Emission Control Materials for Waste Incineration
Emission problems, pollutants, operating conditions and recommended materials for the waste incineration sector.
Typical emission problems
- CO peaks from incomplete combustion
- Temperature fluctuation
- Complex composition including acid gases
- Dioxin precursors requiring polishing stages
Main pollutants
- CO
- VOCs
- SO₂
- NOx
- Dust
- Acid gases
Operating conditions
Incinerator exhaust temperature and CO load fluctuate. Catalysts must tolerate thermal cycling and multi-pollutant conditions.
Recommended material selection
- CO oxidation catalyst for CO control
- SCR catalyst where NOx removal is required
- Activated carbon injection or fixed-bed polishing for dioxin control
Engineering considerations
Waste incineration flue gas is the most aggressive stream in emission control: HCl, SO₂, heavy metals, dioxin precursors, dynamic CO spikes and moisture in one gas. Catalysts and adsorbents are placed downstream of the dedicated gas-cleaning stages — acid scrubbers, bag filters and reagent injection — never in the raw gas.
CO is both a pollutant and a combustion-quality signal; plants use CO oxidation catalyst as a polishing stage and monitor CO spikes as evidence of incomplete burnout. Dioxin control is typically handled by activated carbon injection or fixed-bed polishing upstream of the stack.
Every material in this service needs a defined replacement cycle: carbon saturates in months, catalyst faces chloride and metal exposure, and bag filters carry the particulate load. Lifecycle budgeting is part of the design.
