Abstract To better understand cenosphere formation and differences between two types of cenosphere morphologies in HFO combustion. Falling droplet combustion inside a preheated furnace was done under a series of conditions and particulate matters are collected from the cooled exhaust gas. By using SEM, morphology of cenosphere samples can be characterized. Results show that air co-flow rate and entrance zone temperature inside furnace are the two main factors that affect the morphology of cenospheres. The morphology changes from porous shell to skeleton-membrane if air co-flow rate decreases from 150 lpm to 30 lpm or if entrance zone temperature decreases from 600 C to 250 C. Relatively high entrance zone temperature and high air co-flow rate are both required to generate cenospheres with porous shell structure.
