Hello everyone, what are the gas components of blast furnace gas? Please provide the specific percentage. Could that expert give an answer?
Volume ratio: hydrogen 1.5%, methane 0.2%, carbon monoxide 28%, carbon dioxide 11%, nitrogen 57.8%, oxygen 0.3%; the remainder are impurities
Friend upstairs, thank you so much! :handshake
Blast furnace gas contains a relatively high proportion of carbon dioxide and nitrogen.
Gas composition and percentages (%) of blast furnace gas: Hydrogen (H2) 1.5~3.0, Methane (CH4) 0.2~0.5, Carbon monoxide (CO) 25~30, Carbon dioxide (CO2) 9~12, Nitrogen (N2) 55~60%, Oxygen (O2) 0.2~0.4; the remainder are impurities (dust, etc.)
In fact, the composition of blast furnace gas varies from blast furnace to blast furnace. For example, CO and CO2 have quite significant differences in their composition. For example, the composition of the BFG from a certain blast furnace is as follows: CO 21.83%, CO2 20.64%, H2 2.45%, CH4 0.01%, N2 47.6%, and H2O 7.47%. The higher the CO content, the higher the calorific value of the BFG; however, this also indicates that the efficiency of the blast furnace is low.
What is a blast furnace used for? Is it a fluidized bed? Is the coal burned completely or vaporized?
