Waste Coal Transformed into Eco-Friendly Fuel for Steel Production
High volatile coal fines can be turned into coal briquettes to save resources and protect the environment. A blend of coal tar pitch and molasses was used as a binder to make strong briquettes. Ventilation drying improved bonding strength. Briquettes need to be processed in a protective atmosphere due to low combustion temperature. Molasses enhances briquette strength. Ventilation drying makes briquettes stronger than static drying. With the right binder ratio, briquettes meet the requirements for ironmaking.
