Currently, fossil fuels such as coal, natural gas and oil, represent the main energy sources in the world for providing heat. Environmental damage, due to the use of fossil fuels, such as global warming, acid rain and smog, push the world to reduce carbon emissions and to promote the development of renewable energy resources.

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 …

It is a learning process, as anthracite coal burns entirely different than wood or bituminous coal. To begin, take around eight sheets of newspaper, crumble into balls and place on the top of the grates in your stove. Next, lay fine kindling on top of the paper. The kindling must be dry and no larger than ¾" in diameter.

Anthracite is hard coal. It is the oldest type of coal-that is, it took nature the longest to form. It burns the most steadily and cleanly and the longest of all coal. It has the highest carbon content and thus has the highest heat content of all coal. It is also the shiniest and is often called "black diamonds"

The production of pelleted feed is a complex and expensive activity. Optimising the manufacturing process is therefore important to maintain production profitability, making it necessary to collect all relevant data along the processing chain. It is also essential to understand the parameters that affect the pelleting process.
