Structure of Solid-Gas Hybrid Flames Yata H, Tomita E, Matsugi D, Yamazaki T and Nakamura Y

Abstract

Herein, the flame structure of a “hybrid fuel” as a mixture of combustible gas and solids in powder form was studied experimentally. A circular burner was used, and a rich premixed flame was achieved. The results showed that the powder underwent high-temperature pyrolysis in the region sandwiched by the inner and outer flames to gasify quickly. The gasification efficiency was estimated experimentally to prove that a sufficient amount of powder could be burned out in this system.
