| Abstract: | The characteristics of gasification,pyrolysis and combustion of LP1846 sin-gle droplet whose initial diameter is from 1.8 to 2.4 mm have been investigated in alco-hol flame of 950 C.The photographes of time series of droplet from getting into flameto combustion end are given.Ignition delay time and lifetime of droplet,and the varia-tions of droplet diameter as a function of time are measured quantitatively.The meanloss rate of droplet surface area is also calculated. |
