Abstract

A hydrogen combustor for applying to 5MWe-class small gas turbines was designed and experimentally investigated in this study. A swirl type, not a multi-tube type, which is widely used in the recently developed hydrogen combustor, was applied to this hydrogen combustor. The test was conducted at the inlet temperature of 410°C which is derived from cycle analysis and at atmospheric pressure (1.35 barA). First, the ignition test was performed while switching from NG flame to hydrogen flame. Flame structures (from direct photo and OH* chemiluminescence), NOX emission and dynamic pressure were observed with varying adiabatic flame temperatures and fuel splits of FC1 and FC2. Lean blowout and flashback characteristics were investigated with varying equivalence ratio and flow velocity. Flame was converted from V-shaped flame to M-shaped flame as equivalence ratio increases and M-shaped one has higher NOX emissions. NOX emission is under 3 ppm (@15% O2) at 1860 K of flame temperature which is equivalent or even lower level of NG combustors. It was found that the operating range from lean blowout to flashback is very wide.
