Abstract
The purpose of this study was to improve the combustion state by excess enthalpy combustion because the combustion state was unstable under low fuel flow conditions. In this experiment, the excess enthalpy combustion performed stacked grates in longitudinal and transverse. Temperatures in the combustor and concentrations of exhaust gas were measured at same positions last year. As the result, temperatures in the combustor were increased as a whole with longitudinal stacked grate. In addition, temperatures in the primary combustion chamber and enthalpy at the exit were increased which condition with low fuel flow rate using longitudinal stacked grate. Thus, it was found that gasification-reaction was promoted further and the enthalpy increased using the longitudinal stacked grate.
