GMD Flue Gas Cooler, GMD TETST, a GMD Ten (10) Module Dust Collector System with a 500 HP Fan and 100' Free-Standing Stack. Exceeds requirements of Iron and Steel MACT.

GMD Environmental Technologies, Inc. has recently completed several GMD Cupola Emission Reduction and Treatment Systems (GMD CERTST) Projects. All are "dry" systems utilizing GMD Pulse Type Baghouses and GMD TETST for treating the lead laden baghouse dust. Some include GMD's Flue Gas Cooler to cool the off-gases before they enter the Fabric Filters. Designs are specific to the promulgated MACT Standards.

Replacing a Wet Scrubber, the system at Charlotte Pipe and Foundry Inc. uses GMD's Flue Gas Cooler to cool the off-gases, GMD's TETST to treat the baghouse lead laden dust and the GMD's Pulse Baghouses to filter the particulate from the off-gases.

Replacing wet scrubbing, the GMD CERTST at Waupaca Plant #1 is purported to be one-of-a-kind using "high" temperature dilution air cooling to lower the extremely high temperature of the Cupola combustor off-gase discharge to a temperature suitable for the inlet to the alloy tube GMD Flue Gas Cooler. As with all GMD CERTST, GMD's Totally Enclosed Treatment System (TETST) conditions the heavy metal (Pb) laden baghouse dust to a non-hazardous condition before it is discharged from the baghouse hopper(s) while at the same time treating the acid gas (SO₂) in the off-gasses before they exit to the atmosphere.
