What is BS 1016-108.6 - Determination of critical air blast value about?

BS 1016 is a series on methods for the analysis and testing of coal and coke. Coal and coke are grey, hard, and porous fuels with high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process.

It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern. BS 1016-108.6 describes a method for the determination of the critical air blast value of coke.

Who is BS 1016-108.6 - Determination of critical air blast value for?

BS 1016-108.6 on the determination of the critical air blast value is useful for:

Coal mining stations
Fuel production industries
Petroleum industries
Quality control personnel

Why should you use BS 1016-108.6 - Determination of critical air blast value?

The unqualified term "coke" usually refers to the product derived from low-ash and low-sulphur bituminous coal by a process called coking. The critical air blast value is a measure of the reactivity of coke to air. The more reactive the coke the lower its critical air blast value. Typical values are 0.4 l/min for low-temperature coke and 1.8 l/min for high-temperature coke.

BS 1016-108.6 states that A bed of graded coke is ignited electrically in a specified combustion chamber, with dry air passing through the bed at a rate of 4.25 l/min. When the coke has fully ignited the rate of airflow is reduced to a preselected value for 20 min and then raised to the original value to attempt resuscitation. This procedure is repeated with fresh portions of the coke and with other rates of airflow until the critical value is found. Using BS 1016-108.6 you can describe a method for the determination of the critical air blast value of coke.
