概要 （英文）

A 1500 -CLASS GAS TURBINE COMBUSTOR FOR IGCCSYSTEMS WAS DESIGNED TO INCREASE THE THERMAL EFFICIENCY OF POWER GENERATION SYSTEMS. TO REDUCE NOX EMISSION,THIS COMBUSTOR WAS IMPROVED BY WEAKENING THE MIXING FLOW OF THE SECONDARY AIR. THE COMBUSTOR WAS TESTED AND EVALUATED OF ATMOSPHERIC PRESSURE. THE RESULTS ARE AS FOLLOWS: (1)THE AMMONIA CONVERSION TO NOX WAS 34% UNDER FULL-LOAD CONDITIONS (AMMONIA CONCENTRATION 1000 PPM, METHANE CONCENTRATION 1.0%) WHICH IS A DECREASE FROM THE PREVIOUS COMBUSTOR. THE REACTION FROM THE AMMONIA INTERMEDIATE TO NOX IN THE SECONDARY COMBUSTION REGION IS SUPPRESSED BY THE WEAKED MIXING FLOW OF THE SECONDARY AIR. (2)CO EMISSION WAS ABOUT 2000 PPM (CONBUSTION EFFICIENCY 98.7%) UNDER FULL-LOAD CONDITIONS.
