燃气轮机条件下氨燃烧NOx排放特性的多维参数分析
Multi-dimensional Parameter Analysis of NOx Emission Characteristics of Ammonia Combustion Under Gas Turbine Conditions
摘要
Abstract
Ammonia(NH3)is a promising carbon-neutral fuel.To clarify the NOx emission of ammonia rich-quick mix-lean(RQL)combustion with multiple parameters and overcome the single-parameter limitations of conclusions,this study establishes a five-dimensional parameter matrix(primary equivalence ratio,hydrogen blending ratio,inlet temperature,residence time,and pressure),including 11 760 cases.Reactor network simulations are conducted to investigate ammonia RQL combustion.The results indicate that,reducing the sum of NH3 and NOx in primary combustion products is critical for lowering overall NOx emissions.The primary residence time simultaneously increases or decreases NH3-NOx levels in primary products,enabling independent optimization.Primary equivalence ratio,hydrogen blending ratio,and inlet temperature induce opposing changes(one increases while the other decreases)in NH3-NOx levels,necessitating coordinated adjustments.Pressure exhibits non-monotonic variations.This study demonstrates that staged combustion emissions is controlled by primary NH3 and NOx,and simplifies parameter optimization principles through parameter classification.The findings provide insights into ammonia staged combustion mechanisms and can guide combustion optimization strategies.关键词
