when coal is pulvorised(powder ) the surface area will be more so it cathes fire early than lumps.
Lumps of Coal
Traditionally - lumps of coal.
Pineapple Lumps was created in 1935.
Lumps of Coal
Lumps of coal can be purchased at science shops, such as the ones where you would buy science kits for children. Also, if you have a year-round Christmas store, they often have lumps of coal as gag gifts.
I can see !
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.
It was as different as diamonds are from lumps of coal.
I can see!!
Powdering the coal vastly increases the surface area. As a result, the coal burns more evenly, predictably, and cleanly, with fewer off-gases and less waste.
The coal dust burns more quickly because it has a greater surface area to be exposed to the flames of the fire, therefore it burns quicker than the lump of coal.
