The replacement of pulverised coal injection (PCI) coal with hydrogen in blast furnaces looks like being an early decarbonising application. Lower-cost PCI coal is injected into blast furnaces to reduce coking coal consumption. Essentially high-quality thermal coal, PCI coal can be sold into either the metallurgical or thermal coal markets.
Coal is crushed to desired fineness between spheres or cylindrical rollers. After that, air from the boiler is heated to around 330°C (650°F). The raw coal is then fed into the pulverizer where it is ground into fine coal particles. What are the Advantages of Pulverized Coal? Pulverized coal produces a larger amount of heat than traditional coal.
