history of industrial fabric filters dating from the 1930s. Through our innovative technologies, we have provided some of the lowest emission fabric filters in the world for a variety of industries including steel, cement, incineration and steam generating boilers that utilize a variety of fossil and biomass-based fuels.
Our continuing R&D has led to several innovations that have reduced the cost of particulate control solutions. Long bag technology has been in commercial operation for more than ten years, with bags often reaching a length of ten meters. In applications where an existing ESP can no longer meet plant emissions requirements, long bag technology has enabled successful conversion of an existing dry ESP to a pulse jet fabric filter.
Fabric filters for multi-pollutant control
Our focus on providing systems solutions for multipollutant control has led to such innovative designs as locating a clean-side SCR for nitrogen oxides (NOX) control after a spray dryer absorber and fabric filter for sulfur dioxide (SO2) and particulate control. This strategy includes both the traditional collection of ash or particulates, as well as hazardous air pollutants (HAPs).
Integrating fabric filters with our sorbent injection and flue gas desulfurization (FGD) technologies also provides low HAP emissions in a variety of applications. Examples of sorbents used with fabric filters include powdered activated carbon for mercury control and trona or lime for control of SO2. Trona or lime may also be the economic choice for SO2 control
on certain applications.
