Hard Coal Laboratory Services

Hard Coal

The Hard Coal industry, also known as the anthracite coal industry, focuses on the extraction and processing of the oldest and most carbon-rich type of coal available. Known for its high energy content and low emissions, anthracite is primarily used in metal smelting and heating applications. This sector plays a crucial role in energy production, especially in regions where other fuel sources are less accessible.

Hard Coal Testing and Research Services

Contract Laboratory can help you with all your Hard Coal testing, analysis, scientific research and development, inspection, certification, engineering, failure investigation, and product development needs including:

Energy Content Testing: Measures the calorific value of anthracite to ensure optimal energy yield for heating and industrial uses
Emission Testing: Evaluates the emissions produced when anthracite is burned
particularly focusing on sulfur and volatile compounds
Impurity Analysis: Assesses the purity of anthracite
looking for non-carbon elements which could affect its burning properties and applications
Moisture Content Testing: Determines the moisture level in anthracite
which can influence its efficiency as a fuel

Type of Hard Coal Products

Contract Laboratory can assist your company, academic institution, government agency or organization in outsourcing contract laboratories to perform testing, analysis, and product development for many Hard Coal finished products, processes, systems, in-process materials, raw materials and components such as:

Anthracite Coal: High-grade
hard coal with a deep black color and glossy finish used for heating and industrial fuel
Processed Anthracite: Refined or sized anthracite used in various applications including water filtration and as a carbon source in steel production
Anthracite Briquettes: Compressed anthracite coal used for domestic heating and industrial processes due to their high density and long burning time
Activated Carbon: Produced from anthracite
used for purification and filtration processes
Ultra-high-grade Anthracite: Specially processed for use in high-tech applications
such as in the production of silicon and other specialized metallurgical processes
