Soot: An Invisible Enemy to Safety & Efficiency Soot is a black, powdery residue composed primarily of carbon formed when organic materials, such as wood, coal, oil, or gas, burn incompletely. It is commonly produced in combustion systems like chimneys, stoves, boilers, and internal combustion engines. Soot can accumulate on the interior surfaces of these systems and in ventilation ducts, reducing energy efficiency, obstructing airflow, and increasing the risk of fires if not properly removed. Therefore, regular soot cleaning is crucial for maintaining the safety and proper performance of combustion equipment.
