Industry Overview
The global power plant boiler flue gas treatment industry is undergoing profound changes. Driven by the dual goals of carbon neutrality and increasingly stringent environmental regulations in various countries, the market is moving from the end of pipe treatment of a single pollutant to a comprehensive development stage of multi pollutant collaborative control, resource utilization, and low-carbon integration.
Global energy efficiency and emissions standards continue to tighten, accelerating the phasing out of outdated production capacity and increasing industry concentration. Policy and market mechanisms.
The industry is accelerating its transition toward synergistic pollution and carbon reduction. Traditional desulfurization, denitrification, and dust removal technologies are being upgraded to enhance their ability to capture fine particulate matter such as PM2.5; breakthroughs have been achieved in coupling flue gas treatment with CCUS technologies, enabling the removal of multiple pollutants and their resource recovery.
AI and digital twin technologies enable intelligent flue gas treatment, dynamically optimize parameters, ensure stable compliance with standards across a wide load range, and reduce energy consumption and O&M costs.

Difficulties in flue gas treatment of power plant boilers
The boiler load fluctuates significantly between 20% and 100%, and the flue gas temperature and flow rate are unstable. Traditional denitrification processes are difficult to adapt to changes in operating conditions, and are prone to insufficient catalyst activity and repeated emissions exceeding standards.
Simultaneously remove SO ₂ NOx、 Dust and fine particulate matter, traditional step-by-step treatment has low efficiency and is prone to equipment blockage, corrosion, and high operating costs
The site is narrow, making it difficult to upgrade denitrification/desulfurization equipment, and coal co firing (biomass/sludge) leads to complex flue gas composition, making catalysts prone to poisoning and deactivation.
Process Route and Technical Description
This process route can stably achieve ultra-low emissions of particulate matter, SO₂ and NOₓ. The core procedures are outlined below
02
Joint denitrification stage (SNCR+SCR)
Inject ammonia/urea into the furnace at 850-1100 ℃, and use SNCR to preliminarily remove 30% -50% NOx; Further SCR deep denitrification results in a total efficiency of ≥ 80%, reducing ammonia escape and catalyst costs.
02
High efficiency dust removal stage (FF)
The bag filter physically intercepts particulate matter, with a dust removal efficiency of ≥ 99.9%, providing clean flue gas for subsequent processes.
02
Wet flue gas desulfurization stage (FGD)
The absorption tower reacts with limestone/magnesium oxide slurry to remove SO ₂ with an efficiency of ≥ 95%, and the by-products can be utilized as resources.
02
Deep Purification Stage (WESP)
After desulfurization, further capture fine particles, gypsum droplets, etc., eliminate "gypsum rain" and "white smoke", and ensure that the exhaust particulate matter is less than 5mg/m ³.
