Abstract

Systems for controlling an exhaust gas fan system. The control system may control one or more components of the exhaust system to optimize system performance and improve energy efficiency. The control system may be designed to maintain a substantially constant pressure in the exhaust header and provide a substantially constant flow through the exhaust fans. The control system is configured to control one or more of: modulation of one or more by-pass dampers; adjustment of the nozzle outlet area; varying the speed of the fans; the number and staging of fans.

IPC Classes  ?

• F23L 17/00 - Inducing draughtTops for chimneys or ventilating shaftsTerminals for flues
• B08B 15/00 - Preventing escape of dirt or fumes from the area where they are producedCollecting or removing dirt or fumes from that area
• F24F 11/72 - Control systems characterised by their outputsConstructional details thereof for controlling the supply of treated air, e.g. its pressure
• F24F 11/77 - Control systems characterised by their outputsConstructional details thereof for controlling the supply of treated air, e.g. its pressure for controlling air flow rate or air velocity by controlling the speed of ventilators
• F24F 13/10 - Air-flow control members, e.g. louvres, grilles, flaps or guide plates movable, e.g. dampers
• F24F 13/26 - Arrangements for air-circulation by means of induction, e.g. by fluid coupling or thermal effect
• F24F 110/40 - Pressure, e.g. wind pressure
• F24F 140/00 - Control inputs relating to system states

Abstract

Systems and methods for controlling an exhaust gas fan system. The control system may control one or more components of the exhaust system to optimize system performance and improve energy efficiency. The control system may be designed to maintain a substantially constant pressure in the exhaust header and provide a substantially constant flow through the exhaust fans. The control system may include software and hardware that allow the control system to control one or more of: modulation of one or more by-pass dampers; adjustment of the nozzle outlet area; varying the speed of the fans; the number and staging of fans. By utilizing and controlling one or more of these functions, the amount of energy being used may be minimized/optimized.
