Negative Pressure Operation: Unlike Forced Draft (FD) fans that push air in, ID fans suck gases out, ensuring the furnace operates under negative pressure to prevent leakage of hazardous gases. Components and Design: Typically centrifugal in design, these fans often feature hardened materials or wear padding on blades to withstand erosion from fly ash and harsh, high-temperature exhaust gases. Location: Installed between the dust collector/precipitator (ESP) and the stack/chimney. Applications: Commonly used in power plants, cement plants, steel production, and food processing industries to remove exhaust, smoke, and odors.

Function: Removes flue gases, maintains negative pressure, and ensures proper air flow, enhancing combustion efficiency.Location: Installed between the pollution control equipment (e.g., electrostatic precipitator, dust collector) and the chimney.Working Principle: Centrifugal force is used to suck hot gases out of the furnace, creating a draft lower than atmospheric pressure.Design & Features: Designed to handle high-temperature gases (often up to \(450{\circ }C\)) and particulate matter. They often feature robust impellers with wear padding for abrasive dust.Applications: Power plants, cement plants, steel mills, and food processing for ventilation and combustion control.
