The effect of the degrees of atomization on gaseous emissions, flame stability and combustion efficiency has been investigated. Rich, heterogeneous mixtures of kerosine and air were injected into the combustion air using an acoustic atomizer and flames were stabilized by means of a swirler. Experiments were made to inlet air temperatures of 450, 550 and 650K under atmospheric pressure. The overall equivalence ratio ranged from the blow-off limit to unity. The degrees of atomization were varied by changing the feeding rate of the atomizing air. In this report the emission indices of NOx have been compared with those for some simplified model combustors burning homogeneous mixtures and for fuel-rich primary zone combustors burning sprays from conventional pressure atomizers or premixed sprays from a mixing tubes. The emission index of NOx at the exit is correlated with the adiabatic flame temperature Tf by EI(NOx)∝ exp(0.002Tf) the temperature coefficient being compared with a typical value of 0.006 for homogenous mixtures. Standard Arrhenius plots of the rate of EI(NOx)versus 1/Tf give a typical value of 18 kcal/mol for the activation energy. NOx emission decreases with increasing degrees of atomization and mixing, the effect being more significant at higher inlet air temperatures. The emission indices of CO, THC and NOx at 650K are 8, 0.03 and 1.3, respectively, under the highest degree of atomization with a combustion efficiency greater than 99.9％ and a blow-off velocity of about 60m/sec. |
