Emission characteristics of premix and prevaporization combustor

摘要

In order to clarify the relationship between fuel spray characteristics and combustion character- istics, combustion tests of the premix and prevaporization combustor were carried out. The lower flammability limit becomes leaner for a longer vaporization pipe and combustion air with a higher temperature and larger velocity. On decreasing the total equivalence ratio, the carbon monoxide concentration first decreases and then increases beyond the equivalence ratio of 0.6.
