Coal is a critical resource used in many areas, from energy production to production. However, not all coal is equal, and understanding quality coal is important for effective and efficient use. In this article, we will focus on how you can understand coal based on its visual and chemical properties.
Understanding Appearance Quality: Shine and Durability When buying coal, the first two important visual features to pay attention to are its durability and durability.
Shine: Reflection Indicates Quality production usually has a shiny game. This part indicates that the amount of carbon the coal can produce is high and will burn more efficiently. Dull or dull coals can usually be of lower quality or moist.
Durability: Indicator of strength The physical performance of the coal gives important clues about its quality. Quality coal does not crumble or break easily when held in the hand. If the coal is easily scattered or turns into dust, this may be a sign of lower quality production.
Chemical Properties: Nitrogen, Moisture, Volatiles and More For the secrecy of coal, not only physical properties but also chemical components should be seen.
Nitrogen Content: Chemical Indicators of Quality The carbon ratio in coal varies depending on the type of coal and its formation forms. Since carbon plays an important role in the combustion process, it is one of the indicators of quality coal. For example, lignite coal usually contains 25% – 35% carbon, hard coal usually contains 45% – 85% carbon, anthracite contains 85% – 98% carbon by weight. These ratios play an active role in determining production, coal properties and combustion efficiency among coal types.
Humidity, Volatile Substances, Sulfur and Ash Other important characteristics of quality coal include low humidity, appropriately sized contents, small amounts of sulfur and ash. While high humidity changes as a result of combustion, high temperature substance content provides faster and more effective combustion. Low sulfur formation, reduced reactive effects and ash amount ensure that activation is low after coal combustion.
Calorific Values: Energy Efficiency Finally, the calorific value of coal shows how much energy will be produced during combustion. Coals with high calorific value provide more efficient energy production and are generally considered to be of higher quality.
Quality distribution is possible with visual presentations and chemical analyses. Brightness, durability, nitrogen content, moisture and porous material ratios, sulfur and ash content and calorific value play a key role in determining the characteristics of coal. By paying attention to these parts, we store the most suitable coal for your needs.
