In this study, we burn the bamboo powder packed layer placed on stainless steel mesh to know how the clinker is made. We carried out the mass change of the mesh after burning, mesh surface observation and also measured the adsorption amount and size of bottom ash. In the process of bottom ash formation, two stages were confirmed. Firstly, as the emission of volatiles from bamboo pyrolysis and their combustion at about 1000 K or less occurred, the metal oxides with low melting point andfine white particles of about 10 μm are adsorbed on the stainless steel mesh. Secondly, as char combustion at about 1000 K occurred, there could be two cases of clinker generate. For case one, the small particles with low and high melting points deposit repeatedly and change to clinker in a large massive state. For the other case, lump is adsorbed by the high melting point oxide and small particles due to the low melting point oxide adhere so as to cover the giant lump and become huge.
