The simultaneous removal of particulate matter (PM) and nitrogen oxides (NOx) in biomass and waste incineration facilities remains challenging due to space limitations, variable operating conditions, and the complexity of multi-unit emission control systems. In previous pilot-scale tests, pleated filter bags incorporating SCR pellet catalyst cartridges demonstrated the technical feasibility of integrated PM filtration and NOx reduction, showing stable filtration behavior and effective DeNOx performance under controlled conditions. Building on these pilot-scale results, the present study advances the technology to an industrial-scale field demonstration under real plant operation.

Following pilot validation, pleated SCR pellet catalyst filter bags were installed in a wood waste incineration boiler and operated as part of the plant’s routine emission control system. The demonstration aimed to verify long-term operational stability, scalability, and reliability under fluctuating flue gas temperature, dust loading, and boiler load conditions typical of industrial biomass incineration. Key performance indicators included PM removal efficiency, NOx conversion efficiency, pressure drop evolution, and ammonia injection behavior.

The industrial-scale operation confirmed that the pleated configuration ensured stable dust cake formation and controlled pressure drop during extended continuous operation. Simultaneously, the integrated SCR pellet catalyst cartridges maintained consistent NOx reduction performance without adversely affecting filtration characteristics or inducing abnormal pressure increase. No mechanical damage or catalyst-related operational issues were observed during the field demonstration period.

The results demonstrate a clear ...
