Example 2.1 Combustion ofOctane in Air Detennine the stoichiometric fuel/air mass ratio and product gas composition for combus tion ofoctane (CSH1S ) in air.The equipment will be the key components of a blast furnace gas (BFG)fired gas turbine combined cycle (GTCC) power plant with a 180 MW output. Operations are scheduled to
Blast Furnace Gas (BFG) is the key fuel source used at the combustion boiler to generate steam. The steam is used in various plant processing and is used by the steam generator to produce electrical power. There are : three power houses, each with five to seven boilers. BFG feed has two issues, the incoming flow rate is variable, and it'sbricks. The main fuel used for hot stove combustion is the Blast Furnace Gas (BFG), which is enriched with Coke Oven Gas (COG) in order to get the required brick temperature. With the completion of the ongas cycle, the system proceeds to the stove change stage to purge the flue gas. Thereafter, it switches to the onblast cycle.
A European funded project aiming to enhance the usage of blast furnace gas (BFG) in steel reheating furnaces has been successfully accomplished by a multidisciplinary international consortium ofFurnace gas for power production. Furnace gas is a gas which is produced in different types of furnace during the production of metals. High levels of power requirement and rising energy costs present a major challenge to the metallurgical industry.
Blast Furnace Gas (BFG), Coke Oven Gas (COG), and BOF Converter gas as well as mixtures beneficiated with natural gas. While these fuels have been commonly in use since the early years of steel production, recent environmental concerns regarding NO x and CO 2 emissions represent a new technological challenge in this appliion. Modern modelingBlast furnace gas topic. An early internal combustion blowing engine of around 1900, powered by furnace gas Blast furnace gas (BFG) is a byproduct of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron.
PDF Pilot trials at MEFOS have proven that a new S3 blast furnace gas (BFG)oxyfuel burner can give high performance, low NOx, low cost reheating for the steel industry. The S3 burner has beenBlast Furnace Gas. Blast furnace gas is a byproduct of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around 0.9kWh/Nm 3, which on its own is typically not high enough for combustion in a gas engine. There is the possibility to blend this gas with other off gases and you
Blast Furnace gas generation and usage. Blast furnace (BF) gas is a gaseous by product which is generated while producing hot metal (liquid iron) in a blast furnace. The operation of the blast furnace is controlled to produce hot metal of a specified quality and during this production BF gas comes out from the furnacemonoxide has declined considerably. By virtue of blast furnace gas purifiion, the dust and sulphur dioxide emissions are also significantly below the permissible limits. Because the lean gas replaces a substantial amount of natural gas, its combustion saves enormous costs so that a new facility pays off within an extremely short period of time.

It has a very low heating value, about 93 BTU/cubic foot (3.5 MJ/m 3), because it consists of about 60 percent nitrogen and 18
Particularly, Blast Furnace Gas (hereinafter abbreviated as BFG) is byproduct gas from steel work and its amount is huge. Therefore, there is a strong requirement to utilize BFG for high efficiency and large capacity Gas Turbine. Compared with natural gas, BFG vary in hydrocarbon composition, physical properties, impurities and others.Blast furnace gas (BFG) is a byproduct of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron. It has a very low heating value, about 93 BTU/cubic foot (3.5 MJ/m3), because it consists of about 60 percent nitrogen and 1820% carbon dioxide, which are not flammable.
