Combustion air systems for cross-fired furnaces

Central operation - Equipment
  • Common and reserve ventilators for all ports
  • Switch cabinets for inverter operating ventilator drive motor
  • Electrically- or pneumatically-controlled throttle valve with automatic transfer to the reserve ventilator with immediate messaging to the process control system
  • Ducting system to each burner port
  • Airflow sensing by means of venturi ducting or measuring orifices in the discharge side ducting to the individual ports
Individual operation - Equipment
  • An independently operating fan is attached to each port. The ventilator’s discharge side ducting are linked to the reversal system of the attached ports
  • Switch cabinets for inverter operating ventilator drive motor
  • Airflow sensing by means of suction-side, inflow measuring nozzle on each ventilator.
