• Rotameters are employed to measure the flow rate of fuel and air supplied to the burner.


• The supply air and fuel (CNG) 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.


• While mounting the rotameters, ensure their alignment with the help of sprit level.

• Open the air inlet valve.


• Set the desired pressure in the inlet pressure regulator.


• Fix CNG fuel flow rate.


• Now open the needle valve and set the desired air flow with the help of rotameter to obtain the specified equivalence ratio.


• Now ignite the mixture at the burner exit.


• Wait for sometime till no further changes in the flame shape is observed.
