Glass

What the fans do here

Glass furnaces need combustion air at steady pressure, cooling air on the furnace structure, and high pressure blowers for forming and annealing. Fume exhaust from the regenerators is hot and carries batch dust, and goes to a bag filter with a dilution air blower ahead of it.

Applications in this industry

Application	What it does	Type usually selected
Combustion Air Blower	Feeds a burner with air at the pressure the burner register needs. Sized for the burner turndown range, and often fitted with an inlet silencer.	Backward curved and radial tipped
High Pressure Blower	Delivers combustion, aeration and conveying air where the system resistance runs to several thousand millimetres of water column in a single stage.	Backward curved and radial tipped
Hot Air Fan	Circulates or supplies air at elevated temperature to a dryer, oven or kiln. Selected at the hot density with the shaft and bearing arrangement built for continuous hot running.	Backward curved and backward inclined
Dilution Air Blower	Injects ambient air into a hot flue gas stream to bring it down to a temperature the downstream bag filter or fan can accept.	Backward curved
Fume Exhaust System	Hoods, ducting and an exhaust fan that capture fume at source and deliver it to a scrubber, bag filter or stack. Fan material follows the fume: stainless steel, PP-FRP or rubber lined where it is corrosive.	Backward inclined and radial tipped
