Does coal dust burn fast?
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.
Why is an explosion is more likely to occur with coal dust than with lumps of coal?
Coal dust particles have a larger surface area compared to lumps of coal, allowing for faster combustion and easier ignition. The dispersed nature of dust particles also creates more opportunities for them to come into contact with an ignition source, increasing the likelihood of an explosion.
Why does coal dust burn so fast?
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.
Why is coal broken and grounded into powder before it is blown into the boiler blast furnice?
The fine coal dust is much more combustible than large lumps of coal. Large lumps of coal takes time for the flames to begin burning it efficiently - so heat takes longer to build up in the furnace.
What is a synonym for coal dust?
A synonym for coal dust could be coal powder or coal ash.

When the south's supply of coal was gone people formed hard lumps of coal dust sawdust sand and wet clay to burn for heat what were they called?
fireball
What element in the air is needed for coal dust to burn?
Oxygen is the element in the air that is needed for coal dust to burn. When coal dust is exposed to oxygen and heat, it can ignite and burn.

Another word for coal dust?
Soot is another word for coal dust.
Coal dust burns faster than a single lump of coal?
Yes, coal dust burns faster than a single lump of coal because it has more surface area exposed to oxygen, allowing for quicker combustion. This increased surface area allows for more efficient burning and a faster release of energy.
Why it is more difficult to burn some combustible substances than others?
There are many variables which affect the ease of combustion. The degree of mixing with the air is a very large factor. Powdered coal dust in air will ignite explosively, while lumps of coal are much harder to ignite. Different compounds have different activation energies for combustion and there require different temperatures to ignite. Sometimes combustible materials are mixed with non-combustible materials which also makes them harder to burn; for example, dry paper burns quite well, but wet paper is very difficult to burn.
Where is coal dust found?
Coal mines, coal bins, coal hods, and anywhere coal is or was.
What are the causes of coal dust in the atmosphere?
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.
