What is a Coal Coke Breeze? - Definition from

19/03/2015  The fuel used in the iron ore sintering processes is coke breeze. Its combustion yields high enough amounts of heat which is delivered to the sinter mix. Corrosionpedia explains Coal Coke Breeze. In the coal coke production process, during the coke quenching, handling and screening operation, coke breeze is produced. It is either reused on site (such as in the sinter plant) or sold off

APPLICATION OF FINE-GRAINED COKE BREEZE FRACTIONS IN

The fuel used in iron ore sintering processes is coke breeze. Its combustion yields enough amounts of heat which is delivered to the sinter mix. One of the factors that signifi cantly affect the course of coke breeze com-bustion is its grain size. Many studies and industrial practices have shown that coarse-grained coke breeze causes delayed combustion, which leads to higher heat energy ...

Coke (fuel) - Wikipedia

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...

KOBELCO Pelletizing Process

sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into product pellets. The pellets are used as the raw materials not only for blast furnaces but also for gas-based direct reduction ...
