We discussed the history and applications of coal in our last post. The varieties of coal and the significance of using a bomb calorimeter to analyze coal will be covered in this article. We'll talk about how coal's calorific value affects industrial uses and energy efficiency.
What are the Types of Coal?
1. Peat
Peat consists of rotten plants in low-oxygen and water-filled environments. Coal is the first stage of the formation process. It accumulates in swamps over time, but has not yet undergone significant coal conversion. It has the lowest energy content among the coal types and is therefore less efficient as a fuel source. Dec. It is used for heating in some rural areas and gardening.
Carbon Content: Approximately <60
2. Lignite (Brown Coal)
Lignite, called brown coal, is the second stage of coal formation. Lignite is formed after peat coal has been pressured for millions of years. Its carbon content is higher than Peat, but it still has a lot of moisture. For this reason, because it is inefficient, it is usually used for electricity generation in places close to the area where it is extracted.
Carbon Content: Approximately 65%-70%
3. Subbituminous Coal
This type of coal carries Decarbonized content between Lignite coal and bituminous coal. Its energy efficiency is higher than lignite, but it is not as rich as bituminous coal. It is formed by keeping lignite under higher heat and pressure. Subbituminal Coal is widely used in electricity generation. It contains moderate energy, suitable for short transport distances.
Carbon Content: Approximately 70%-76%
4. Bituminous Coal (Black Coal)
Bituminous Coal is called black coal and is the most widely used type of coal. It is formed by keeping subbituminal coal under more heat/pressure and contains high carbon. That is why its energy density is also high, its color is black and bright. It is the most efficient type of coal for industrial applications. It is widely used in electricity generation, cement manufacturing and steel production.
Carbon Content: Approximately 76%-86%
5. Anthracite (Hard Coal)
Anthracite is the type of coal that is subjected to the highest heat and pressure. It has the highest carbon content and the lowest humidity. That is why it is the hardest and most efficient type of burning coal. Anthracite is used in heating and some industrial processes due to its high energy value. But because the cost is high, it is used less in electricity production.
Carbon Content: Approximately 86%-97%
Analysis of Coal Calorific Values
The analysis of coal calorific values is important from the point of view of energy efficiency. Coal-using industries analyze the energy value of coal,optimize combustion performance and reduce waste. Bomb calorimeters are the devices used for these analyses. This device measures the energy released during the combustion of coal and indicates its energy potential. Thus, it allows for better resource management and can be used efficiently.
At Debye Technic, the Debye Technic IC210 Bomb Calorimeter that we have developed for analyzing the calorific value of coal offers an ideal solution. It optimizes fuel usage and ensures an increase in efficiency.
