Basic Study on Combustion Characteristics of Coaxial Premixed Burner with the Addition of $Al_2O_3$ Particles

摘要: Thermal spray technology has been used in many industrial application. Especially, thermal coating have employed with the purposes of achieving better resistances abrasion, heat and corrosion. In previous studies on coating, characteristics from perspective combustion engineering not investigated sufficiently, while material coated substrates widely. this study, effect particles flame behavior was experimentally investigated. The amount injected measured using light scattering method temperature estimated a two-color method. Various flame-spray interactions were observed it found that high zone near is elongated by density. Based these results, applicability discussed.
