IMPROVE EFFICIENCY, OPERATION AND CONSUMPTION WITH THE GOAL OF REDUCING OPERATION & MAINTENANCE SPENDING

DELTA WING DSI (DRY SORBENT INJECTION)

Delta Wing® DSI is a lower capital cost system that can be used to remove acid gas constituents including SO2, SO3, HCI and mercury. Although not a solution for every plant, Delta Wing® DSI provides a useful means to improve opacity and reduce acid gas emissions enough to comply with MATS emission levels.

DSI systems are comprised of three basic components; material handling equipment to unload and store sorbent (lime, trona, sodium bicarbonate or PAC); pneumatic conveying systems to transport the sorbents from storage to ductwork inspection points and duct work injection to introduce the sorbent into the flue gas stream. Delta Wing® DSI provides the essential benefit of proactively mixing the sorbent with the flue gas to improve system efficiency and sorbent utilization.

CIRCULATING DRY FLUID BED SCRUBBER (CDS)

This is a cost-effective, highly efficient system designed to remove acid gas constituents. The Turbosorp® Circulating Dry Fluid Bed Scrubber is a cost effective, highly efficient system designed to remove acid gas constituents, including SO2, SO3, HCl, HF, mercury, and other trace pollutants from flue gas streams. Turbosorp® is ideally suited for coals with sulfur contents greater than 3.0%, and typically results in acid gas removal efficiencies greater than 97%.

SELECTIVE CATALYTIC REDUCTION (SCR)

We design SCRs to be fully integrated with the boiler to ensure seamless operations. Our complete integrated SCR systems are comprised of Computational Fluid Dynamics (CFD) and physical modeling, ductwork, reactors, support steel, initial catalyst charge, fans, complete reagent loading, storage, injection systems, startup, testing, and training.

SCR Design Features include:

  • Two four layer reactors per unit
  • Three initially installed layer and one future layer of catalyst
  • Inlet and outlet NOx analyzers
  • SCR inlet temperature control (per reactor)
  • Two double louver economizer bypass dampers
  • One single louver backpressure damper
  • Delta Wing™ static mixers with six ammonia injectors
  • Six sonic horns per installed catalyst layer
WET FLUE GAS DESULPHURIZATION (SINGLE FGD)

We provide flue gas desulfurization systems to the power generation industry where applications require high efficieny SO2 removal while still effectively managing power consumption.
