In an integrated coal gasification combined cycle (IGCC) plant with carbon dioxide capture and storage (CCS), hydrogen-rich fuels with a wide range of hydrogen contents are supplied to a gas turbine. As an advanced burner operating with such fuels, a multi-hole co-axial jet burner is being developed to achieve dry low-NOx combustion. This paper suggests two effective perforated plate's configurations for suppressing the combustion noise, which prevents low-NOx operation. The one has a convex surface with uniform air hole diameters, and the other has a convex surface with radial air-hole-diameter distribution. This paper experimentally investigates the effectiveness by atmospheric experiments. The results are summarized as follows: (1) The convex perforated plate expands the stable low-NOx operating range without the combustion noise and reduces NOx emissions. (2) The convex perforated plate with radial air-hole-diameter distribution further expands the stable low-NOx operating range.
