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.

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

However, coal gasification plants to provide liquid fuels and the chemicals are still in progress. In situ gasification still has several challenges, and no commercial in situ gasification plant seems feasible in near future. Currently, there are no new carbon capture plants for coalfired power plants on horizon. The deployment of carbon ...

Coke is made of a blend of typically three to seven coking coal grades. Coal grades have different properties: •. physical properties (density, grain size, petrography, ash, volatiles, moisture) •. chemical properties (P, S, K and Na contents, ash composition) •. coking properties (plasticity, shrinking, swelling) •.

Mining Feature: Coal Mine Explosion Prevention. There are two main types of coalmine explosions: methane and coal dust. Methane explosions occur when a buildup of methane gas contacts a heat source and there is not enough air to dilute the gas level below its explosion point. Likewise, fine particles of coal dust in the right concentration that ...

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.

The produced "syngas" consists mainly of carbon monoxide (CO), hydrogen (H 2 ), water vapor (H 2 O), and some other minor gases. These gases can then be separated through chemical processes and used as chemical feedstocks or products. Coal gasification can also be used to provide electricity in Integrated Gasification Combined Cycle (IGCC) plants.

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.
