(blast furnace gas and coke oven gas) is supplied to related processes and power stations. Therefore, in order to reform the energy struc-ture of the iron and steel industry, it is first necessary to review the raw materials and reducing agents used in blast furnaces. In addi-tion, the industry is urged to respond effectively to the present state
Coke oven gas (COG) is a byproduct of the coke-making process consisting of a complex mixture of typically 55 % H2, 7 % CO, 25 % CH4 and small amounts of CO2, H2O, heavy tars and volatile hydrocarbons. Today, most COG is used for heating applications, as a chemical plant feedstock or is flared, leaving its potential as a reducing gas untapped.
4 Saving in Everything We Do Sep-2010 7 • Coke ratio at Corex was lowered by 6.7%. This was achieved by better heating regime and consistent coal availability. • Coke rate at blast furnace was lowered by 9.3% by increasing the PCI. This was achieved by increased availability of Blast furnace

Storage Store in an area protected from freezing. Precaution Avoid prolonged or repeated contact. Avoid contact with skin and eyes.
Coke had been widely adopted for use in blast furnaces by the mid-18th century, and the principle of heating air before it entered the furnace was introduced in the early 19th century. Modern blast furnaces range in size from 20 to 35 m (70 to 120 feet), have hearth diameters of 6 to 14 m (20 to 45 feet), and can produce from 1,000 to almost
Non blast furnace ironmaking technology process is currently a supplementary system, and there is certain room for development in the future. To reduce the coke rate and to reduce carbon dioxide emissions as the main goal, it needs to reform the existing blast furnace ironmaking process, explore a new technology to radically reduce emissions of
DRI from Coke Oven Gas Effective use of COG beyond simple heating value Coke Oven – EAFs account for ~97% of DRI consumption today (74MM tpy) Blast Furnace: Use of HBI in Blast Furnaces is not new o 10% charge of metallic iron increases BF productivity by 8% and decreases fuel rate by 7%

The main function of Coke Ovens is to convert coal into coke which is used as a fuel and reducing agent in the Blast Furnace. Its secondary function is to recover Volatile Matter and CO (Coke Oven) gas from coal and extract chemicals known as Coal Chemicals. CO gas produced is used for heating purposes in the plant. Heat from hot coke is
Coke oven gas is formed by heating coal to 1100 °C without access of air. The classic composition of coke gas: hydrogen (H2 - 51%), methane (CH4 - 34%), carbon monoxide (CO - 10%), ethylene (C2H4 - 5%). The composition may also include benzene (C6H6), ammonia (NH3), …
injection of natural gas in blast furnaces, • In 2013, all but 1 of 29 of NAFTA blast furnaces are injecting gas while 45 % are co injecting with gas and PCI, while one coal injection system (to serve 2 BF's) remains idle • Natural gas is cheaper than coal at many but not all BF sites; continued use of coal maximizes total coke replacement
Feb 02, 2011 · COKE-OVEN GAS. Coke-oven gas is a fuel gas having a medium calorific value that is produced during the manufacture of metallurgical coke by heating bituminous coal to temperatures of 900°C to 1000°C in a chamber from which air is excluded. The main constituents are, by volume, about 50% hydrogen, 30% methane and 3% higher hydrocarbons, 7%
