An essential & comprehensive course on coal analysis, international standards, coal sampling, laboratory analysis, instrumental analytical techniques coal blending & related coal safety issues


Note From Trainer

Each year, billions of tonnes of coal are traded in national and international markets for use in power generation, steel and cement production, plus several other sectors.

The price of coal not only reflects the quantity of coal but also reflects the relationship of one or more properties to the performance of the coal under operating conditions.

The properties of coal often form the basis of sale contracts – and the payment for the coal is based on the analytical results.

Coal is a very heterogeneous material containing various organic and inorganic (mineral) matter – and therefore exhibits a wide range of physical properties.

The analysis of coal is generally performed on the coal samples taken from the bulk material and not from the individual components. Given the complexity of coal, sampling protocols must provide material that is representative of the cargo being sampled.

To ensure that a representative sample is collected, correct sampling procedures and rules should be followed. Also, coal analyses should be sufficiently accurate so as to preclude negative scientific or economic consequences.

All coal analyses should follow standard procedures in order to obtain repeatable and reproducible results. This course reviews the various aspects of coal sampling and analysis. It provides descriptions of standard procedures for coal sampling, preparation and routine testing of coal specified in the international Standards.

The commonly used techniques for routine coal analysis and recent developments are also examined.Blending of imported and domestic coal is becoming of increasing importance.

Until recently, coal blending in power stations was mainly adopted to reduce the cost of generation and increase the use of indigenous or more readily available coal.

Lower-grade (higher ash) coal can be mixed with higher grade (imported) coal without deterioration in thermal performance of the boiler – thus reducing the cost of generation.

In some cases coal blending is used as a form of pollution control, such as the combination different coals to ensure compliance with sulphur emission limits.

Many methods of coal blending are used. Coals can be blended at the coal mine, at the preparation plant, trans-shipment point, or at the power station.

The method selected depends upon the site conditions, the level of blending required, the quantity to be stored and blended, the accuracy required, and the end use of the blended coal.

This course examines the different reasons and priorities for coal blending. These include the methods used in coal blending, from coal characterisation though to mixing and storage methods, including some case studies in challenging situations.

There are several related safety issues that plant operators should evaluate when handling and storing coal.

Self-heating and spontaneous combustion can be a significant problem in the global coal industry – not only due to the obvious safety hazards and the potential loss of valuable assets – but also with respect to the release of gaseous pollutants from coal fires.

Basic policy and risk assessment measures that plant operators should adopt are reviewed in this course.

Key stages in coal transport, handling and storage are separately examined – ranging from coal handleability problems, vessel-related issues, coal stockpiles, conveyor belts and coal silos.

Current best practice covering safety and plant operation is included.
