A Dog House Hood is a highly efficient industrial fume extraction enclosure designed to capture smoke, fumes, dust, and hot gases directly from the source by partially or fully enclosing the emission-generating process.
Unlike canopy hoods that rely primarily on the natural upward movement of hot gases, a dog house hood provides a controlled enclosure around the process area, significantly improving contaminant capture efficiency and reducing fugitive emissions.
Dog House Hoods are widely used in induction furnaces, electric arc furnaces, foundries, steel plants, non-ferrous metal melting units, alloy production facilities, and various high-temperature industrial applications. By enclosing the emission zone, the hood prevents the escape of smoke and fumes into the workplace, resulting in superior air quality, enhanced worker safety, and improved environmental compliance.
The Dog House Hood operates on the principle of enclosure and induced draft. The hood structure surrounds the furnace or process area, creating a confined space where smoke, fumes, and particulate matter are generated.
A centrifugal blower connected to the extraction system maintains negative pressure within the enclosure, ensuring that contaminants are continuously drawn into the ducting system before they can escape into the surrounding environment.
The collected pollutants are transported through ducting to a dust collector, bag filter, wet scrubber, or other air pollution control equipment where contaminants are removed before clean air is discharged into the atmosphere.
Dog House Fume Extraction Systems are designed for induction furnace operations with partial or full enclosure options. They deliver high fume and dust capture efficiency, effectively controlling fugitive emissions during charging, melting, and pouring processes.
