What is coke breeze made from?
coal
Whereas petcoke is a byproduct of heavy crude oil refining, coke breeze is usually made from coal.
What is nut coke?
Nut Coke means coke otherwise meeting the quality specifications in Schedule A and of a size equal to or greater than 3/8 inch and less than 3/4 inch.
What is metallurgical coke?
Metallurgical coke is produced by destructive distillation of coal in coke ovens. The material remaining is called coke. Most metallurgical coke is used in iron and steel industry processes such as blast furnaces, sinter plants, and foundries to reduce iron ore to iron.
Is coke breeze hazardous?
Symptoms Related to the Physical, Chemical and Toxicological Characteristics: May cause irritation if inhaled. Potential Health Effects (Acute, Chronic and Delayed): Inhalation: May cause irritation, chronic inhalation of coke may cause bronchitis.
What are coke furnaces?
The industrial production of coke from coal is called coking. The coal is baked in an airless kiln, a “coke furnace” or “coking oven”, at temperatures as high as 2,000 °C (3,600 °F) but usually around 1,000–1,100 °C (1,800–2,000 °F).
Why coke is used in blast furnace?
Publisher Summary. Metallurgical coke, along with iron ore and limestone, is layered into a blast furnace to convert the iron ore to metallic iron. Coke, which is mostly carbon, reacts with the blast air to produce carbon monoxide, which, in turn, reacts with the iron oxide to produce carbon dioxide and metallic iron.
Why nut coke is used in blast furnace?
Nut coke (size < 40 mm) is charged in mixture with the ferrous burden in the blast furnace to take advantage of better permeability, enhanced reduction kinetics and to lower the expensive regular coke requirement during smelting. Nut coke is charged in wide range of size 10 – 40 mm and concentration from 2 – 35 %.
What is Otto Hoffman Process?
Manufacture Of METALLURGICAL COKE By Otto-Hoffmann’s By Product Oven Process:- The process of preparing coke from coal is known as carbonization of coal. When bituminous coal is heated strongly in the absence of air, the dense strong, porous mass obtained is called metallurgical coke.
What is the purpose of coke in steel making?
In the steel-making process, coke is used in the blast furnace as a (1) fuel to produce added heat; (2) chemical-reducing agent for the reduction of iron oxides; and (3) as a permeable support in the molten material in the furnace.
What is coke breeze backfill?
Petroleum coke breeze is a carbon backfill which is used around impressed current anodes for underground cathodic protection applications. It is used to: Reduce the resistivity of the environment surrounding the anode to increase the amount of current the anode can discharge.
Is coke dust flammable?
Coke Dust is Combustible and is an Explosion Hazard: A potentially catastrophic hazard which must be controlled in coke handling operations is the possibility of a combustible dust explosion or deflagration.
What is coke vs coal?
Coal is a lustrous, black fossil fuel that includes impurities, generates smoke, and generates less heat than coke when burned. Coke is a dingy, black coal waste that burns hotter and cleaner. Despite the fact that coal is not a renewable resource, it is widely used to create power.
