The volatile matter of coal liberated during carbonization is collected in gas collecting mains and cooled with ammonia liquor spray. The gas cooled from 800oC to 80oC is drawn to Coal Chemical Plant by Exhauster. The residual coke is pushed out of the oven by pusher car through a guide into coke bucket.

of coal (, coke, coal tars, gasification), have advanced steadily since the late sixteenth century. Coal combustion technology has been further developed since the late nineteenth century. The coal fixedbed stoker system was invented in 1822; the firing of pulverized coal occurred in the brickkiln in 1831, and fluidizedbeds were invented in

The absence of coke ovens and sinter plants in the FINEX process allow the capital investment of the FINEX to be reduced 20% compared to a conventional BF. Without cokemaking and sintering, the FINEX is more compact and takes less space. Continued cost advantages during operation can be realized as low cost and low quality raw materials (high alumina ore, high zinc ore, noncoking coals) use ...

An electrostatic precipitator (ESP) is a piece of equipment that is used to capture dust particles that are formed or liberated by various industrial processes. The purpose of an ESP is to avoid these particulates being expelled into the atmosphere where they can cause pollution. ESPs are installed at many types of industrial plant, but they ...

In industrial chemistry, coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and ...

How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful byproducts that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.

There are two basic methods for making liquid iron: (1) a coal based process consisting of coke ovens, a blast furnace, and a basic oxygen furnace, and (2) a process in which scrap steel and/ or DRI is melted by an electric current in an electric arc furnace (EAF). A plant using the electricity based process is called a minimill.
