Coke
Coke is a kind of solid fuel. Coal is obtained by dry distillation at a high temperature of about 1000 degrees C. The main components are fixed carbon, followed by ash, containing very little volatile and sulfur. Silver-grey with a metallic sheen. Hard and porous.
Most of its heat is 26380 to 31400kJ/kg (6300 to 7500kcal/kg). According to different uses, there are three categories of metallurgical coke, casting coke and chemical coke. By size, there are pieces of scorched, crushed and scorched chips. It is mainly used for smelting steel or other metals and can also be used as raw materials for the manufacture of water, gas, gasification and chemical industries.
