Coke (fuel) – Wikipedia. Kefid · In a coke oven battery, a number of ovens are built in a row with common walls between neighboring ovens. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. called gas house coke.
Blast furnace gas (BFG) is a byproduct gas released when iron is converted with coke in a blast furnace. This BFG fuel—a combination of nitrogen, carbon dioxide, carbon monoxide, and a small amount of hydrogen—has a low combustion value on its own, but it can be combined with coke oven gas or natural gas to sustain combustion.
into the modern blast furnace is one of effective measures for iron and steel industry to achieve low-carbon ironmak-ing, energy saving and emission reduction.3) The specific amount of generated coke oven gas by conventional coke-making is in the range from 410 to 560 Nm3/t of coke depending on the volatile matters in the coal charge.4) In
include Blast Furnace Gas, Coke Oven Gas, 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 application.
(COG), a by-product of coke manufacturing, as a fuel in their coke ovens, boilers, and reheat furnaces. Since the dynamic nature of the steel-making process results in widely varying needs for energy, USS had to flare some of the COG during periods of low energy demand. In an effort to save energy and reduce costs, USS developed a system at their Mon Valley Works located just outside Pittsburgh, …
Jul 19, 2014 · The injection of coke oven gas (COG) into the modern blast furnace is one of effective measures for steel industry to achieve low carbon ironmaking, energy saving and emission reduction. Coke is an essential input to the iron making process and is produced by heating coal in coke ovens.
Coke oven processing gas monitoring solution. The modern coke oven refers to a horizontal chamber coke oven with the main purpose of producing metallurgical coke and can recover coking chemical products. The coke oven furnace body consists of the furnace roof, the combustion chamber and the carbonization chamber, the ramp area, the heat storage
Blast furnace gas (BFG) is a by-product 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/m 3), because it consists of about 60 percent nitrogen and 18-20% carbon dioxide, which are not flammable.The rest is mostly carbon monoxide, which has a fairly low heating value already and some (2
Coke Oven Gas Injection in a Blast Furnace – IspatGuru
Apr 10, 2021 · There are many ways to produce gas, such as coke oven gas, producer gas, water gas, oil gas, blast furnace gas, and cracked gas. The production method of producer gas is to burn coal in the producer and limit the air at the bottom of the furnace so that the coal cannot be completely burned, thus producing a large amount of carbon monoxide

Non-recovery type Coke Oven gas based Waste Heat Recovery Boilers (WHRB) of 45 TPH each and a 32 TPH Blast Furnace Gas Fired Boiler (BFGFB). Under the project activity, SISCOL would collect and supply all the coke oven flue gases (COFG) from the Non-recovery Coke Oven plant and the excess cleaned Blast Furnace Gas
Nov 27, 2019 · In its new role, coke oven gas will partially replace both pulverized coal and metallurgical coke as reducing agents in the blast furnace process, thus contributing to reducing the carbon intensity in the blast furnace as well as the carbon footprint of the overall ironmaking operations.
Blast Furnace or Coke Oven Gas Fired Boilers. We offer single-drum and bi-drum type blast furnace gas (BFG)* boilers for the steel industry. Both packaged and site-erected options are available. The burners for these boilers are manufactured indigenously. A notable benefit of Thermax's proven design is its high reliability in spite of the peculiar characteristics of the gas such as slow-burning nature, low calorific …
Coke is an essential input to the steel-making process and is produced by heating coal in coke ovens. To make coke, coal is heated in the absence of oxygen to drive volatile matter from it. Coke oven gas, a low-BTU gas, is produced as a by-product of the process. Approximately 40% of the COG is used as a fuel in the coke oven.

Coke Oven Gas - an overview | ScienceDirect Topics
This paper documents a process for converting coke oven gas (COG) and blast furnace gas (BFG) from steel refineries into methanol. Specifically, we propose the use of blast furnace gas (BFG) as an additional carbon source. The high CO2 and CO content of BFG make it a good carbon resource. In the proposed process, CO2 is
