Product Overview
This high-temperature coal reactivity determination system is engineered for evaluating the chemical reactivity and gasification kinetics of coal, semi-coke, and metallurgical coke when exposed to carbon dioxide. Designed in strict compliance with standardized analytical protocols such as GB/T 220-2001, the equipment delivers accurate quantification of fuel reduction capability and carbon conversion dynamics. By establishing a strictly regulated thermal environment and controlled reactant contact, this specialized test bench empowers fuel processing facilities, research laboratories, and metallurgy plants to accurately characterize how carbonaceous solid fuels behave in industrial gasifiers, blast furnaces, and direct reduction shafts.
Built to withstand continuous high-temperature demands, the testing apparatus serves critical evaluation workflows across the coal extraction, synthetic chemistry, power generation, construction material, metallurgical, and geological survey sectors. Modern coal conversion processes, such as fluidized bed gasification, entrained flow conversion, and pulverized coal injection, require precise empirical data regarding fuel reaction velocity, surface area accessibility, and gasification efficiency. This instrument provides researchers and process engineers with repeatable kinetic profiles that guide fuel blending optimization, specific coal consumption reductions, and overall syngas yield maximization.
Engineered with an advanced silicon carbide tubular heating core, high-purity thermal insulation linings, and noble metal sensing feedback, this furnace configuration maintains an expansive and strictly uniform isothermal soaking zone under high-throughput operation. The robust mechanical structure and integrated digital control system ensure exceptional thermal boundary management, zero draft interference, and prolonged structural longevity. Operators gain unwavering confidence during critical fuel quality control assessments, ensuring reproducible reaction indices and dependable analytical throughput across intensive industrial testing schedules.
