FAQ

What types of pollutants can the Combustion Flue Gas Treatment System remove?

The system removes solid particles, oil smoke, VOCs, inorganic gases, H₂S, NH₃, thiols, and other odors. It uses multi-stage filtration, UV photolysis, and activated carbon adsorption to ensure flue gases meet environmental standards before discharge.

How does the heat exchange system lower the temperature of exhaust gas?

The heat exchange system uses circulating water through a heat exchanger placed in the exhaust duct. High-temperature gas transfers its heat to the water, effectively reducing the gas temperature and protecting downstream components and filters.

What maintenance is required for the high-efficiency filter unit?

High-efficiency HEPA filters should be inspected regularly for dust accumulation. Replace them when efficiency drops, typically every 12–18 months depending on usage. Careful cleaning may prolong service life, but avoid washing glass fiber materials as it can damage filtration performance.

Can the exhaust fan output be adjusted?

Yes, the exhaust fan is controlled via a frequency inverter, allowing precise adjustment of smoke extraction volume to match the gas flow from combustion experiments, ensuring optimal purification and energy efficiency.

What standards does the system comply with?

It meets GB 16297-1996 (China Comprehensive Emission Standard of Air Pollutants), ISO 14001. EN 1822 (HEPA), and ASHRAE 52.2 for air filter performance.
