Abstract PERFORMANCE EVALUATION OF BURNER AND THE REACTOR TUBE OF FLAME FOR A SPRAY PYROLYSIS PROCESS. Flame spray pyrolysis is a versatile process in the syntheses of various functional materials. This work reports the performance of a diffusion flame built from a coaxial burner and a Pyrex-glass tube reactor with respect to the relatively low propane flow rates (0.1-0.8 L/min). The burner comprised of three cylindrically tubes with three inlets for fuel (propane), oxidant (oxygen) and precursor aerosol. Three flame parameters were measured, i.e. the flame height, flame temperature and reactor temperature profile, respectively. The test results showed the increase of the flame height and temperature with increasing of propane flow rate. The temperature profile measurements showed the decreasing as the height above burner increased; and temperature profile increased at the increasing propane flow rate. The reactor temperature was in the range of 36-190°C at low propane flow rates of 0.1-0.8 L/min. In conclusion, control of flame process parameters could be conducted by controlling of propane flow rate.

The burner comprised of three cylindrically tubes with three inlets for fuel (propane), oxidant (oxygen) and precursor aerosol.
Three flame parameters were measured, i.
