Detailed information is available in our dedicated Coal, Coke & Iron Ore Testing Furnaces brochure (please download above).
Carbolite has developed a range of coal and coke testing furnaces and ovens for proximate analysis to qualitatively assess or, quantitatively measure, the amount of moisture, ash, volatile matter and fixed carbon in coal samples. Other products are also available for the determination of coke reactivity, iron ore reducibility, ash fusibility, swelling number index, expansion and contraction of coal and caking properties.
The range of coal and coke tests carried out in a furnace or oven has grown over many years, and Carbolite has responded to the requirements of each new standard by designing a product to suit the specific requirements of each test method.
The range includes bench top laboratory models for routine testing and large pilot plant scale products, some of which are unique to Carbolite, such as the variable width hearth moving wall coking oven which can be found in coal research facilities as well as large steel producing plants around the world.
The Carbolite range of products meets the requirements of the relevant international ISO, ASTM, EN, BS, and DIN test methods.

Determining the CO2 reactivity of petroleum coke
Calcinated petcoke is an essential ingredient in the production of aluminium. Its quality needs to be monitored continuously throughout the production process to ensure a high quality metal grade. As part of its range of coke testing furnaces, Carbolite has designed a special model for determining the CO2 reactivity of petroleum coke in accordance with ISO 12981-1. The furnace has a single, vertical, tubular heating zone which is integrated into the unit, giving a neat and compact design overall.
How coke is created in a coal testing oven or pilot plant
Thanks to huge advances in metallurgy over the last three decades, 21st century steel production is transforming the globe and the built environment. Of course, a major part of the steel production process is the use of coke, which provides as much as 80% of the furnace's thermal requirements, the majority of the furnace's CO gas (which acts as a reducing reagent) and carbon for dissolution in the molten metal. As with any other manufacturing process, the quality of the raw material has a massive impact on the quality of the end product. It is therefore vital to ensure the coke is comprehensively tested.
