| Summary: | NOx and PM are the major product results from the combustion of diesel either in
internal combustion engine or external burner system. Thus, the emulsification concept from diesel
and water were studied with focusing in controlling of combustion process in order to minimize the
harmful emission. The main purpose of this research is to investigate the effects of diesel-water
emulsification on mixture formation, burning process and flame development in burner system. The
studed parameters include equivalent ratio, water content in diesel-water emulsification and spray
characteristics such as spray penetration length, spray angle and spray area. The spray image of
different diesel-water ratio and equivalence ratio can be investigated by direct photography method
with a digital camera. The real spray images with the time changes was analyzed and compared with
based diesel fuel. The results show that the higher of water contents due to higher viscosity
influences the higher penetration length and lower spray angle thus predominantly the lower
combustible mixture and lower the flame penetration. |
