    (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.

    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

    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

    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%
