WOOD COAL Meaning and
Definition
-
Wood coal, also known as peat or lignite, is a fossil fuel formed primarily from decaying plant matter found in wetlands and bogs. It is an early stage in the formation of coal and is considered to be the lowest rank of coal based on its carbon content.
Wood coal is characterized by its brownish-black color and fibrous texture. It contains a high moisture content, typically ranging from 70% to 90%, which contributes to its relatively low energy density compared to other types of coal. As a result, wood coal has a lower heating value and burns less efficiently than higher-ranked coals.
Wood coal is primarily composed of plant remnants such as roots, stems, leaves, and spores, which have undergone varying degrees of decomposition. The process involves the accumulation of these organic materials in water-saturated environments over long periods of time, creating anaerobic conditions that inhibit complete decay and promote the preservation of organic compounds.
While wood coal has been historically used as a source of fuel, particularly in regions lacking access to other energy sources, it is relatively less efficient and produces higher levels of pollutants compared to higher-ranked coals. As such, it is commonly used in small-scale heating or for domestic purposes rather than in industrial applications.

The word has remained relatively unchanged throughout history and is used to refer to the hard, fibrous substance that constitutes the stems and branches of trees.
2. "Coal" comes from Old English "col", which can be traced back to Proto-Germanic "kulą" and Proto-Indo-European "gwl̥h₁-", meaning "burn, heat". The word has been used to describe the black, combustible, carbonaceous rock formed from plant remains that have undergone decomposition over millions of years.
