In order to obtain comprehensive evaluation results of PCs and their applicability to blast furnaces, the employed test equipment should reproduce the fundamental features of the pulverised coal injection (PCI) process. Currently, PC performance in blast furnaces is evaluated in diverse equipment or test reactors.

Analysis and significance of mineral matter in coal seams

Analysis and significance of mineral matter in coal seams

Analysis of raw coals avoids the need for a preliminary ashing process, but is less sensitive than analysis of mineral concentrates, such as LTA residues, to minerals present in low proportions in the coal samples. It may also be difficult to distinguish irregularly interstratified clay minerals from the organic background in some instances.

The injection of coal through tuyeres into a blast furnace is widely adopted throughout the industry to reduce the amount of coke used and to improve the efficiency of the iron making process. Coals are selected depending on their availability, cost, and the physical and chemical properties determined by tests, such as the volatile matter content, fixed carbon, and ash content.

A coal testing procedure undergoes mainly two types of testing Proximate Analysis and Ultimate Testing. The 'proximate analysis' includes the testing of Moisture, Ash, Volatile Matter, Fixed Carbon. The fixed carbon plays an important part in the burning of coal, whereas volatile matter plays a significant part in the ignition of fuel.
