Experimental Setup For Premixed Flame

Posted by Prof D P Mishra

  • The burner has to be kept in an enclosed chamber to avoid the entrainment of ambient air.
  • The burner has two inlets; one for the fuel-air mixture and the other one for nitrogen gas, which will act as a curtain to the flame.
  • Rotameters are employed to measure the flow rate of fuel and air supplied to the burner.
  • The supply air and fuel are controlled through a fine control needle valve, fitted just before the rotameters.
  • Care should be taken to calibrate the measuring equipments before using in the experimental setup.
  • Screens are provided before the burner exit to remove the eddies from the inlet flow.
  • Camera has to be kept sufficient distance from the flame.
  • While mounting the rotameters, ensure their alignment with the help of sprit level.
