As an expert in the field of combustion and emissions, I can provide an insightful explanation regarding the nature of soot and ash.
Soot is a black carbon substance produced by the incomplete combustion of hydrocarbons, typically found in the exhaust of diesel engines and other combustion processes. It consists of small particles of carbon, which are spherical in shape and can be harmful to the environment and human health. These particles are very fine and can easily be inhaled into the lungs, potentially causing respiratory problems. Soot is also known as particulate matter (PM), and it is a significant contributor to air pollution.
Ash, on the other hand, is the residue that remains after the complete combustion of organic materials. It is composed of inorganic salts and minerals that were part of the original material. Ash is not combustible and does not contribute to air pollution in the same way as soot does. It is often a white or light gray powdery substance and is generally considered a waste product that needs to be managed and disposed of properly.
The distinction between soot and ash is important in various applications, particularly in the context of emissions control. Diesel particulate filters (DPFs) are designed to capture soot particles from the exhaust stream, preventing them from being released into the atmosphere. However, ash, being incombustible, does not accumulate in the DPF in the same manner as soot does. Instead, ash must be managed through other means, such as regular cleaning or disposal processes.
It is also interesting to note the difference in particle size between soot and ash. Soot particles are typically much smaller than ash particles, as illustrated in the comparison figure provided. This size difference can affect how they are captured and managed in various systems.
In summary, while both soot and ash are byproducts of combustion processes, they have distinct characteristics and require different handling methods. Soot is a fine, black, carbon-based particulate matter that is harmful to health and the environment, while ash is an incombustible residue composed of inorganic salts and minerals.

Ash, on the other hand, by definition is incombustible and must be removed from the DPF through some type of cleaning process. Figure 1: Comparison of soot and ash agglomerate particle size. Soot particles form in the engine's combustion chamber as the result of incomplete combustion.
