Specially designed for various glass production lines such as float glass, photovoltaic glass, and specialty glass, this induced draft fan is the core power equipment for the exhaust gas treatment and waste heat recovery systems of critical sections like the melting furnace, tin bath, lehr, and raw material processing. The fan is primarily used to stably extract dust-laden, corrosive gases (e.g., SO₂, NOₓ, HCl, alkali metal vapors) and hot air from these high-temperature processes, conveying them to waste heat boilers, desulfurization/denitrification (SCR/SNCR) units, or bag filters. This ensures environmental compliance, efficient energy utilization, and process stability for the production line. It operates under complex conditions, requiring long-term resistance to high temperatures (300°C~500°C), corrosion, dust, and the severe challenges of hot starts and stops.
