While combustion processes involving soot have been widely employed for many years, their great complexity puts them beyond present capacity to understand or model reliably. Within a flame, soot plays an important role in radiant heat transfer, and hence in energy efficiency. Beyond a flame, soot can either be emitted as an unwanted air pollutant or as a desirable source of nano-particles, depending on the application. The benefits to society from improved understanding and predictive capability include reduced air pollution, improved health and safety, increased efficiency in the utilisation of both fossil and alternative fuels, the support of the rapidly growing sector employing carbon nano-particles and increased fire safety.

虽然涉及烟灰的燃烧过程已被广泛使用多年，但其巨大的复杂性使其超出了目前的理解或可靠建模的能力。在火焰内，烟灰在辐射热传递中起着重要作用，因此在能量效率中起着重要作用。除了火焰之外，烟灰可以作为不需要的空气污染物或作为纳米颗粒的理想来源排放，这取决于应用。提高理解和预测能力对社会的好处包括减少空气污染，改善健康和安全，提高化石燃料和替代燃料的利用效率，支持使用碳纳米颗粒的快速增长部门，以及提高消防安全。
