The primary pollutants from combustors are carbon monoxide (CO), carbon dioxide (CO₂), NOx, and unburned hydrocarbons (UHC) among other particulate emissions. All of the above cause significant damages to the environment¹ and/or the biological species residing in it.^2–5 The combination of these pollutants cause a wide variety of issues in humans, mostly involving increased mortality, reduced capacity to absorb oxygen by the blood cells, asthma, other severe respiratory diseases, heavy metal poisoning, kidney failure, etc.⁶ As a consequence of this, there have been systematic efforts to reduce emissions from combustor elements. A case in point is the targeted goal of reducing CO₂ by 75% by the year 2050, as put forth by the Advisory Council for Aeronautical Research in Europe.⁷ Considering that a significant majority of these emissions are produced by gas-turbines, owing to their providing 10% of all power generation in the US (aviation included),⁸ it is essential to understand and treat the production of gaseous emissions as we move forward. Emissions reduction should be construed as a parallel effort that is needed in conjunction with increasing the thermal efficiency of these engines—a 1% increase is tantamount to removing 1,360,000 cars off the roads.⁸ Traditionally, owing to the drastic changes in the combustor operating conditions, different engines tend to produce rather different levels of pollution. The following equation represents the commonly used quantification process to estimate emissions from an aircraft engine, depending on its phase in the landing–takeoff cycle⁶

各种增压燃烧室污染物排放的综述

来自燃烧室的主要污染物是一氧化碳（CO），二氧化碳（CO ₂），NOx和未燃烧的碳氢化合物（UHC）等其他颗粒物排放物。以上所有对环境¹和/或居住在其中的生物物种造成重大破坏。^2-5这些污染物的原因各种各样的在人类中，问题大部分涉及死亡率增加的结合，降低了血细胞，哮喘吸收氧气的能力，其它严重呼吸道疾病，重金属中毒，肾功能衰竭等等^6个作为因此，已经进行了系统的努力以减少燃烧器元件的排放。一个典型的例子是减少CO _2的目标。根据欧洲航空研究咨询委员会的建议，到2050年将减少75％。⁷考虑到这些排放物中的绝大部分是燃气轮机产生的，因为它们提供了美国所有发电量的10％（包括航空业），⁸因此，在我们搬迁时，必须了解并处理气体排放的产生前锋。减少排放应被认为是与提高这些发动机的热效率相伴而生的一项并行努力，即增加1％相当于减少1,360,000辆汽车的上路行驶。⁸传统上，由于燃烧器运行条件的急剧变化，不同的发动机往往会产生相当不同的污染水平。以下等式代表了估算飞机发动机排放的常用量化过程，具体取决于其在着陆-起飞周期中的相位⁶
