Recently, micro-combustors which combust hydrocarbon fuels at micro scale are expected to be applied for heating, generating electronic power, and so on. In general, it is difficult to combust premixed gas in a narrow space. The combustor size becomes smaller, the ratio of heat loss to heat input becomes larger, and combustion becomes more unstable. However, micro-combustors use burnt gas enthalpy to stabilize combustion. This research used quartz glass tube with relatively small inner diameter as a combustor. External heating of the tube was made by a Bunsen burner or by covering it with another quartz glass tube with or without steel wool in which the burnt gas flew. We investigated flame stabilization condition and flame velocity inside the narrow tube.
