Performance Evaluation of a Pilot-scale Pulse-jet Baghouse for Operation with Airpol’s Gas Suspension Absorption Process at Tva’s Center for Emissions Research

Executive Summary Performance evaluation of a pulse-jet baghouse operating with AirPol's Gas Suspension Absorption (GSA) process was conducted at TVA's Center for Emissions Research (CER) facility. The baghouse filtered approximately 5000 acfm of flue gas and was operated in two different configurations: in parallel with the electrostatic precipitator (ESP) at an air-to-cloth of 4.0 acfm/ft2 and in series with the ESP at an air-to-cloth of 12.0 acfm/ft2. The operation of the baghouse with the GSA process was very successful in both modes of operation. SO2 removal was 3 to 5% higher for the baghouse operating in parallel with the ESP than with the ESP alone. For the baghouse operating in series with the ESP, the SO2 removal was 0 to 2% higher than the ESP alone. The outlet emissions rate through the baghouse was very low for both configurations. Other baghouse performance parameters (tubesheet pressure drop, pulsing frequency, and collection efficiency) were within the preferred range of operation for pulse-jet baghouses.
