Since chimneys are narrow and confined, there’s not enough airflow (oxygen) for proper combustion. When you burn wood or coal in such a place, the partial combustion results in unburnt carbon particles that form soot and creosote
Creosote
Creosote is a category of carbonaceous chemicals formed by the distillation of various tars and pyrolysis of plant-derived material, such as wood or fossil fuel. They are typically used as preservatives or antiseptics.
