Key technologies for ultra-low emissions from coal-fired power …
A typical coal-fired power plant with conventional emissions control technologies is illustrated in Fig. 3.1. These techniques include low-NO x burners (LNBs) and selective catalytic reduction (SCR) for NO x control, electrostatic precipitator (ESP), or fabric filter (FF) for PM control, and flue gas desulfurization (FGD) for SO2 control.Web

The pre-coating of a fabric filter is a preventive measure to protect the filter media from moisture and other upset conditions that may occur within the start-up of a coal fired boiler. The use of No. 2 Fuel Oil adds an additional area of caution, especially when utilizing any of the ePTFE membrane media in the baghouse.Web
