Power fans are large-scale centrifugal or axial units used in utility and industrial power plants to provide forced-draft air for boilers, induced-draft exhaust, and general equipment ventilation.
Forced-draft (FD) fans deliver 100,000–500,000 CFM at moderate pressures to preheat feedwater heaters and support combustion. Induced-draft (ID) fans handle flue gases, moving exhaust through air-preheaters and electrostatic precipitators at temperatures up to 350 °C.
They feature robust impeller designs, high-efficiency motors, and explosion-proof options. Variable frequency drives (VFDs) enable load-following control, matching airflow to generation output to optimize efficiency and reduce emissions.
Split-casing construction, external lubrication, and integrated vibration sensors ensure reliable, continuous operation within demanding power-generation environments.
