How small the particles need to be depends on a number of factors that influence the overall combustion rate. For pulverized coal combustion applications the particle size should be less than 75µm [7]. Coal can relatively easily be crushed to small particles, while this becomes much more energy intensive for e.g. wood.

Why Pulverized Coal is Used in a Power Plant

Coal for Power Plants. The coal fired power plant converts energy in coal to electricity. The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant.

Pulverized Coal System Advantages and Disadvantages - Melezy

Jul 8, 2021Advantages of pulverized coal firing (1) Greater surface area per unit mass of coal allows faster combustion reactions because more carbon becomes exposed to heat and oxygen. This reduces the excess air needed to complete combustion. (2) Less excess air is required for complete combustion because of greater surface area of fuel exposed.

What are the types of coal? | U.S. Geological Survey

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

Generally produces less ash and so can be less prone to suffocate your coal bed. (The better quality lump is from all wood and so doesn't have the additives that regular charcoal briquettes can have. (You can get all natural briquettes also, which will produce less ash than even decent briquettes, like Kingsford blue).
