Electric baseboard heaters are not supposed to cause soot. However; dust settles on the elements. When the electricity is turned on, the dust will burn off. There will be a trace of soot from that dust.
Some types of dust that are known to be flammable include fine particulate materials like wood dust, coal dust, metal powders, and some organic materials like flour and sugar dust. When these types of dust are suspended in the air in high enough concentrations, they can create explosive conditions if ignited.
Beryllium is primarily found in minerals such as bertrandite, beryl, and chrysoberyl. It is also found in the environment as a trace element in various rocks, coal, soil, and volcanic dust. Beryllium compounds are used in various industrial applications, such as aerospace, electronics, and defense.
True. The vast majority of meteoroids burn up in the atmosphere, and reach the ground only as dust, after drifting around in the atmosphere for some time. (The stuff you wipe off the top of the TV set? Some of it is probably meteor dust.)
Coal has only one advantage relative to oil, which is that it is abundant and relatively inexpensive. Disadvantages include, it is more polluting (due to impurities in the coal) and it is harder to handle; oil can be pumped, whereas coal has to be shoveled. Coal mining is often more difficult and dangerous than pumping oil out of the ground. Coal dust creates the dangers of explosion, and black lung disease.
Coal dust burns fast because it has a high surface area-to-volume ratio, allowing more oxygen to react with the dust particles simultaneously. This increased oxygen availability accelerates the combustion process, causing coal dust to burn quickly.
Coal dust burns faster than solid coal due to its increased surface area, allowing for more efficient combustion. This can lead to more intense and quicker fires when coal dust is ignited.
Coal dust has a larger surface area compared to lumps of coal, allowing for quicker combustion due to increased exposure to oxygen. The smaller particles in coal dust also ignite more easily, leading to faster burning. Additionally, coal dust has lower density and requires less heat to ignite compared to lumps of coal.

A synonym for coal dust could be coal powder or coal ash.
Soot is another word for coal dust.
Coal mines, coal bins, coal hods, and anywhere coal is or was.
Coal dust in the atmosphere is primarily caused by mining, transportation, and handling of coal. Activities such as blasting, crushing, and loading of coal result in the release of dust particles into the air. Weather conditions and wind can also contribute to the dispersal of coal dust in the atmosphere.
Coal workers pneumoconiosis (CWP), is caused by inhaling coal dust.
Coal dust can pose a significant risk of respiratory problems for miners and workers exposed to it, leading to conditions such as black lung disease. Additionally, coal dust is highly combustible and can cause explosions in coal mines if not properly managed. Long-term environmental impacts can also include air pollution and contamination of water sources.
Coal dust in the air is an explosive mixture, because the mixture of coal and air can burn much more rapidly than solid pieces of coal can (flour in the air is also explosive, or sawdust - any flammable substance in the form of dust becomes explosive if it is mixed into the air). The process of mining coal is messy, and creates a lot of dust. And any spark can set it off. No smoking in the coal mines!
There are several nasty things that inhaling coal dust can do but the commonest one was pneumoconiosis.Pneumoconiosis is caused by dust in the lungs usually after prolonged environmental or occupational contact.Anthracosis (an-thrah-KOH-sis),also known as coal miner's pneumoconiosis or black lung disease, iscaused by coal dust in the lungs(anthrac means coal dust, and -osis means abnormal condition or disease.
