The most effective technology currently available for controlling NO_x emissions from heavy-duty industrial gas turbines consists of diluent injection in the combustor reaction zone coupled with selective catalytic reduction (SCR) De-NO_x in the gas turbine exhaust. A competing technology with the potential for achieving comparable emissions levels at substantially lower capital investment and operating cost is catalytic combustion of lean premixed fuel and air within the gas turbine. Under Tokyo Electric Power Company (TEPCO) sponsorship, a preliminary design of a catalytic combustion system using natural gas fuel has been prepared for the GE Model MS9001E gas turbine. One of the key elements of the catalytic combustor is the fuel/air preparation system, which must provide fluid conditions of uniform temperature, velocity, and mixture strength at the catalytic reactor inlet. A multiple venturi tube (MVT) fuel injector has experimentally demonstrated the capability of meeting catalytic combustor requirements during atmospheric pressure testing at the GE gas turbine combustion test facility under the sponsorship of the Southern California Edison Company (SCE).
