Our Services

We offer a wide range of coal testing services, including:

1. Proximate Analysis

• Moisture Content: Determining the amount of water present in the coal.
• Volatile Matter: Measuring the components that are released as gases when coal is heated.
• Ash Content: Assessing the inorganic residue remaining after combustion.
• Fixed Carbon: Calculating the solid combustible residue after volatile matter is removed.

2. Ultimate Analysis

• Carbon (C): Quantifying the carbon content in coal.
• Hydrogen (H): Measuring the hydrogen content.
• Nitrogen (N): Determining the nitrogen content.
• Sulfur (S): Assessing the sulfur content.
• Oxygen (O): Calculating the oxygen content by difference.

3. Calorific Value Determination

• Gross Calorific Value (GCV): Measuring the total energy content of coal.
• Net Calorific Value (NCV): Determining the usable energy content after accounting for moisture and other losses.

4. Ash Fusion Temperature

• Initial Deformation Temperature: Identifying the temperature at which ash begins to soften.
• Softening Temperature: Determining the temperature at which ash becomes fully molten.
• Hemisphere Temperature: Measuring the temperature at which ash forms a hemisphere.
• Flow Temperature: Assessing the temperature at which ash flows freely.

5. Sulfur Forms Analysis

• Total Sulfur: Quantifying the total sulfur content in coal.
• Organic Sulfur: Measuring the sulfur bound within organic compounds.
• Inorganic Sulfur: Assessing the sulfur present in inorganic forms.

6. Trace Element Analysis

• Heavy Metals: Detecting elements like mercury, arsenic, selenium, etc.
• Mineral Constituents: Analyzing major and minor elements in the ash.

7. Hardgrove Grindability Index (HGI)

• Grindability Assessment: Evaluating the ease with which coal can be pulverized, affecting milling efficiency.

8. Coke Reactivity Index (CRI) and Coke Strength after Reaction (CSR)

• CRI: Assessing the reactivity of coke during combustion.

CSR: Measuring the strength of coke after exposure to reactive gases
