This paper presents a simplified analysis to determine the variables that affect the empirical correlation factor used in the lead peroxide method. The rate of sulfation has been determined from two different models. In the first model, the mass transfer rate is calculated from the gas phase resistance alone whereas in the second model, the diffusion resistance in the gel phase is assumed to be the rate limiting step. Although the gas phase and the gel phase resistances may be both important in the actual case, it has been found that the correlation factor based on the first model is adequate to describe general experimental observations. Reasonable agreement has been obtained between the measured and the calculated va|ue of the correlation factor. 相似文献

The effect of ammonia in the fuel on NOx emissions was investigated through laboratory experiments and field burner tests. It was found that the degree of conversion of pm-monia to NOx was a strong function of excess air, ammonia content in the fuel, and of the degree of mixing in the flame. In premixed laboratory flames concentrations of NOx above the peak equilibrium amounts were produced. In furnace diffusion flames the conversion to NOx was much less. At substoichiometric air-fuel ratios all the ammonia appears to pyrolize, forming N2, and only very little NOx. Several methods for burning ammonia to produce low NOx emissions were investigated. 相似文献
