Candle coal refers to a specially processed type of coal that has unique properties, primarily used for heating and lighting purposes. It is a compact and dense form of coal that is commonly shaped into small cylindrical or hexagonal pieces resembling candles, hence its name.
Candle coal is typically produced by compressing finely ground coal particles under high pressure, which removes most of the volatile substances and moisture content. This results in a cleaner-burning and more efficient fuel source compared to raw coal.
The composition of candle coal may vary depending on the region and coal source, but it generally consists of carbon, hydrogen, oxygen, nitrogen, and trace elements like sulfur and ash. It possesses a high carbon content, which contributes to its high energy yield when burned.
Due to its compact form and energy density, candle coal has been traditionally used as a fuel for heating homes, providing warmth during colder months, and for lighting purposes such as fuel for lamps or lanterns. It offers a long-lasting and steady source of heat and light, making it a popular choice in areas where electricity may be unreliable or unavailable.
In modern times, candle coal has been gradually replaced by alternative energy sources due to environmental concerns and advancements in technology. However, it still holds cultural and historical significance, and can be seen in certain traditional practices and in nostalgic representations of the past.
