Heightened Focus on Particulate-Matter Health Impacts

PM2.5 exposure studies indicate GDP losses of 1-4% in Asia; governments now treat air pollution as an economic issue, not merely an environmental one^{(5)Clean Air Asia, “New Report Finds Decarbonization of Asia Will Bring Co-Benefits to Clean Air,” cleanairasia.org} . The cement sector’s shift to bag-type dust collectors exemplifies health-driven purchasing criteria, as pulse-jet designs capture more than 99% of particles and comfortably meet ambient standards. Material science breakthroughs, such as corn-protein nano filters that trap 99.5% fine particles, broaden the arsenal available to designers. These advances feed into premium upgrade cycles even where legal limits remain unchanged.

Carbon-Capture-Ready AQCS Retrofits

Utilities and industrial boilers plan for 10- to 20-year asset lives. Adding absorber columns, duct realignment, and lower-temperature catalyst beds at the retrofit stage lowers the future cost of attaching amine or calcium looping units. U.S. plants installing mercury-control equipment spent at least USD 6.1 billion during 2015-2016, a cost now benchmarked for decision-makers evaluating capture-ready options^{(6)U.S. Energy Information Administration, “EIA Electricity Generator Data Show Power Industry Response to EPA Mercury Limits,” eia.gov} . AI-enabled process optimization promises 15% waste reduction and 30% product quality gains, improving the business case for advanced retrofits.

High Capex & O&M Costs

Ultra-low-emission systems demand specialized alloys, high-surface-area catalysts, and sophisticated controls. U.S. coal plants spent USD 6.1 billion in 15 months to meet mercury standards, with activated-carbon injection favored for quicker deployment. Smaller operators often postpone upgrades or opt for modular packages with staged implementation. Vendors counter cost barriers by offering build-own-operate models and digital twins that extend service revenues.

Shift Toward Renewable Energy Curbing New Installations

As utility-scale solar and wind displace coal in tender pipelines, greenfield prospects for large-volume flue-gas systems shrink. Yet this trend drives retrofit, biomass co-firing, and waste-to-energy conversions. Babcock & Wilcox’s Michigan coal-to-biomass project couples emissions control with CO₂ capture to produce net-negative power, signalling how legacy fleets remain addressable.

Segment Analysis

By Type: FGD Dominance Amid Filter Innovation

Flue-gas desulfurization retained a 40.1% stake in the industrial air quality control systems market share in 2024, anchored by its indispensability in the combustion of sulfur-rich coal and petcoke. Fabric/ceramic filters outpaced all rivals, achieving an 8.9% CAGR, driven by the need for simultaneous removal of PM, SOx, and NOx. Electrostatic precipitators remain workhorses in bulk power units, while scrubbers gain favor in marine retrofits and chemical plants. Selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) sustain demand where NOx caps tighten.

FGD growth stays steady as China and India retrofit limestone-gypsum units to ultra-low emission standards, often integrating oxidation air blowers and gypsum dewatering upgrades. Fabric filters excel in cement and steel lines, where high-temperature catalytic filter candles achieve <5 mg/Nm³ PM emissions, along with 90% NOx reduction at 350 °F. The industrial air quality control systems market size for fabric filters is estimated to climb from USD 15.6 billion in 2025 to USD 25.0 billion by 2030. Adoption quickens when plant owners replace aging ESPs with baghouses during scheduled outages, leveraging existing ducts and fans to minimize downtime.
