Industrial Ventilation and Exhaust

Industrial ventilation and exhaust systems, followed through a fourth-year apprentice in a Cleveland sheet metal contractor: dilution and local exhaust principles, commercial kitchen hoods, grease ducts and their clearances and rated enclosures, make-up air and kitchen balance, hood fire suppression and cleaning, local exhaust hood design, dust collectors, combustible dust hazards and explosion protection, welding, spray and laboratory fume exhaust, industrial fans and spark-resistant construction, codes, permits and inspections, and a capstone closing out a restaurant kitchen exhaust package and a woodshop dust collection system.

What you'll learn

  • Explain the purposes of industrial ventilation, distinguish general dilution from local exhaust, and calculate dilution airflow for a contaminant release
  • Describe commercial kitchen hood types, listed and unlisted hood airflows, filters and the appliance duty classes that drive exhaust rates
  • Build and check field-built grease ducts for material, welds, slope, cleanouts, clearances and fire-rated enclosures in line with NFPA 96 as adopted
  • Balance kitchen exhaust against make-up air and transfer air, temper make-up air, and set the interlocks between fans, heaters and suppression
  • Coordinate with wet-chemical suppression systems and explain the inspection, cleaning and record requirements for hoods, ducts and fans
  • Design and check local exhaust hoods using capture velocity, hood airflow equations, entry losses and transport velocity
  • Select and size dust collectors, including fabric filters by air-to-cloth ratio and cyclones by cut size, and plan their discharge and installation
  • Recognize combustible dust hazards and the protection methods of venting, isolation, suppression, bonding and housekeeping
  • Describe exhaust for welding fume, spray finishing, laboratory fume hoods, corrosive processes and hospital isolation rooms, with suitable materials and stacks
  • Choose fan types for industrial service, apply the fan laws and power equations, avoid system effect and specify spark-resistant construction
  • Identify the codes, standards, permits and inspections that apply to kitchen, dust and fume exhaust as adopted in the local jurisdiction and coordinate the trades involved
  • Assemble a closeout review package that verifies design figures, test records, interlocks and owner maintenance for industrial ventilation systems
